Deepta Bhattacharya received his PhD from the University of California, Berkeley, studying the role of the NF-kB transcription factor in survival and B cell class switching. For his postdoctoral fellowship, he trained at Stanford University, studying the cell biology of hematopoietic stem cells and their differentiated progeny. In 2008, he began his own lab at Washington University in St. Louis, first as an Assistant Professor and then as a tenured Associate Professor.  Dr. Bhattacharya returned in 2017 to his birthplace of Tucson to join the Department of Immunobiology, where his lab continues to study both stem cells and antibody responses to infections and vaccines.
