  • 00:00I'm gonna,
  • 00:01kick it off partly because,
  • 00:03I wanna sort of motivate
  • 00:04some of the themes,
  • 00:06and and directions of the
  • 00:07CSCI that Nancy briefly mentioned.
  • 00:09So, so I am a
  • 00:11a faculty in immuno biology
  • 00:13also with a secondary appointment,
  • 00:15in biomedical engineering. And, I'm
  • 00:17also an investigator of the
  • 00:19new Chan Zuckerberg Biohub New
  • 00:20York.
  • 00:22So,
  • 00:23first, I wanna talk a
  • 00:24bit about our work, and
  • 00:27then using that as a
  • 00:28as a as a basis
  • 00:29to motivate
  • 00:30the directions and themes, at
  • 00:32the CSCI.
  • 00:33So one of the things
  • 00:34we study in in in
  • 00:35my lab, it's variation,
  • 00:37in the human immune system.
  • 00:38And it it's really a
  • 00:40hallmark in the sense that
  • 00:41you see that in different
  • 00:42contexts.
  • 00:43If in in for example,
  • 00:45in terms of response to
  • 00:46immunotherapy,
  • 00:47you typically see a subset
  • 00:48of patients respond,
  • 00:50and you see that in
  • 00:51vaccination and infection responses. For
  • 00:53example, here, I'm showing,
  • 00:55the is there a point
  • 00:56zero?
  • 00:57Of
  • 01:00the mouse? Okay. Yeah. So
  • 01:02so, yeah, you see extensive
  • 01:04variation because of age, but
  • 01:06also even within young individuals,
  • 01:07you see these hundreds of
  • 01:08folds of differences in antibody
  • 01:10response
  • 01:10to vaccination.
  • 01:12And you also see,
  • 01:14in autoimmunity
  • 01:15in terms of both if
  • 01:17somebody has a higher or
  • 01:18lower risk for developing the
  • 01:19disease and also in terms
  • 01:20of having disease activities over
  • 01:22time, you see very distinct
  • 01:23patterns and trajectories within individuals.
  • 01:26And, actually, many of you
  • 01:27are wondering about questions about
  • 01:29ourselves also. Right? But, actually,
  • 01:30no general tools exist today
  • 01:32to answer questions like, did
  • 01:33I respond well to my
  • 01:35last vaccine? Am I gonna
  • 01:36develop autoimmunity in the future?
  • 01:38What about allergy?
  • 01:39And can my future health
  • 01:40trajectory be predicted based on
  • 01:41the status of of my
  • 01:42immune system? And how well
  • 01:44will I will I be
  • 01:45responding to an intervention? Right?
  • 01:47So these are questions that
  • 01:48we actually don't have generalized
  • 01:50tools right now to answer.
  • 01:52So
  • 01:53and so why do we
  • 01:54have such variable responses? And
  • 01:56and various factors, genetics and
  • 01:58environmental exposure history,
  • 02:00together shape,
  • 02:01what we call a personal
  • 02:03immune state within individuals.
  • 02:05And these kinds of states
  • 02:06can be actually quite temporally
  • 02:08stable. So we often through
  • 02:09years of looking at humans
  • 02:11and the immune system, we
  • 02:12actually often see a situation
  • 02:14like here,
  • 02:16where you see that two
  • 02:17two individuals would have distinct
  • 02:19set point states.
  • 02:21And a key question is
  • 02:22when you see something like
  • 02:23this, when you look at,
  • 02:24individuals in a population, it's
  • 02:25whether these could result,
  • 02:27right, in differences in some
  • 02:29of the outcomes I mentioned.
  • 02:30Auto d c autoimmune disease
  • 02:32risk,
  • 02:33disease activities, and how they
  • 02:34respond, and so on.
  • 02:36So, a number of years
  • 02:37ago,
  • 02:38that maybe more than a
  • 02:39decade now, my lab published
  • 02:40a study
  • 02:41showing that, independent,
  • 02:43we measure sort of the
  • 02:44immune system fairly broadly at
  • 02:46the time and show that
  • 02:47independent of factors like age,
  • 02:49sex,
  • 02:50and preexisting immunity to influenza,
  • 02:53the response to the influenza
  • 02:54vaccine
  • 02:55can be predicted based on
  • 02:56the baseline state of the
  • 02:58individual.
  • 02:59And later on, we've used
  • 03:01single cell technologies to sort
  • 03:03of unravel the sort of
  • 03:04the cellular basis of those
  • 03:05signatures
  • 03:06and also show using some
  • 03:07of the data, collected by
  • 03:09Hib c one
  • 03:10that this could actually be
  • 03:12be be generalized to other
  • 03:13other cohorts and seasons,
  • 03:15and even extended to, a
  • 03:17vaccine that's very different from
  • 03:18flu, in this case, yellow
  • 03:19fever, which is a live,
  • 03:20attenuated infection.
  • 03:22And and further on, we
  • 03:23show that this kind of,
  • 03:25baseline set points,
  • 03:26is relevant in the context
  • 03:27of autoimmunities.
  • 03:29So shown here is a
  • 03:29lupus patient
  • 03:31having varying disease activities over
  • 03:34time, a single patient. And
  • 03:35you can see that during
  • 03:36some periods, this patient has
  • 03:38high disease activity while others,
  • 03:40this patient was relatively
  • 03:42clinically quiescent.
  • 03:44So we show that by
  • 03:45looking at this specific baseline
  • 03:47immune set point during clinical
  • 03:48quiescence,
  • 03:49it actually provides predictive information
  • 03:51about the extent and the
  • 03:52intensity of the flares in
  • 03:54a subset of patients whose
  • 03:55flares resemble
  • 03:57how a healthy individual is
  • 03:58responding to a vaccine in
  • 03:59this case. So lupus is
  • 04:01very heterogeneous. For other patients,
  • 04:03we actually saw that this
  • 04:03doesn't apply. So it points
  • 04:05out to the points to
  • 04:06the very specific nature of
  • 04:08these set point variables.
  • 04:10And then we as I
  • 04:11mentioned, we use single cell
  • 04:12technology to dissect the cellular
  • 04:14basis of this and uncover
  • 04:15a circuit involving multiple cell
  • 04:17types. And I won't go
  • 04:18into the details because this
  • 04:19was published, but I wanna
  • 04:21mention one, point that's important
  • 04:23is that once we sort
  • 04:24of figure out the cellular
  • 04:25basis and what are the
  • 04:26important states of cells to
  • 04:28measure,
  • 04:29we're actually able to reduce
  • 04:30this down to ten parameters
  • 04:32that we now can measure
  • 04:33in blood. And and now
  • 04:34we can start to monitor
  • 04:36people using these ten parameters
  • 04:37that are quite easy to
  • 04:38measure and start to look
  • 04:39at them longitudinally,
  • 04:41over time and and in
  • 04:42different populations.
  • 04:44Now what about beyond classic
  • 04:45immunity of infection and and
  • 04:47and and vaccination? Right? So
  • 04:49immune cells, as many of
  • 04:50you know, they actually circulate
  • 04:52around our body, many of
  • 04:53them, and they can sense
  • 04:54sort of deviation from homeostasis.
  • 04:57And therefore, they actually are
  • 04:58collecting
  • 04:59and processing a lot of
  • 05:00information about health and disease
  • 05:02and within our bodies. And
  • 05:04so given this fact, it's
  • 05:05not surprise surprising to to
  • 05:07sort of see that the
  • 05:08immune system basically,
  • 05:10to my view, involving basically
  • 05:12all, disease and conditions. So
  • 05:14you can see that in
  • 05:15neurodegeneration,
  • 05:16in pain,
  • 05:17in in definitely in aging,
  • 05:19and metabolic health.
  • 05:21And so so the the
  • 05:22key question then boils down
  • 05:23to what exactly is immune
  • 05:25health. Can we actually measure,
  • 05:27the health of the immune
  • 05:28system and then using that
  • 05:29to link to specific outcomes
  • 05:31and understand how the immune
  • 05:32system orchestrate,
  • 05:34proper responses?
  • 05:35So to start to look
  • 05:36at that, a number of
  • 05:37years ago, we worked with
  • 05:39colleagues at the NIH,
  • 05:40who study various,
  • 05:42rare monogenic diseases. So we
  • 05:44convinced them to sort of
  • 05:45come together
  • 05:46and, look at all of
  • 05:48those patients that hit diverse
  • 05:50genetic pathways and then measure
  • 05:52them using longitudinally in some
  • 05:54of them using the same
  • 05:55systems immunology tools and also
  • 05:57matching,
  • 05:59clinically healthy individuals. So a
  • 06:01key question we ask is,
  • 06:02given this these diverse conditions,
  • 06:04can we actually detect and
  • 06:06and and and sort of
  • 06:07sense get these common deviation
  • 06:08from health by looking across
  • 06:10all these,
  • 06:11conditions?
  • 06:12So in terms of data,
  • 06:14we collected a variety of,
  • 06:16immune profiling and omics data,
  • 06:17including circulating proteins,
  • 06:19cell type specific gene expression
  • 06:21profiles, and more recently also,
  • 06:23a subset of patients, we
  • 06:24have collected single cell data.
  • 06:26And by looking at actually
  • 06:27these people, some of these
  • 06:28people over time, it was
  • 06:30again, the same picture emerges
  • 06:32despite the high penetrance and
  • 06:34the high effect size of
  • 06:35some of these DCs, how
  • 06:36they affect health. The individual,
  • 06:38it's typically the unit, actually.
  • 06:40They if you look at
  • 06:40the immune system as a
  • 06:41whole, these individuals actually don't
  • 06:43cluster necessarily into patient groups.
  • 06:45So based on that, we
  • 06:46sort of decided to sort
  • 06:48of take two machine learning
  • 06:49approaches to look at the
  • 06:50data. On the left hand
  • 06:51side, I'm showing you an
  • 06:52approach where we look,
  • 06:55look at each individual as
  • 06:56a vector of numbers, basically
  • 06:57a vector of their phenotypic
  • 06:58profiles, molecular cellular profiles, And
  • 07:01then we try to compute
  • 07:01the relationships among these individuals
  • 07:03and try to ask what
  • 07:05kind of variation exists in
  • 07:06these multimodal data. On the
  • 07:08right, we're using a more
  • 07:10supervised approach and ask, can
  • 07:11we compute a probabilistic
  • 07:13measure of whether somebody is
  • 07:15healthy or not? Right? So
  • 07:17based on so for that,
  • 07:18we know the label of
  • 07:19of everyone. So on the
  • 07:20left side, we actually don't
  • 07:21have the label of anybody.
  • 07:22We don't know what disease
  • 07:23they have and so on.
  • 07:24Right? So the surprise was
  • 07:26that when you look at
  • 07:27the emergent
  • 07:29axis of variation,
  • 07:31coming out from the left
  • 07:32approach, unsupervised
  • 07:34approach,
  • 07:35it came out with exactly
  • 07:36the, same
  • 07:37principle axis of variation
  • 07:39as this probability of being
  • 07:41healthy, basically. So in other
  • 07:42words, even if you don't
  • 07:44know who's healthy and who
  • 07:46has what disease, there's natural
  • 07:48variation in the population that
  • 07:49resembles precisely this probabilistic
  • 07:52measure of of being healthy.
  • 07:53So in other words, we're
  • 07:54learning immune health actually by
  • 07:56learning from a lot of
  • 07:56pathologies. Right? What are the
  • 07:58those are negative examples, so
  • 07:59to speak, of of what
  • 08:00it means to be having
  • 08:01a healthy immune system.
  • 08:03So and then the question
  • 08:04is, what does it mean?
  • 08:05So when you plot, these
  • 08:07individuals, so each dot is
  • 08:09a person here, and each
  • 08:11row,
  • 08:12corresponds to a monogenic
  • 08:14disease,
  • 08:15group, you can see that's
  • 08:16the clinically healthy group at
  • 08:17the top, they span a
  • 08:19huge range, and some of
  • 08:20them actually extends well into,
  • 08:22the the the sick patients.
  • 08:24Right? So as I mentioned,
  • 08:25what does it really mean,
  • 08:27when you have such a
  • 08:28wide range of of of
  • 08:29this metric, basically?
  • 08:31So then we look at
  • 08:32this in an independent set
  • 08:33of people.
  • 08:34This is the Baltimore Healthy
  • 08:35Aging cohort where they collected,
  • 08:37data
  • 08:38from, individuals across each decade
  • 08:41of life. And what you
  • 08:42can see when you compute
  • 08:43this metric on these people
  • 08:44is that there's a decline
  • 08:46in the immune health metric
  • 08:47as you go,
  • 08:48get older.
  • 08:49But, so suggesting that this
  • 08:51is actually tracking healthy aging.
  • 08:53But you can also see
  • 08:54that on the y axis,
  • 08:56there's significant remaining variation.
  • 08:59So given a a sixty
  • 09:00or seventy year old, there's
  • 09:01actually a a still a
  • 09:02y variation
  • 09:03in in according to this
  • 09:04health metric. So we look
  • 09:06into that a bit, and
  • 09:07and that actually can predict
  • 09:08vaccine responses within the especially
  • 09:10within the elderly.
  • 09:12It also, correlates with with
  • 09:14variables like BMI, for example.
  • 09:16And then it also tracks,
  • 09:18in other context, like whether
  • 09:19the heart is working well
  • 09:20and also tracking drug responses,
  • 09:22in this case, RA patients
  • 09:24responding or not to, a
  • 09:26therapy, basically.
  • 09:27So the picture I wanted
  • 09:29to paint is that, of
  • 09:30course, this is a one
  • 09:31dimensional measure that we uncover.
  • 09:33There are multiple dimension that
  • 09:34one can uncover, especially one
  • 09:36specific to disease.
  • 09:37But this one seems to
  • 09:38be emergent
  • 09:39independent of whether we look
  • 09:40at we can drop out
  • 09:41different patients. We can even
  • 09:43drop out all the healthy
  • 09:44individuals in the cohort. We
  • 09:45still get the same
  • 09:48metric
  • 09:49back, basically.
  • 09:52This is It's a public
  • 09:53service.
  • 09:56Stop. My time is up.
  • 09:57Right? Okay.
  • 10:00Okay.
  • 10:02So the
  • 10:03the the concept I'm getting
  • 10:05to is that, often when
  • 10:06we look at individuals in
  • 10:07the in the human population,
  • 10:09there are obviously some of
  • 10:10us who are maybe really
  • 10:12at this end of healthy
  • 10:13healthy,
  • 10:14and then there are ones
  • 10:15that we know with disease
  • 10:16or pathology
  • 10:17that are far off from
  • 10:18the optimal,
  • 10:19set point. But most of
  • 10:21us, I think, are still
  • 10:22healthy clinically, but inching towards
  • 10:24some sort of pathology. Right?
  • 10:26And so by by developing
  • 10:27this kind of immune health
  • 10:29metric and using the immune
  • 10:30system as a sensor, I
  • 10:31think we can start to
  • 10:32really start to quantify,
  • 10:34where someone may be at
  • 10:36and so on. So that's
  • 10:37one of the key
  • 10:38challenges that we would like
  • 10:39to tackle,
  • 10:40both in my lab and
  • 10:41also working together with other
  • 10:43others in the in the
  • 10:44CSCI.
  • 10:45So so this concludes the
  • 10:46part of the talk for
  • 10:48talking a little bit about,
  • 10:50science from my lab and
  • 10:51and and how so now
  • 10:52I'm gonna move sort of
  • 10:53onto
  • 10:54motivating
  • 10:55some of the, the key
  • 10:56themes at the CHEI. So
  • 10:58I hope I've convinced you
  • 10:59that,
  • 11:00with the immune system and
  • 11:02what it's sensing,
  • 11:03we can really move beyond
  • 11:05the genome, which in a
  • 11:06way, it's a static information
  • 11:08store of of what may
  • 11:09be possible.
  • 11:10But but the immune system
  • 11:12is really sensing, detecting what's
  • 11:14going on right now and
  • 11:15and in the past as
  • 11:16well and integrating that information.
  • 11:18And it's it's it's I
  • 11:19I would argue that that's
  • 11:20why it's actually gonna tell
  • 11:21us a lot more about
  • 11:23both the status of the
  • 11:24of the body right now,
  • 11:25but also what's gonna happen
  • 11:27in the future. Right? So,
  • 11:28therefore, the the grand challenge
  • 11:29is can we uncover the
  • 11:30connection between the immune system
  • 11:32and physiology
  • 11:33and thereby predict and modulate
  • 11:35personal immunity and health.
  • 11:37So at the c h
  • 11:38CSCI,
  • 11:39we
  • 11:40help to develop and bring
  • 11:41together both people and interdisciplinary
  • 11:45approaches to monitor, predict, understand,
  • 11:48and modulate personal immunity and
  • 11:50health for the benefit of
  • 11:51all.
  • 11:53So to achieve this mission,
  • 11:54we have some philosophies and
  • 11:55and and and and and
  • 11:57and pillars.
  • 11:58So one is that,
  • 12:00many of you heard of
  • 12:01systems immunology,
  • 12:03and some of you may
  • 12:04think of it as immunology
  • 12:06with lots of omics data.
  • 12:07But I wanna argue that
  • 12:08it it's more than that,
  • 12:10actually.
  • 12:10It it I think thinking
  • 12:12the cyst immune system is
  • 12:13a system,
  • 12:14and then and then designing
  • 12:16unique studies and and and
  • 12:17and and questions to address.
  • 12:19For example, how
  • 12:21do immune cells and also
  • 12:23going up the hierarchy, multiple,
  • 12:25populations of cells integrate information?
  • 12:28And can we understand how
  • 12:29the interactions among these components
  • 12:31actually give rise to outcomes?
  • 12:32Right? So that's a grand
  • 12:33challenge in understanding something as
  • 12:35complex as an immune system.
  • 12:36And to address that, I
  • 12:37think we need to think
  • 12:39of unique approaches and and
  • 12:40and and and study designs.
  • 12:42And then the second aspect
  • 12:43is people.
  • 12:45We we want to enable
  • 12:46and cultivate.
  • 12:47So we wanna collaborate with
  • 12:49at Yale, there's a lot
  • 12:50of exciting,
  • 12:52groups and also, programs such
  • 12:54as HTI, YCIO, and the
  • 12:56engineering school. We wanna bring
  • 12:57together across Yale and the
  • 12:59and also the world to
  • 13:00push the frontiers of this
  • 13:02field,
  • 13:03and and and and and
  • 13:04really,
  • 13:05drive forward also this predictive
  • 13:07immune cell engineering,
  • 13:09theme that I'm gonna highlight
  • 13:10and again for the benefit
  • 13:11of all. And in terms
  • 13:13of people, also education and
  • 13:14training is another mission. We
  • 13:16wanna develop a new generation
  • 13:17of computational and systems immunologists,
  • 13:19immune cell engineers,
  • 13:21and technicians and engage citizens
  • 13:23in research.
  • 13:24And then on the science
  • 13:26side, I'm listing sort of
  • 13:27four pillars.
  • 13:29Pillar one, I think I
  • 13:30mentioned that already. It's it's
  • 13:31don't forget physiology. Sometimes we
  • 13:33get too hung up with
  • 13:34measuring just the immune system,
  • 13:36obviously, but I think we
  • 13:37have to measure physiology at
  • 13:38the same time. And second
  • 13:40is utilize human immune variation.
  • 13:42So human immune variation is
  • 13:43often sometimes thought of as
  • 13:45a as a as a
  • 13:46as a as a as
  • 13:46a roadblock.
  • 13:47But in a way, it's
  • 13:48the it's the only way
  • 13:49to actually utilize natural variations,
  • 13:52and it's a human it's
  • 13:53an experiment, natural experiment that
  • 13:54we can utilize and learn
  • 13:56a lot using these new
  • 13:57technologies.
  • 13:58The pillar two is measure.
  • 14:00Right? We knew new technologies,
  • 14:03and and and so, therefore,
  • 14:04the application and fine tuning
  • 14:06and development of cutting edge
  • 14:07immune monitoring and molecular profiling
  • 14:09approaches
  • 14:10are are central.
  • 14:11And then the other pillar,
  • 14:13it sells as as as
  • 14:14tools.
  • 14:15So I I mentioned briefly
  • 14:16on how immune cells, some
  • 14:17of them can traffic and
  • 14:19can sense information. So how
  • 14:20can we harness them as
  • 14:21both natural sensors? Because some
  • 14:23of them already are sensing
  • 14:25things, but we don't have
  • 14:26the full book to decode
  • 14:27what it means. For example,
  • 14:29I can see a certain
  • 14:30T cell in the blood
  • 14:31and and may may have
  • 14:32information about the liver, about
  • 14:34the kidney that we haven't
  • 14:35been able to decode those
  • 14:36yet. So that's what I
  • 14:37call natural sensing. The other
  • 14:39one, it's it's more ambitious,
  • 14:40but at the same time,
  • 14:40much more controllable. Right? Can
  • 14:42we engineer these cells
  • 14:44so that they go to
  • 14:44specific locations, actually collect data
  • 14:46for us? That's one. And
  • 14:48second is one is once
  • 14:49those data are collected, can
  • 14:50we act? And third, it's
  • 14:52eventually, can you actually make
  • 14:53the cells,
  • 14:55act by themselves? So I
  • 14:56hope Wendell is gonna highlight
  • 14:57some of the pioneering approaches
  • 14:58that he has,
  • 15:00done in his lab on
  • 15:01that on that front. And
  • 15:02the last pillar, it's compress
  • 15:04and predict. Right? Because we
  • 15:05generate lots of data,
  • 15:07but data is just data.
  • 15:09And and if without compressing
  • 15:11and and transforming them into
  • 15:12causal predictive models,
  • 15:15we we we cannot really
  • 15:17act on it, and also
  • 15:18we cannot understand. So I
  • 15:19hope it's we can develop
  • 15:20models that can allow us
  • 15:21to compress the data, transform
  • 15:23them into tools, but also
  • 15:25understanding.
  • 15:27So with that, I wanna
  • 15:28highlight just a few things
  • 15:29in the last,
  • 15:30five minutes
  • 15:31that sort of highlights some
  • 15:33of the efforts, we have
  • 15:34started to push in these
  • 15:35these directions.
  • 15:37So on the on the
  • 15:37AI front, if you think
  • 15:39look look at the the
  • 15:40immune system as a sort
  • 15:41of a multiscale machine. Right?
  • 15:42So going from molecules
  • 15:44within cells like DNA, proteins,
  • 15:46and RNA,
  • 15:47Together, they they orchestrate
  • 15:49the behavior of cells, and
  • 15:51cells, of course, exist in
  • 15:52different types states, and they
  • 15:53they have different compositions and
  • 15:55different tissues, and then so
  • 15:56on. You can move up
  • 15:57the the sort of chain
  • 15:58all the way to the
  • 15:59individual and then human population
  • 16:01level. And when you think
  • 16:02about machine learning and and
  • 16:04AI,
  • 16:05it machine learning and AI
  • 16:06is actually a mapping problem.
  • 16:07Right? So machine learning, you
  • 16:08try to develop a mathematical
  • 16:10model that can map certain
  • 16:12types of input to an
  • 16:13output. Right? So you've seen
  • 16:15the phenomenal alpha four, for
  • 16:17example, which maps sequences, protein
  • 16:20sequences
  • 16:20into structure, right, and map
  • 16:22sequences into function. So if
  • 16:24you have a mutation in
  • 16:25the protein coding gene, we
  • 16:26wanna predict, is it gonna
  • 16:28be bad, for example. So
  • 16:29you're quite familiar with these
  • 16:30kinds of mapping functions. So
  • 16:32the challenge in the in
  • 16:33the immune system, it's it's
  • 16:34it's the mapping problem across
  • 16:36these scales, so to speak.
  • 16:37Right? So in each one
  • 16:38of these scales, you can
  • 16:39sort of measure different features.
  • 16:41So we often now see
  • 16:42gene expression data. We often
  • 16:44see cell composition and cell,
  • 16:47phenotype data. But can we
  • 16:48map those,
  • 16:50features onto
  • 16:52type ontogeny,
  • 16:54onto dynamics and trajectory,
  • 16:56and onto functions, right, and
  • 16:57all the way to, the
  • 16:58individual organismal level that, I
  • 17:01I mentioned earlier today, basically.
  • 17:03Right? And the challenge is
  • 17:04data, actually.
  • 17:06We talk about big data
  • 17:07a lot these days, but,
  • 17:08actually, we have relatively limited
  • 17:09data, partly because they're expensive
  • 17:11and and so on.
  • 17:13So that's where, one of
  • 17:14the efforts, we're teaming up,
  • 17:15we're we're we're driving towards
  • 17:17is this project called the
  • 17:17human immunome project
  • 17:19that sort of,
  • 17:22sort of checks off this
  • 17:22both these pillars in terms
  • 17:24of leveraging the human,
  • 17:26population in in in across
  • 17:27the world in this case
  • 17:28and connection to physiology,
  • 17:30but also the measurement aspects
  • 17:32that I mentioned. So we
  • 17:33think that the time is
  • 17:34ripe to do this given
  • 17:36the public. It's it's becoming,
  • 17:37really, in a in a
  • 17:39way understand better about the
  • 17:40the the the the importance
  • 17:41of the immune system, and
  • 17:42technology is at a point
  • 17:43where we we can really
  • 17:44start to measure quite a
  • 17:45lot. And and then, you
  • 17:47know, the AI revolution that's
  • 17:48going on. And so this
  • 17:49is a project,
  • 17:50that, I've been working together
  • 17:52on, on the science side
  • 17:53together with Shai,
  • 17:55Shenor of Technion, for the
  • 17:56past couple of years with
  • 17:57contributions from a number of
  • 17:58people.
  • 17:59So the goal is really
  • 18:01to map, this kind of
  • 18:02personal immune states along major
  • 18:04axis of variation
  • 18:05across the world. And we
  • 18:07wanna create an open,
  • 18:08data resource, to empower both
  • 18:10research and train the kind
  • 18:11of AI model I mentioned.
  • 18:13So we wanna sort of
  • 18:14cut across
  • 18:15populations
  • 18:16in in terms of environment,
  • 18:18across the whole lifespan,
  • 18:19the gender and and geography,
  • 18:21of of course. Initially, we're
  • 18:22gonna focus on predisease.
  • 18:25And I I think that's
  • 18:25actually a huge area to
  • 18:26fill because we we're gonna
  • 18:28monitor these people longitudinally,
  • 18:30as well.
  • 18:31And so this actually needs
  • 18:32to be a a truly
  • 18:33global effort for both scientific,
  • 18:35so leveraging the variation across
  • 18:37the globe, and also for
  • 18:39equity reasons. So so far,
  • 18:40a lot of the kind
  • 18:41of data I mentioned that
  • 18:41we're collecting in academia and
  • 18:43some companies, they tend to
  • 18:44be mostly in the US
  • 18:46and in EU. We have
  • 18:47actually very little data, dense
  • 18:49datasets,
  • 18:50in other from other parts
  • 18:51of the world.
  • 18:52So just briefly, the way
  • 18:54we're gonna do this will
  • 18:54be we're gonna start with
  • 18:56the phase one sort of
  • 18:57ten sites or so across
  • 18:58the world. We're gonna deploy
  • 19:00the state of the art
  • 19:00technology to enroll about ten
  • 19:02thousand to fifteen thousand people
  • 19:04and follow them over time
  • 19:05and also give them a
  • 19:06vaccine to probe them. And
  • 19:07then with that data, we
  • 19:08hope to be able to
  • 19:09learn
  • 19:10sort of a compression scheme,
  • 19:11so to speak. Right? How
  • 19:12how can we measure all
  • 19:13of these ten to the
  • 19:14seventh or so parameters, but
  • 19:16with maybe a few thousand
  • 19:17measurements
  • 19:17that can still capture most
  • 19:19of the variation
  • 19:20in the population.
  • 19:21And then we're gonna create
  • 19:22this new monitoring kit that
  • 19:24will be cheaper and and
  • 19:25and simpler to deploy
  • 19:27across the whole,
  • 19:28many more sites to to
  • 19:29scale up the number of
  • 19:30people we can look at.
  • 19:32So the goal right now,
  • 19:33it it's it's it's really
  • 19:34the the scaling
  • 19:36down. It's really important because,
  • 19:37otherwise, this is still a
  • 19:38very, very expensive project. So
  • 19:40based on the data we
  • 19:41have so far,
  • 19:42based on our and other
  • 19:43studies,
  • 19:44we think this kind of
  • 19:45compression is possible.
  • 19:47So this is just showing
  • 19:48you that some of the
  • 19:49sites, that that's under discussion,
  • 19:52and and we hope to
  • 19:53launch one, here at Yale,
  • 19:55to to coordinate and to
  • 19:56build this kind of site
  • 19:57model that can be replicable
  • 19:58across the world.
  • 20:00The other pillar I wanna
  • 20:01quickly highlight is cells as
  • 20:02tools and which it's the
  • 20:04Chan Zuckerberg Biohub's goal. It's
  • 20:05the harness immune cells as
  • 20:06natural and engineer sensors and
  • 20:08modulators.
  • 20:10We wanna
  • 20:11take these cells eventually for
  • 20:12early disease detection and prevention,
  • 20:15sort of motivated by the
  • 20:17immune health metric sensing I
  • 20:19mentioned earlier. Right? So you
  • 20:20can see that clinically healthy
  • 20:21people, they have underlying
  • 20:23potential pathologies that we can
  • 20:24we can we can detect.
  • 20:26So one of the ways
  • 20:27it's it's you can actually
  • 20:29engineer cells. You can sort
  • 20:30of, like, guide them into
  • 20:31specific locations
  • 20:32and express certain sensors, and
  • 20:34they can they can sort
  • 20:35of collect data on tissues.
  • 20:37And that would be a
  • 20:37dream in in also from
  • 20:39the basic science standpoint. Imagine
  • 20:40you actually got tools now
  • 20:42that you can go into
  • 20:43the tissues without invasiveness
  • 20:45and be able to collect
  • 20:45data, basically.
  • 20:47So,
  • 20:48yeah. So this was also
  • 20:50reminds me of the magic
  • 20:51school bus in in case
  • 20:52some of you have seen
  • 20:52that episode. I remember that,
  • 20:54when I when I watched
  • 20:55it with my son many
  • 20:56years ago.
  • 20:57So
  • 20:58the Biohub, it's it's a
  • 21:00sort of a two pronged
  • 21:01structure. One is a physical
  • 21:03hub. So the main hub
  • 21:04is in New York. There
  • 21:05will be a component in
  • 21:06New Haven. There's also the
  • 21:07investigator program that will be
  • 21:09spread out through the three
  • 21:10universities. So the partners at
  • 21:11Yale, Rockefeller, and Columbia.
  • 21:13So an investigator,
  • 21:15RFA just went out. So,
  • 21:17I encourage, you to apply
  • 21:19and also go to the
  • 21:20webinar. If you have scientific
  • 21:22questions, after the webinar, please
  • 21:23feel free to contact,
  • 21:25Alisa and also myself.
  • 21:27So and finally, please become
  • 21:30look look at our website
  • 21:31and consider becoming a member
  • 21:32and join our contact list.
  • 21:34And you can also,
  • 21:36check check us out on
  • 21:37social media. And, also, you
  • 21:39can check out the members
  • 21:40and various other, information on
  • 21:41the website. And And we
  • 21:43have a seminar and Chalk
  • 21:44Talk series. And for the
  • 21:45past year and a half,
  • 21:46we have both outside and
  • 21:48internal speakers.
  • 21:49It's been quite well attended
  • 21:51and a lot of, interesting
  • 21:52discussions, especially during the Chalk
  • 21:53Talks because we encourage folks
  • 21:54to come and interrupt and
  • 21:56ask lots of questions, and
  • 21:58that can lead to both
  • 21:58new collaborations and also new
  • 22:00understanding.
  • 22:01So with that,
  • 22:03yeah, send us any ideas
  • 22:05and suggestions.
  • 22:06I wanted to sort of
  • 22:07end by saying that,
  • 22:09CSCI, of course, cannot do
  • 22:11what I
  • 22:12propose alone.
  • 22:13So we are, already actively
  • 22:15engaged as you saw with
  • 22:17both Yale colleagues and also
  • 22:18partners around the world. So
  • 22:20today, we're gonna highlight, each
  • 22:21one of these pillars with
  • 22:23the speak with the invited
  • 22:24speakers. So first on pillar
  • 22:26one would be, Ling
  • 22:27and Steve. They will talk
  • 22:29about,
  • 22:29human,
  • 22:30immunology and variation in response
  • 22:32to COVID nineteen,
  • 22:34and also vaccine and infection
  • 22:35response signatures. In terms of
  • 22:37measurement and monitoring,
  • 22:38Wei Ka, who's a pioneer,
  • 22:40in in in random laser
  • 22:41technologies, she's gonna touch on
  • 22:43deep tissue imaging.
  • 22:45In terms of engineering cells,
  • 22:47Wendell Lim is one of
  • 22:49the pioneers, in this field,
  • 22:50so he's gonna tell us
  • 22:51about their efforts.
  • 22:53And finally, in in AI
  • 22:55and also AI models,
  • 22:57we're lucky to have, Deep
  • 22:58Jaitley,
  • 22:59who's one of the early,
  • 23:02pioneers in deep learning on
  • 23:03generative models as well as
  • 23:05Maria who just, joined us
  • 23:06at Yale. She's gonna talk
  • 23:07about TCR specificity prediction.
  • 23:10With that, thank you for
  • 23:11your attention.
  • 23:20Any questions?
  • 23:23And visit us. And this
  • 23:25is also where the CSCI
  • 23:26seminar
  • 23:27is being held.
