Welcome! My office is in Schaefer Hall, room 172. Come by any time. If the door's open, you're not interrupting. You can also schedule an appointment.

Spring 2022
My student hours (office hours) are Mon/Wed/Fri 10–11. If you're busy then, email me to schedule a time to meet. Or just stop by. This semester I'll be teaching Discrete Math, Graph Theory and Abstract Algebra II. Click below for course info.
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. We host an NSF-funded REU! Other things!
Research
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.
My classes
Spring 2022: I'm teaching MATH200: Discrete Mathematics (MWF 12–1:10), MATH422: Abstract Algebra II (TR 10–11:50) and COSC455: Graph Theory (TR 2–3:50). Syllabi and additional info are available on Blackboard and your course Google drive. Contact me if you need access.
Open Student Hours (in person!): Monday/Wednesday/Friday 10–11am. If you're not free during my open hours, you can email me to schedule an appointment.
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.
Preprints
Some of my preprints can be found here. Links to all my papers (and publication info) are in my CV. Papers marked with an asterisk* are coauthored with one or more undergraduates.
• Derivatives of Jones Polynomials Detect Delta Moves*
• Reidemeister Moves in Gauss Diagrams*
• Virtual Mosaic Knot Theory
• Restrictions on Homflypt and Kauffman Polynomials*
• Knots with Composite Colors*
• Unoriented Links and the Jones Polynomial*
• Local Moves and Restrictions on the Jones Polynomial
• The Forbidden Number of a Knot
• TWIST UNTANGLE and Related Knot Games*
• UNTANGLE: Knots in Combinatorial Game Theory
• Chirality vs. HOMFLY and Kauffman Polynomials*

Infinity Licenses
Want to be able to use infinity without justification? Want to be able to say "Well, that's 1 over infinity so it goes to 0" without Alex demanding epsilons and deltas? Just pass your infinity exam and it can happen!
246
Every Friday at 2:46 there's a short (ends by 3:14) lecture on a topic not typically covered in any class. Usually if you've had FOM you know enough to enjoy it.
Klein Bottle Openers
Want one? Just declare your math major and it's yours! Fläche? Flasche? FYI, that's a Klein bottle on the shelf up there. I have one on the shelf in my office too. Stop by and take a look.
