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.
