My office hours are Mon/Thu 8:30–9:30 and Wed 9:30–10:30. If you're busy then, email me to schedule a time to meet. Or just stop by. This semester I'm teaching Calc II, FOM and Knot Theory. Click below for course info.

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.

Fall 2019: I'm teaching MATH152: Calculus II (Section 1: MWF 1:20–2:30 in Schaefer 109), MATH 281: Foundations of Mathematics (MWF 10:40–11:50 in Schaefer 134), and MATH 485: Knot Theory (TuTh 10–11:50 in Schaefer 132). Course syllabi and additional info is available in your course Google drive. Contact me ASAP if you don't have access.

Office Hours: Monday/Thursday 8:30–9:30, Wednesday 9:30–10:30.

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

Course description for MATH 485: Topics in Mathematics, Fall 2019
Knot Theory: Knots are familiar objects. Yet the mathematical theory of knots quickly leads to deep results in Topology and Geometry, as well as applications in Chemistry, Physics and Biology. At the same time, there are many accessible open problems suitable for undergraduate research. Prerequisites: MATH 256 and MATH 281.

My Research

image 04

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.
