In this course we develop an adult-level
perspective and insight into the nature of mathematics taught in
elementary school. In 140 we focus on number. Our two themes
for this course are the nature of mathematics and the practice of
problem solving (the act of doing mathematics). Students
often work together to develop and deepen their understanding of the
mathematical concepts. Frequently this involves the use of
manipulatives to incorporate a tangible explanation for the methods
studied. This course is the next step toward a career of explaining
concepts (here mathematics) that you have taken for granted
before.
I will assume that university students do
not need to be taught elementary school mathematics. We will not
be reviewing, but rather justifying that material. For a
reference on the content of elementary school mathematics, here is the Common
Core Standards for Mathematics.
MATHEMATICS 315
Combinatorics
MWF 10:30 - 11:20a: Sturges 104
Prerequisites: MATH 222, 233, and either 237 or 239
The purpose of this class is to solve a
variety of diverse discrete and counting problems.
MATHEMATICS 338
Topology
MW 4:00 - 5:15p: Sturges 105
Prerequisites: MATH 223, MATH 239
Topology can be divided into three main
areas: general, geometric, and algebraic. General topology
is the study of sets with a defined “closeness”. Geometric
topology is the study of the shapes that are unchanged under
stretching. Algebraic topology is the study of algebraic objects
that arise from topological objects, or the study of topological objects
using algebra.

Professional Activities
I am an active member of the Mathematical Association of America. In
particular, I am the liaison coordinator and the co-chair of the Program
Committee for the Seaway Section. I am also a member of the American
Mathematical Society.
Areas of research
- Low-dimensional Topology
- Knots, Links, and 3-manifolds
Current projects
I am currently pursuing several research projects. The newest of the
projects is an exploration of the role of Euclid's Fourth Postulate:
"All right angles are equal." The older of these projects
consists of investigating how the Casson-Walker-Lescop 3-manifold
invariant changes when modifying the presenting link for a 3-manifold.
This project has evolved into studying questions of the Ohtsuki invariants
of rational homology spheres, and questions of the space of finite type
invariants for links of three or more components. Another long-term
project is to study symmetries of links. In particular I am
examining a refinement of unlinking number accounting for which components
are involved in each of the crossing changes, a so-called coloured
unlinking number. Finally, I am examining comparisons and connections
between mathematician Evariste Galois and composer Hector Berlioz.
