Jeffrey Tasker, Ph.D.

Catherine and Hunter Pierson Chair in Neuroscience
Professor of Cell and Molecular Biology

Website: The Tasker Lab

Dr. Tasker teaches NSCI 3310/6310 (Cellular Neuroscience) and NSCI 7110 (Graduate Neuroscience).

Research Interests

The Tasker lab uses brain-slice patch-clamp, genetic, immunochemical, and molecular biology approaches to study the neural circuit organization and electrical and molecular signaling of hypothalamic neuroendocrine cells and amygdalar neurons involved in the brain regulation of physiological homeostasis, stress, depression, obesity, and stress disorders such as posttraumatic stress and anxiety.
