Dr. Kohli received his medical degree from the Armed Forces Medical College, India in 1999 and his MS in clinical investigation from Northwestern University in 2006. While at Northwestern he first spent three years as a pediatric gastroenterology and hepatology fellow and then subsequently as a transplant hepatology trainee before relocating to the University of Cincinnati in 2007.
His research work has focused on the pathogenesis of obesity related fatty liver disease (NAFLD). In particular, he has focused upon the role of bile acid signaling as a mechanism for NAFLD resolution after weight loss surgery. His work has also shed light on reactive oxygen stress in the generation and regulation of the extreme stage of this disease; nonalcoholic steatohepatitis (NASH). He has published many peer-reviewed articles including articles in Nature, Nature Reviews, The Journal of Biological Chemistry, Hepatology, Journal of Pediatrics, and The American Journal of Physiology. He is the author of many book chapters and review articles. He also is the recipient of the 2007 George Ferry Young Investigator Award from the Children's Digestive Health and Nutrition Foundation, a Fellowship award from the American Association for the Study of Liver Diseases, Takeda Research Innovation Award from the North American Society for Pediatric Gastroenterology, Hepatology and Nutrition Foundation.

Dr. Kohli and his team of scientists have focused their work on obesity-related fatty liver disease (NASH). One key advance was when back in 2010, when Dr. Kohli’s laboratory highlighted the role of fructose, such as that present in food containing high fructose corn syrup (HFCS), in triggering injury and scarring within the liver.
Dr. Kohli’s team has developed a surgical model in mice that is now used by researchers around the world to better understand how weight loss surgeries improve obesity and its associated morbidities, such as NASH. The understanding as to how weight loss surgery such as the vertical sleeve gastrectomy (VSG) works was previously thought to be based on the dogmas of restriction and malabsorption. We have shown that bile acid signaling is critical to the success of these surgical procedures. Now we use the VSG surgical technique on diet-induced obese mice, and try to further understand the role of bile acids and bile acid signaling targets such as the farnesoid X receptor (FXR) pathway to better understand the specific mechanism behind the success of these surgical procedures.
