Congzheng Song is a Computer Science Ph.D candidate at Cornell University working with Prof. Vitaly Shmatikov. His research interests are in security and privacy in machine learning. His past works identified a range of privacy leakages, either intentionally or unintentionally, when training and deploying machine learning models computed on sensitive user data. As a DLI fellow, Congzheng will continue exploring and identifying security and privacy threats in real world artificial intelligence assisted systems.
