Recent Math Talks

Counting Liars and Truth-tellers - from the 2012 Joint Mathematics Meeting

Teaching:

This Spring (2012) I will teach two sections for Discrete Mathematics and one of Introduction to Modern Geometry. Course materials will be available through Blackboard.

I have begun recording videos where I work out some example problems. These can be seen on the relevant course pages, or on my YouTube channel: Mathematics Exemplified.

Last Fall, I tought Discrete Mathematics and Topics in Calculus here at UNC. I have tought a wide variety of courses at Coastal Carolina University and the University of Connecticut as well. Course websites for most of those classes are available here.

Research

My primary interests lie in effective algebra, computability theory, reverse mathematics, and mathematical logic. Effective algebra endeavors to understand results of algebra and combinatorics from a viewpoint of computability theory. My Ph.D. dissertation concerns the effective content of ordered fields. My thesis, along with some other papers I've worked on, are available on my research page

Mathematical Puzzles

I am a big proponent of using mathematical puzzles in teaching. I have started a collection of the best of these puzzles on what I'm calling the Math Puzzle Wiki. If you are a math teacher looking for a good extra credit problem, or simply a puzzle enthusiast, please check it out. You can even contribute your own puzzles or add to ones already there.

LaTeX

Thanks to jsMath, the following should look like math, and not code: $\exists c \in (a,b) \left(f'(c) = \frac{f(b) - f(a)}{b-a}\right)$
