About Me

I'm a first-year PhD student in the Center for Systems Science and Engineering at Johns Hopkins University. My primary research interests are in optimization and machine learning, particularly for applications in healthcare and medicine. I recently graduated with a BS in Computer Science and Applied Math from Johns Hopkins.
