Assistant Professor
Biomedical Sciences

Education
BS, Life Science, Pohang University of Science and Technology
PhD, Rockefeller University

Past Experience
Since obtaining her PhD, Dr. Jang has completed two postdoctoral fellowships focused on circuit function. At Rockefeller University she developed novel molecular tools to study communication between neuros. At a second postdoctoral fellowship, Dr. Jang trained at the Buck Institute for Research on Aging at the University of California, San Francisco, where she expanded into aging biology and mouse models to study how thirst and water-balance circuits change with age.

Research Areas
As a neuroscientist, Dr. Jang researches how aging alters neural circuits that regulate essential physiological processes. She focuses on brain circuits that control thirst and fluid balance, which become increasingly vulnerable with age with the hope the understanding how these systems fail may help explain dehydration and declining health in older adults.

Teaching Areas
Dr. Jang will be teaching BMS 7334 (Biomedical Sciences II) and BMS 5380 (Principles of Physiology).

Dr. Yang says…
“I am driven by a long-standing fascination with how the brain controls behavior through neural networks. Aging affects how we eat, drink and maintain internal balance, yet we know little about how normal brain aging drives these changes. By combining molecular genetics, functional neural recording, behavioral analysis, and physiology, I am to uncover how aging reshapes the brain circuitry and homeostatic regulation.”
