About / CV
I am currently an MD PhD student at Mount Sinai's Medical Scientist Training Program (MSTP) and a postdoctoral fellow at NYU School of Medicine. I will begin my radiology residency at NYU in 2024. I got my bachelor and master of science in engineering at the University of Pennsylvania before coming to New York. I was born in Seoul, South Korea and grew up in Toronto, Canada and Auburn, Alabama.
My goal is to become an academic radiologist and improve accessibility of machine learning and imaging techniques. I have research experiences in molecular imaging, radiation physics, computer vision, and artificial intelligence. I have been published in NeurIPS Proceedings (PMLR), Radiology: Artificial Intelligence (cover article Volume 3 Issue 2), Nature Medicine, Pediatrics, and more.
Clinically, I have worked as a certified EMT and a senior clinician in a student run, physician supervised clinic at Mount Sinai. Working with underserved communities inspired me to research methods to expand availability of radiology resources to all patients.
I fell in love with radiology, an exceptional intersection of technology and medicine, during a signals course lecture given by Andrew Maidment at The University of Pennsylvania. I completed my senior design project with him and developed methods to quantify and incorporate super resolution in digital breast tomosynthesis. I completed my master's thesis with Marni Falk at The Children's Hospital of Philadelphia and developed a technique to automate quantitation of fluorescent markers of mitochondrial physiology.
During my PhD training with Anthony Costa and Eric Oermann at Mount Sinai, I focused on developing an objective, quantitative metric to evaluate diagnostic utility of generative ML algorithms. I was part of an international federated learning project to improve the generalizability of a COVID-19 prognostication algorithm. I am continuing to work with Eric as a postdoc at the NYU OLAB to build standardized radiology datasets and create additional federated learning collaborations.
