Nonalcoholic fatty liver disease (NAFLD) is a condition in which liver cells have a built-up of extra lipids or fats. It’s the most common liver disease in children, and more research into NAFLD is essential.

My research and patient care specializations are in fatty liver disease, pediatric gastroenterology and pediatric obesity. In my research, my colleagues and I attempt to solve the problems associated with childhood obesity and fatty liver disease. Specifically, we are looking to uncover better prevention and treatment strategies for pediatric obesity and fatty liver disease, the leading cause of chronic liver disease across the globe.

As a gastroenterologist, I am most interested in pursuing research related to pediatric obesity and clinical trials for fatty liver disease and obesity — especially advanced prevention and treatment approaches. In clinical studies on fatty liver disease, my colleagues and I also aim to identify genetic and environmental factors that can influence outcomes. We are also testing and validating noninvasive biomarkers to improve diagnosis and treatment approaches.

I recognize the enormous negative impact of the obesity epidemic on children's health throughout the United States and the world. There is a critical need to identify better prevention and treatment strategies. I enjoy working with children and their families and helping children lead longer, healthier lives. My parents were exceptional and dedicated doctors (a pediatrician and a general surgeon). Their example inspired and encouraged me to become a physician.

At the Cincinnati Children’s Hospital Medical Center, we have a large multidisciplinary program for children and youths with nonalcoholic fatty liver disease. Through this program, my colleagues and I have successfully participated in several clinical trials. We continue to offer children with NAFLD the opportunity to join research studies and clinical trials.

Our Steatohepatitis Center Team received the 2015 Faculty award for superior clinical and research accomplishments. I was nominated by my peers as a "Top Doctor" in Cincinnati Magazine and Cincy magazine from 2015-2019. In addition, I have given numerous presentations across the country on childhood obesity and NAFLD.
