Vivek Rudrapatna, MD, PhD

Assistant Professor In Res

Vivek Rudrapatna is a physician-scientist and Inflammatory Bowel Disease specialist in the Division of Gastroenterology. His research group develops methods for analyzing healthcare data with the goal of improving clinical decision making. Towards these goals, his team draws inspiration from a variety of disciplines within the data sciences, including biostatistics, natural language processing, machine learning, and artificial intelligence.

Current areas of focus include:
-Information extraction from clinical notes using Large Language Models
-Retrospective emulation of clinical trials using EHR data
-Reducing diagnostic delays using machine learning
-Personalizing treatment selection using EHR and RCT data
-Reinforcement learning for optimal clinical decision making
