I am an Assistant Professor in the Department of Computer Sciences at University of Wisconsin Madison. I have recently spent a wonderful year as a postdoc researcher in the Computer Science department at Stanford University, working with Chris Ré. Previously, I completed my PhD from Cornell University in 2017, where I was fortunate to be advised by John E. Hopcroft. My thesis committee members are Kilian Q. Weinberger and Thorsten Joachims. I've spent time at Google AI twice as an intern, and Facebook AI as a Research Scientist. I was named Forbes 30 Under 30 in Science in 2020.
My broad research interests are in deep learning and its applications. My time in both academia and industry has shaped my view and approach in research. The goal of my research is to enable transformative algorithms and practices towards trustworthy open-world machine learning, which can function safely and adaptively in the presence of evolving and unpredictable data stream. Our works explore, understand, and mitigate the many challenges where failure modes can occur in deploying machine learning models in the open world. Research topics that I am currently focusing on include:
[Joining the group]: I am looking for highly motivated students to join my group in the fall! The admission decision at CS department is committee based.
