Xinyu Tang

I work on machine learning and privacy at Apple.

I received Ph.D. from Princeton University advised by Prof. Prateek Mittal. My dissertation was "Effectively Learning From Data and Generating Data in Differentially Private Machine Learning".

I obtained a Bachelor's degree from University of Science and Technology of China (USTC) in 2019.
