Yutao Zhong

I am a PhD student in Mathematics at the Courant Institute, New York University. I am fortunate to be advised by Prof. Mehryar Mohri and work closely with Corinna Cortes. I have also had the opportunity to collaborate with, or be mentored by, several research scientists at Google Research during my internships, including Pranjal Awasthi, Raef Bassily, Christoph Dann, Javier Gonzalvo, Satyen Kale, Teodor Marinov, Dmitry Storcheus, Ananda Theertha Suresh, Julian Zimmert, etc.

My main area of research is learning theory, and in particular in the last few years, I have worked on the following topics: consistency theory and guarantees, adversarial robustness, active learning, learning with abstentions, learning to defer, structured prediction, ranking, etc. While I am interested in theory, I am also strongly interested in designing algorithms with good theoretical guarantees.

I have also been fortunate to spend a fair amount of time as a research intern/student researcher at Google Research. This experience has given me the opportunity to work on large-scale problems for which I have derived enhanced and improved algorithmic solutions that I have fully implemented and experimented with. My goal is to use theoretical insights to develop principled and practical algorithms that can handle real-world problems.
