Spring 2018

My Spring 2018 office hours are Monday, Wednesday, Friday 12–1. If you're busy then, email me to schedule a time to meet. Or just stop by. This semester I'm teaching Discrete Math (MATH 200) and Abstract Algebra II (MATH 422). Course info is on Blackboard.

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. We host an NSF-funded REU! 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.

Spring 2018: I'm teaching MATH 422: Abstract Algebra II (Section 1 meets Tu/Th 12–1:50; section 2 meets Tu/Th 2–3:50, both in Schaefer 109) and MATH 200: Discrete Math (MWF 1:20–2:30 in Schaefer 132).

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. Abstract Algebra I is essential for studying Geometric Group Theory; both Topology and Abstract 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.
