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

Dr. Timchenko obtained his 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, Dr. Timchenko worked at BCM as an assistant professor, associate professor, and full professor until 2014.

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

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

PhD: Institute of Experimental Medicine, St. Petersburg, Russia.
