Biography
Dr. Sayan Nandi received his bachelor's degree in Physiology with first class (and Physics and Chemistry as electives) from Presidency College, Kolkata, India and his master's degree (in first division) in Biotechnology from GCGEB at University of Calcutta, India. He then completed another master's degree in Developmental and Molecular Biology with Neuroscience focus (with Distinction) and his Ph.D. degree from Albert Einstein College of Medicine (AECOM), NY, where he studied the roles of colony-stimulating factor-1 receptor (CSF-1R), the principal macrophage and microglial growth factor receptor, in bone and brain development.
Dr. Nandi subsequently completed two postdoctoral fellowships in Neuroscience from Columbia University, NY, and AECOM, before joining as a Junior Faculty (research track) at AECOM. There he focused on the roles of microglia in synaptic remodeling and brain injury and further received two co-PI R21 awards (from NIMH and NINDS). This work also formally established the roles for Ionized calcium binding adapter protein 1 (Iba1 a.k.a. AIF1), a protein that has long been known as a "microglial marker", in normal brain function.
As an Assistant Professor (tenure-track) at Howard University College of Medicine (HUCM) since July 2022, Dr. Nandi focuses on the discovery of neuroinflammatory and neurophysiological mechanisms relating to immune cell (such as microglia)-neuron interactions underlying neurodevelopmental and neuropsychiatric disorders (such as autism and schizophrenia) and neural injury (such as stroke). He has further received NARSAD young investigator award from Brain and Behavior Research Foundation (BBRF). Dr. Nandi is also the co-Director of the medical/graduate course at HUCM, Structure and Function 2, which focuses on the development, organization and function of the nervous system.
