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 have an affiliate appointment in the Department of Statistics and I am also affiliated with the Theory of Computing Group in the Department of Computer Sciences. I can often be found at the Wisconsin Institute for Discovery.
I am on the executive committee of the Institute for Foundations of Data Science (IFDS), a collaboration with the University of Washington, the University of California, Santa Cruz, and the University of Chicago, funded through the NSF TRIPODS Phase II program.
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-2023239 (TRIPODS Phase II) and DMS-2308495. My CV is here.
Aug 2023: I have a new NSF grant.
May 2023: My Ph.D. student Yu Sun successfully defended his thesis. Congratulations!
Jan 2023: My Ph.D. student Shuqi Yu successfully defended her thesis. Congratulations!
Jul 2022: Our proposal for a semester-long program on Meeting the Genomics Data Challenge: Theory, Methods, and Applications of Quantitative Phylogenomics at the Institute for Computational and Experimental Research in Mathematics (ICERM) has been approved. The program (led by Elizabeth Allman and Laura Kubatko) will take place Fall 2024. More details to come.
Apr 2022: I was named Fellow of the Institute of Mathematical Statistics (IMS).
Apr 2022: This Spring, I have been mentoring an amazing team of undergraduate students through the Madison Experimental Mathematics Lab. They will present their project, entitled Shedding Light on Unexplained Behavior of Phylogeny Estimation Methods, at an open house on Tuesday, May 3 from 2-5pm in Van Vleck 911 (the 9th floor lounge).
Feb 2022: I am on the Program Committee of WABI 2022: Workshop on Algorithms in Bioinformatics. The submission deadline is May 18, 2022.
Dec 2021: Our proposal for a month-long program on Mathematics of Evolution-Phylogenetic Trees and Networks at the Institute for Mathematical Sciences (IMS) of the National University of Singapore (NUS) has been funded. The program (led by Louxin Zhang and Daniel Huson) will take place 5 Sep 2023 to 29 Sep 2023. More details to come.
Aug 2021: I will teach the newly created graduate course MATH/ECE/STAT 888 - Topics in Mathematical Data Science this Fall for the first time. The topic in Fall 2021 is "High-Dimensional Probability and Statistics: Non-Asymptotic Theory."
