Biography

Dr. Sayan Nandi received his Ph.D. degree from Albert Einstein College of Medicine, NY, where he studied the roles of hematopoietic cytokines in bone and brain development. He subsequently completed postdoctoral studies in Columbia University, NY, focusing on the roles of small noncoding RNAs in brain function, and in Einstein, where he studied fibroblast growth factor signaling in telencephalon development and in hippocampal neurogenesis and synaptogenesis. As a junior faculty in the research-track at Einstein, Dr. Nandi investigated the roles of microglia in synaptic remodeling and behavior and he further received two co-PI NIH pilot awards. This work also formally established the roles for Iba1, a protein that has long been known as a microglial marker, in normal brain function. As an Assistant Professor in the tenure-track at Howard University College of Medicine, Dr. Nandi focuses on the discovery of neural mechanisms as well as those related to neuroimmune interactions underlying neurodevelopmental and neuropsychiatric disorders, as well as neural injury.
