Dr. Kumar received his Bachelor's degree from the University of Chicago in Biology. As an undergraduate he worked with Dr. Robert Haselkorn on the genetics of the photosynthetic bacterium Rhodobacter capsulatus. He obtained his PhD from the University of California, San Diego working under the mentorship of Dr. Michael G. Rosenfeld.  Dr. Kumar biochemically and structurally characterized the NAD+ binding transcriptional corepressor C-terminal binding protein (CtBP). He joined the laboratory of Dr. Joseph Takahashi at Northwestern University as a postdoctoral researcher.  He subsequently moved with Dr. Takahashi to UTSW and is currenty an Instructor of Neuroscience.   

Dr. Kumar works on motivational reward pathways whose misregulation lead to diseases such as addiction, attention deficit and hyperactivity disorder, and depression.  He uses high throughput behavioral screens in mice to identify mutants in cocaine response and open field behavior.  This classic forward genetic approach is powerful but difficult to execute for behavioral assays in mice.  Dr. Kumar has developed several novel approaches to overcome these limitations in screening.
