About Me

As a general gastroenterologist, I focus on improving the gastrointestinal symptoms and health of my patients as well as colorectal cancer prevention, especially in adults under 50. I’m invested in helping patients reach a better quality of life by applying evidence-based medicine and patient-centered care.

Driven by my passion to have a career at an academic institution, I joined the faculty here because of The Ohio State University Wexner Medical Center’s rich institutional environment. At the medical center, I direct the bariatric endoscopy collaborations with bariatric surgery colleagues and am also a member of the Intestinal Neoplasia group and the Fecal Microbiota Transplant Committee. In addition, I’m a designated medical leader of the Obesity Digestive Disease Area of Concentration (DDAoC) at The Ohio State University. As part of this work, I established the first GI/bariatric case conference where we discussed challenging cases in a multidisciplinary setting and updated the fecal transplant process at the Ohio State Wexner Medical Center. On a national level, I was a member of the International Relations committee at the American College of Gastroenterology between 2014 and 2020. Recently, I was also appointed as an Ohio State colon cancer prevention member for the National Cancer Institute (NCI)-sponsored ClinCaP cancer prevention consortium as well as a reviewing member of the Kidney, Nutrition, Obesity and Diabetes (KNOD) study section of the National Institutes of Health (NIH) as an expert in the field of obesity, the microbiome and colorectal health.

In 2006, I started my research career during medical school with a laboratory-based experience that enhanced my appreciation for the importance of basic research. I was fortunate to continue conducting research during my internal medicine residency and gastroenterology fellowship training at Saint Louis University. I co-established the Section of Intestinal Neoplasia and Hereditary Polyposis (INHP) when I came to the Ohio State Wexner Medical Center. My interest in the etiology and prevention of colorectal cancer has inspired me to seek additional collaborations with medical oncology and our comprehensive bariatric program at the university. As a result, I was appointed the Ohio State institutional principal investigator on a multicenter intragastric balloon (Spatz3) pivotal FDA approval study in 2016. Recently, I became a fellow of the NCI-funded Transdisciplinary Research on Energetics and Cancer (TREC) at Yale University. I also built the first international collaboration between The Ohio State University and Marmara University, one of the oldest universities in Istanbul, Turkey, for ongoing studies looking at the impact of diet and microbiome on colorectal cancer in obese/bariatric patients. In 2019, I was invited to present my work at a Grand Round at Marmara University.

Between 2016 and 2019, I participated in the Longitudinal Practice Preceptorship program where two second-year medical students were assigned to learn under me. The students were very curious and absorbed everything they learned—it was a pleasure to teach them clinical medicine. Now, I’m also constantly teaching medical students on the wards and in research methods.

I’m a member of multiple professional societies and groups, including but not limited to Center for Advanced Functional Foods Research and Entrepreneurship (CAFFRE) at Ohio State, the Association of Bariatric Endoscopy (ABE), the SWOG cancer research cooperative group, Ohio Gastrointestinal Society (OGS), American Gastroenterological Association (AGA) and American Society for Gastrointestinal Endoscopy (ASGE), and I’m a fellow of American College of Gastroenterology (FACG).

When I’m not at work, I enjoy healthy cooking, spending time with family, fitness and biking.
