I am a musculoskeletal radiology fellow at NYU.
Prior to this, I completed medical school at Mount Sinai, a preliminary medicine year at California Pacific Medical Center, and radiology residency at Columbia. Before medicine, I worked in investment management and completed a master’s degree in Statistics at Columbia.
I am working to understand how we can apply machine learning to create effective clinical decision support in radiology.
