Vikram S. Chib, M.S., Ph.D.
Assistant Professor of Biomedical Engineering
Research Interests: Decision making; Rewards; Incentivized performance; Motivated behavior; Neuro-economics; Incentive mechanisms
Dr. Vikram S. Chib is an assistant professor of biomedical engineering at the Johns Hopkins University School of Medicine. He holds a joint appointment at the Johns Hopkins Carey Business School. A research scientist at the Johns Hopkins-affiliated Kennedy Krieger Institute, Dr. Chib works to understand how the human brain processes internal and external rewards, and how these signals motivate behavior.
Dr. Chib received his B.S. in bioengineering from University of Pittsburgh. He earned an M.S. and a Ph.D. in biomedical engineering at Northwestern University. Dr. Chib completed postdoctoral scholarship in biology and biological engineering at the California Institute of Technology as well as a Japan Society for the Promotion of Science postdoctoral fellowship at Advanced Telecommunications Research in Kyoto, Japan.

Research & Publications
Dr. Chib’s research is aimed at understanding how the human brain processes internal and external rewards, and how these signals motivate behavior. His team integrates methods from computational neuroscience, behavioral economics, functional imaging and noninvasive brain stimulation to achieve this. He hopes to translate his findings about how the brain represents motivated behavior into the design of incentive mechanisms and noninvasive brain stimulation protocols that decrease neurological and psychological impairments.
Research in the Chib Lab focuses on understanding how the brain integrates information about rewards to motivate performance. Investigators believe this knowledge will help explain how neural and behavioral processing breaks down during neurological and neuropsychiatric disorders—and help shed light on how such conditions can be treated. They hope that by understanding motivated performance, they can determine how to best incentivize individuals in real-world settings. The team utilizes engineering, cognitive neuroscience and experimental economics methods to address this issue.
