About Me

Hello! I am a Computer Science Ph.D. candidate at Cornell University (physically located at Cornell Tech) working with Prof. Vitaly Shmatikov. My current research interests are security & privacy issues in machine learning. I completed my bachelor's degree at Emory University, where I worked closely with Prof. Ymir Vigfusson and Prof. Lee Cooper on some fun real world deep learning application projects.


Research intern at Google Brain, August 2019 - December 2019
Research intern at Petuum Inc, May 2019 - August 2019
