Y-Age Faculty

  • Waldemar Von Zedtwitz Professor of Pathology and Professor of Immunobiology; Director, Yale Center for Research on Aging (Y-Age), Pathology

    Son of teachers, Deep grew up in Hisar (Northwest India). He studied Veterinary Medicine in India, did PhD Research in University of Hannover Germany and postdoc research in Morehouse School of Medicine and NIH. He currently holds Waldemar Von Zedtwitz endowed chair and is a Professor in the Departments of Pathology, Comparative Medicine and Immunobiology and is the director of Yale Center for Research on Aging. Dixit lab studies Immunometabolism and aging. His team help establish NLRP3 inflammasome in causing ‘inflammaging’ and immunosenescence that leads to age-related chronic diseases including metabolic dysfunction. Dixit and his collaborators have identified that switch from glycolysis to ketogenesis deactivates the inflammasome and reduces immunopathology.  The ongoing work in his laboratory is aimed at understanding how adaptation to negative energy balance in a host can be harnessed to identify immunometabolic checkpoints to enhance health and lifespan.
  • Albert E. Kent Professor of Neuroscience and Professor of Psychology; Member, Kavli Institute of Neuroscience at Yale University

    Dr. Arnsten is an international expert on the molecular regulation of higher cortical circuits, and a member of the National Academy of Medicine. She received her B.A. in Neuroscience from Brown University in 1976 (where she created the Neuroscience major), and her Ph.D. in Neuroscience from UCSD in 1981. She did post-doctoral research with Dr. Susan Iversen at Cambridge University in the UK, and with Dr. Patricia Goldman-Rakic at Yale. Dr. Arnsten's research examines the neural basis of higher cognition. Her work has revealed that the newly evolved cortical circuits that underlie higher cognition are uniquely regulated at the molecular level, conferring vulnerability in mental illness and age-related cognitive disorders such as Alzheimer's Disease. Arnsten's research has led to new treatments for cognitive disorders in humans, including the successful translation of guanfacine (IntunivTM) for the treatment of ADHD and related prefrontal cortical disorders.

  • Harold Hodgkinson Professor of Biomedical Engineering; Professor, Pathology

    Dr. Rong Fan is the Harold Hodgkinson Professor of Biomedical Engineering and of Pathology. His research interest has been centered on the development and deployment of single-cell and spatial omics technologies to investigate normal development, aging, and disease. He received a B.S. in Applied Chemistry from University of Science and Technology of China, a Ph.D. in Chemistry from the University of California at Berkeley, and then completed his postdoctoral training at California Institute of Technology, prior to joining the faculty of Department of Biomedical Engineering at Yale University in 2010. He developed a microchip that allows for simultaneous measurement of 42 immune effector proteins in single cells at high throughput, which remains the highest multiplexing to date for a single-cell protein secretion assay. In collaboration with Novartis and Kite Pharma, it was applied to profiling antigen-specific activation states of chimeric antigen receptor (CAR)-engineered T cells, resulting in the discovery of novel single-cell biomarkers including polyfunctional strength index to characterize the quality of CAR-T infusion products and predict the clinical responses and immune-related adverse effects(irAEs) prior to treatment. This microchip, called IsoCode, and the automation system, called IsoLight, have been commercialized by IsoPlexis, a company co-founded by Dr. Fan. Now, this system has been used by >100 major pharmaceutical companies and cancer centers around the world for monitoring CAR-T or checkpoint inhibitor immunotherapies. Dr. Fan is also a pioneer in developing NGS-based spatial omics sequencing technologies. He conceived the concept of spatial multi-omics and developed the first spatially resolved multi-omics sequencing technology called DBiT-seq (Liu et al., Cell 183, 1665–1681, 2020) which allows for spatial co-profiling of whole transcriptome and hundreds of proteins (spatial-CITE-seq) at cellular level in complex tissues. He further developed a first-of-its-kind technology to enable spatial epigenome sequencing including spatial-ATAC-seq (Deng et al., Nature 609 (7926), 375-383, 2022) and spatial-CUT&Tag (Deng et al., Science 375 (6581), 681-686, 2022). These technologies may unlock a whole new field in spatial biology with applications in a wide range of biological and biomedical research. Dr. Fan co-founded IsoPlexis, Singleron Biotechnologies, and AtlasXomics. He is the recipient of multiple awards including the NCI Howard Temin Career Transition Award, the NSF CAREER Award, and the Packard Fellowship for Science and Engineering. He has been elected to American Institute for Medical and Biological Engineering (AIMBE), Connecticut Academy of Science and Engineering (CASE), and the National Academy of Inventors (NAI).

  • Associate Professor of Internal Medicine (Rheumatology)

    I obtained my AB from Harvard University and my MD, PhD degrees in 2011 from University of Texas Southwestern with additional training done at the University of Paris. As a part of his MD/PhD training in the laboratories of Drs. Edward Wakeland and Chandra Mohan, I identified a key role for the CXCR4/SDF-1 axis in end-organ targeting (in mouse and man), an important insight in the pathogenesis of SLE. I then did my Internal Medicine internship and residency training at Yale and joined the ABIM Short Track Pathway into the Rheumatology fellowship. I joined the laboratory of Dr. Ruslan Medzhitov in July 2014 for my postdoctoral training.  There, based on my clinical experience as a house officer, I shifted my focus to understanding how inflammation and metabolism are coordinated on an organismal level.  My work in Dr. Medzhitov's laboratory led to the discovery that different inflammatory states are coordinated with different metabolic programs, an important insight into the pathogenesis of many inflammatory diseases.  I joined the faculty as Assistant Professor in Internal Medicine (Rheumatology) in August 2017 and the Immunobiology faculty in July 2019.My lab is generally interested in trying to understand how the environment interacts with the host to affect disease trajectories. We utilize a broad range of techniques spanning disciplines spanning physiology, metabolism, inflammation, neurobiology, and immunology coupled with patient samples. On-going interests:1. Identifying and dissecting environmental determinants of inflammatory diseases. 2. Understanding inflammatory physiology3. Understanding placebo and nocebo physiology.4. Understanding the "moonlighting" functions of the immune system.5. Understanding energy allocation in host defense. (Collaboration with Dr. Rachel Perry)6. Understanding the relationship between cell death and inflammation. (Collaboration with Dr. Aaron Ring)In the clinic, I see patients with inflammatory conditions, many of the times with no clear diagnosis, as well as patients with rheumatologic diseases.

  • Assistant Professor

    My interest in microbes started in college when I did a research project on Trypanosomes, the parasite that causes African sleeping sickness. I was struck with how the membrane of the parasite changed its surface antigens to circumvent the host immune response.  My interest in the host microbe relationship continued during my MD/Ph.D., during which my thesis work focused on Varicella Zoster Virus (VZV), the cause of chicken pox and shingles.  We demonstrated that the VZV virus had co-evolved to become highly dependent on the cellular signaling proteins JNK and ERK, which was beautifully illustrated when we found that the virus had hijacked these cellular proteins and had incorporated them into the virion.  My research interests inspired my choice to pursue Infectious Diseases as a specialty.During my Infectious Disease fellowship at Yale, my clinical experiences repeatedly demonstrated that different human hosts respond very diferrently to infection.  The same microbe could produce a mild disease in one person, and an overwhelming sepsis in an another.  I especially noted that both older adults and HIV-infected individuals had particularly different responses.  With each patient I saw, the important role the host response plays in infection was underscored.   Overall, my clinical experiences have solidified the importance of the host-microbe relationship, and have pushed me to further understand the host innate immune response through my research.
