I work on LLM agents for clinical genomics: how to build them, how to evaluate them, and when a person should stay in the loop. I am a Research Fellow at Boston Children’s Hospital and Harvard Medical School. I go by Ravi.

I received my PhD in Computer Engineering from the University of Central Florida, where I worked on explainable AI for detecting extremism and threats on social media. I have also worked on machine learning at Snap Inc., Siemens Healthineers, and Tokyo Electron.

Outside of research, I enjoy winter hiking and skiing across New England, playing piano, cooking, reading, and photography.
