#### Teaching Statement

I love to teach. As an instructor, I set high standards, and then commit myself to serving you with whatever means necessary to help you meet those standards.

#### Videos

You can see some of the videos I have made. More are available on my YouTube channel and at iTunes U.

#### Office hours

My office is room MW610 in the Math Tower, and I offer Zoom office hours.

### Calculus One

Calculus is about the very large, the very small, and how things change. The surprise is that something seemingly so abstract ends up explaining the real world. Calculus plays a starring role in the biological, physical, and social sciences. This online course is a first and friendly introduction to calculus, suitable for someone who has never seen the subject before, or for someone who has seen some calculus but wants to review the concepts and practice applying those concepts to solve problems.

# Math 5801: General Topology and Knot Theory

In topology, we study geometric objects with an emphasis not so much on the size of things, but rather on those properties of spaces which are preserved under continuous deformations.

In this course in particular, we focus on:

**general topology**or “point-set topology” which establishes the foundations of metric spaces and topological spaces and the so-called big C’s of continuity, convergence, connected- ness, compactness, countability; and**knot theory**which studies embeddings of circles in three-dimensional space through com- binatorial, geometric, and algebraic techniques and invariants.

This course is a *fast-moving* journey through point-set topology, suitable for someone who has had some experience with a proof-based math course and is ready to dive into some naïve set theory today.
