Ruihan Wu (吴睿涵)

Hi! I am currently a fifth year Ph.D. candidate in Computer Science Department of Cornell University. I am very fortunate to be advised by Kilian Q. Weinberger. Before Cornell, I received my B.E. in computer science from Yao Class, Tsinghua University. My research recently focuses on studying privacy and security problems raised from ML algorithms and analyzing the test-time usage of models. Previously, I worked on several other topics such as learning theory, Gaussian processes and influence maximization.
