Fall 2014

My fall 2014 office hours are Monday, Wednesday, Friday 9–10. If you're busy then, email me to schedule a time to meet. This semester I'm teaching Linear Algebra (MATH256, MWF 1:20–2:30) and Algebra (MATH321, MWF 12–1:10).

Math/CS Department

Here's some of what's happening in the department.

You can take an exam to get your infinity license! There's a 246 lecture at, um, 2:46. Also, Bling! Math club! CS Co-op! Putnam exam! Other things!


My main area of research is Geometric Topology, specifically 4-Manifolds and Knot Theory. I'm also interested in Geometric Group Theory and Combinatorial Games.

Fall 2014: I'm teaching MATH256: Linear Algebra (MWF 1:20–2:30 in Schaefer 134) and MATH321: Algebra I (MWF 12–1:10 in Schaefer 109). The textbook for Algebra will be Abstract Algebra, Third Edition, by Dummit and Foote. Note that this is a change in textbook from last year.

Spring 2015: I'll be teaching MATH151 (Calc I), MATH281 (FOM), and MATH322 (Algebra II). Times, days, locations, textbooks and other information will be posted here when available.

My past courses (taught at SMCM, University of The Gambia, Pomona College and Rice University) are listed in my CV.

My Research

My primary interest in mathematics is in Geometric Topology. More specifically, my research focusses on Knot Theory and the Topology of 4-Manifolds. I'm also interested in Geometric Group Theory and Combinatorial Game Theory.

Students interested in doing research (or SMPs) in any of these areas should read (or at least skim) the linked Wikipedia pages and come see me. A course in Topology is helpful (but not essential) for studying Knot Theory. Algebra I is essential for studying Geometric Group Theory; Topology and Algebra II are essential for studying 4-manifolds.


Some of my preprints can be found here. Links to all my papers (and publication info) are in my CV. Coauthors marked with an asterisk* were undergraduates when the research was conducted.
