AZA Allsop is an artist, neuroscientist, and psychiatrist who conducts research at the intersection of social cognition, music mindfulness, and psychedelics. His research and clinical work is guided by the belief that decoding these tools will provide a better understanding of how social groups function and offer insights into treating mental suffering and enhancing the evolution of society at large. AZA studied Biology, Philosophy, and Jazz Studies at North Carolina Central University, received his MD from Harvard Medical School, PhD in Neuroscience from MIT and was an Emerson Scholar at Berklee College of Music. He completed his residency in the Department of Psychiatry at Yale University where he served as co-chief resident of the Clinical Neuroscience Research Unit and is currently an Assistant Professor in Yale’s Department of Psychiatry and Director of the Center for Collective Healing at Howard University. He teaches meditation, yoga, and music and co-founded Renaissance Entertainment and Mefreely, companies that combine music, science, and community building to drive social change.

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.

Jonathan Demb is a Professor in the Department of Ophthalmology & Visual Science with secondary appointments in the Department of Cellular & Molecular Physiology and the Department of Neuroscience. Dr. Demb obtained his doctoral degree from Stanford University and did postdoctoral training at the University of Pennsylvania. Demb was a faculty member at the University of Michigan before moving to Yale in 2011. The Demb lab investigates the cellular and synaptic mechanisms that enable visual processing by the mammalian retina. Major accomplishments include identifying fundamental nonlinearities at retinal synapses that mediate specialized spatial processing by retinal ganglion cells; elucidating the role of disinhibition in visual contrast processing; characterizing asymmetries between the retina's ON and OFF pathways; determining roles of NMDA-type glutamate receptors in ganglion cell receptive fields; identifying characteristic properties of cone-mediated vision in the mouse retina; developing the use of a glutamate sensor (iGluSnFR) for study of retinal circuitry; identifying novel amacrine cell circuits using optogenetic technology; and testing experimental therapies in mouse models of retinal disease. Demb is a Reviewing Editor at the Journal of Neuroscience and is on the Editorial Board of PLoS Biology. He was awarded the Cogan Award in 2013 from the Associate for Research in Vision and Ophthalmology (ARVO) to recognize his contributions to the field of retinal neuroscience.

Dr. George Dragoi is an Associate Professor of Psychiatry and of Neuroscience in the Department of Psychiatry and a member of the Wu-Tsai Institute at Yale University School of Medicine in New Haven. He received his M.D. degree from the Grigore Popa University of Medicine and Pharmacy of Iasi, Romania and his Ph.D. degree in Behavioral and Neural Science from Rutgers University. He completed his postdoctoral studies and was a Research Scientist at the Picower Institute for Learning and Memory at the Massachusetts Institute of Technology (MIT), where he revealed the existence of preconfigured cellular assemblies that pre-play in time the spatial sequences occurring during a future novel spatial experience in naive animals. Dr. Dragoi studies the dynamic interplay between externally-driven and preconfigured internally-generated representations of the external world to understand memory formation and spatial navigation. He aims to map the neural circuits and decipher the neuronal codes underlying the formation of these representations across brain development and in adulthood using large-scale high-density electrophysiology and computational methods for data analysis. Recently, he conceptualized the existence of a generative grammar in the brain that could support the brain’s ability to express internally generated representations about the world. Dr. Dragoi’ current research focuses on the role of neuronal activity and prior experience in cellular assembly organization and animal learning with implications for our better understanding of neuro-psychiatric diseases.
