I am a Professor in the Department of Mathematics at the University of Wisconsin-Madison, where I am affiliated with the Probability Group and the Applied Mathematics Group. I am also involved with the Institute for Foundations of Data Science (IFDS). My CV can be found here.

I work at the intersection of applied probability, statistics and theoretical computer science, with an emphasis on biological applications. More details on my research interests and publications can be found here. My work is currently supported by NSF grants DMS-1149312 (CAREER), DMS-1614242 and CCF-1740707 (TRIPODS).

I am an associate editor for the Annals of Applied Probability. Submit a paper here.


Apr 2018: Best Paper Award - My paper "Circular Networks from Distorted Metrics" with former Ph.D. student Jason Wang won Best Paper Award at RECOMB 2018.

Apr 2018: TRIPODS Summer School on Fundamentals of Data Analysis - The Institute for Foundations of Data Science at UW-Madison, in collaboration with the NSF TRIPODS Institutes at the University of Washington and at the University of California-Berkeley, is organizing a summer school on July 24-28, 2018 in Madison. Apply by April 20 here.

Mar 2018: Simons Fellowship - I am grateful to the Simons Foundation for supporting my upcoming sabbatical (2018-2019) through a Simons Fellowship.

Jan 2018: Honorable Mention - My paper with Mike Steel on "Likelihood-based tree reconstruction on a concatenation of aligned sequence data sets can be statistically inconsistent" received Honorable Mention in the 2018 Marcus W. Feldman Prize in Theoretical Population Biology.

Aug 2017: New Data Science Institute - Our new Institute for Foundations of Data Science has been funded through the NSF TRIPODS and NSF Growing Convergence Research programs. More details here and here. The website of IFDS is here.
