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.
