Spring 2015

My spring 2015 office hours are Monday, Wednesday, Friday 10:30–11:30. If you're busy then, email me to schedule a time to meet. Or just stop by. This semester I'm teaching Calc I (MATH 151), FOM (MATH 281) and Algebra II (MATH322).

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.

Spring 2015: I'm teaching MATH151: Calculus I (MWF 1:20–2:30 in Schaefer 132), MATH281: FOM (MWF 9:20–10:30 in Schaefer 161) and MATH322: Algebra II (MWF 12–1:10 in Schaefer 109). The textbook for FOM will be Book of Proof, Second Edition, by Richard Hammack. It is available for free here as a pdf, or you can buy the book from the bookstore or online for about $14. For Algebra we will continue to use Dummit and Foote. There's also that Advanced Linear Algebra Seminar.

Fall 2016: Courses, 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.
