Dr. Vikram Chib is an assistant professor in the Department of Biomedical Engineering at the Johns Hopkins School of Medicine and a research scientist at Kennedy Krieger Institute.


Dr. Chib obtained his bachelor's degree in bioengineering at the University of Pittsburgh, and earned a master of science degree and Ph.D. in biomedical engineering from Northwestern University. Following his Ph.D., Dr. Chib was a Japan Society for the Promotion of Science (JSPS) Postdoctoral Fellow at Advanced Telecommunications Research (ATR) in Kyoto, Japan. Before coming to Johns Hopkins, he was a postdoctoral scholar in the Division of Biology and Biological Engineering at the California Institute of Technology and a member of the Computation & Neural Systems and Behavioral & Social Neuroscience programs.


The goal of Dr. Chib’s research is to understand how the human brain processes internal and external rewards, and how these signals motivate behavior. To this end, his group uses methods from computational neuroscience, behavioral economics, functional imaging, and noninvasive brain stimulation. Dr. Chib aims to translate his basic findings of the how the brain represents motivated behavior to the design of incentive mechanisms and noninvasive brain stimulation protocols that reduce neurological and psychological impairments.
