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 Math 256: Linear Algebra (MWF 1:20–2:30 in Schaefer 134) and Math321: Algebra (MWF 12–1:10 in Schaefer 109).

Spring 2015 classes have not been chosen yet. Times, days, locations, textbooks and other information will be posted here as it becomes 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 the subject of Topology. Within this field, 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.


Recent 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.

• New Bounds for Forbidden Numbers of Knots (E. Lehet*, C. Lopez*, G. Magallon*, and A. Thompson*).
Local Moves and Restrictions on the Jones Polynomial.
The Forbidden Number of a Knot (A. Crans and B. Mellor).
TWIST UNTANGLE and Related Knot Games (A. Meadows and J. Ross*).
UNTANGLE: Knots in Combinatorial Game Theory (A. Meadows).
Chirality vs. HOMFLY and Kauffman Polynomials (A. Kapp*).
Ends of 4-Manifolds.
