I am a Professor in the Department of Mathematics at the University of Wisconsin-Madison, where I belong to the Probability Group and Applied Mathematics Group. I am also a member of the Institute for Foundations of Data Science (IFDS), I have an affiliate appointment in the Department of Statistics and I am affiliated with the Theory of Computing Group in the Department of Computer Sciences. I can also be found at the Wisconsin Institute for Discovery. My CV is 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-1614242, CCF-1740707 (TRIPODS), DMS-1902892, and DMS-1916378, as well as a Simons Fellowship and a Vilas Associates Award.
