I am a Data Science Ph.D. student at UC San Diego, where I am extremely fortunate to be advised by Prof. Yu-Xiang Wang and to work closely with Prof. Yi-An Ma

My research focuses on differential privacy and machine learning, from theory to practice. Recently, I have being thinking how tecniques from differential privacy can address safety concerns in generative models.
