I am a Ph.D. student in the Manning College of Information & Computer Sciences at UMass Amherst, advised by Amir Houmansadr. My research focuses on privacy and security in machine learning. I previously worked with Gerome Miklau on differential privacy. Before that, I received my B.S. from Waseda University in Japan.
I have also interned at Oracle Labs and Meta on privacy-enhancing technologies.
