News: I am now working at Grinnell College. My website has moved!

I am a graduate student in the department of Mathematics at Purdue University, in my last year. I received my B.A. from Concordia College in 2012 with degrees in Math and Computer Science. I work with David Gleich. My current research interests include Network Analysis, Graph Modeling, and Numerical Linear Algebra problems broadly.

    The Purdue University Numerical Linear Algebra Group records all of its talks and uploads them to YouTube. Most of the talks I give in this seminar are related to my research, usually a fun tool or trick which I would like to share with the group. Other times I present a paper or topic that interests me, that I am still just learning about. Here are those talks.

    Hodge Laplacians on Graphs, Spring 2018
    Memory Efficient Generation of Q from Householder QR, Spring 2017
    Optimality of Krylov Information, Spring 2016
    Introduction to the Fast Multipole Method, Spring 2015


    In the spring of 2016 I won the Purdue Teaching Academy Graduate Teaching Award. In the fall of 2015 I won the Purdue Math Department's Excellence in Teaching Award.
