About

Biography

I came to Cincinnati Children’s Hospital Medical Center in June of 2014 from Baylor College of Medicine (BCM), where I was a professor of pathology and working in the Huffington Center on aging.

I obtained my PhD in the Institute of Experimental Medicine in St. Petersburg, Russia in the field of liver biology and molecular genetics. After moving to the US, I worked at BCM as an assistant professor, associate professor, and full professor until 2014.

I am currently a professor in the Division of General and Thoracic Surgery at Cincinnati Children's within the UC Department of Surgery. I am also the director of the Liver Tumor Program. I investigate mechanisms of liver cancer in children and adults, mechanisms of NAFLD, and mechanisms of age-associated diseases.

I am a member of the Digestive Health Center (Cincinnati Children's) and a professor in the Department of Surgery at the University of Cincinnati.
