Abha K Rajbhandari, PhD
- ASSISTANT PROFESSOR | Psychiatry
- ASSISTANT PROFESSOR | Neuroscience
Dr. Rajbhandari is an Assistant Professor in the departments of Psychiatry and Neuroscience at the Icahn School of Medicine at Mount Sinai. Dr. Rajbhandari obtained her Ph.D. in Neuroscience from the University of Wisconsin-Madison, where she studied the role of the amygdala sub-regions in regulation of stress and sensorimotor gating via norepinephrine and the neuropeptide- corticotropin releasing factor. Prior to joining Mount Sinai, Dr. Rajbhandari was a postdoctoral fellow at the University of California-Los Angeles, where her research was focused on understanding the role of the neuropeptide, pituitary adenylate cyclase activating peptide in regulation of fear and stress behaviors via amygdala sub-regions. She also developed a mouse model of stress-enhanced fear learning during her work.
Dr. Rajbhandari is a recipient of the Akira Arimura Award for Young Investigators for Excellence in VIP/PACAP Research, two times recipient of the Brain and Behavior foundations’ prestigious NARSAD award for young investigators, WhiteHall foundation grant and the Friedman Brain Institute Pilot Grant award.
At the Icahn School of Medicine. Dr. Rajbhandari’s team focuses on the brain, vagus nerve and body mechanisms of fear, stress and anxiety via neuromodulatory actions of norepinephrine and neuropeptides.
