I am a senior research engineer at Meta AI Research. My research interests include large-scale machine learning, federated and on-device learning, and differential privacy. I served as technical program committee for FL-ICML, FL-NeurIPS, and reviewer for ICLR, ICML, NeurIPS, AISTATS and MLSys.
Prior to Meta, I graduated Cum Laude from UC Davis with with double majors in Statistics and Computer Science (2018) and M.S in Computer Science (2019). At UC Davis, I worked with Prem Devanbu and Vincent Hellendoorn on empirical software engineering.
