Math riddles

Here are some of my favorite math riddles.


I help organize the Online Seminar for the Applied Algebraic Topology Research Network. Recordings of our seminar are available at our YouTube Channel.

At Colorado State University, I co-organize the Putnam Semniar, co-organize the Applied Topology Seminar, am a member of the Pattern Analysis Lab, and attend the Algebraic Combinatorics Seminar and the Data Science Seminar. In 2011-2013 I organized Stanford's Computational Topology Reading Group.
