I am a Professor of Mathematics at Temple University, as you have probably already guessed. My research interests include geometry, topology, group theory, probability, number theory, physical chemistry, bio chemistry, symbolic and otherwise computation, finance, and most everything else.
I am running (jointly with David Futer) the Temple Geometry Seminar, more info on which (as well as many other things, including my comings and goings) on the Temple Geometry Blog.
You can find the almost correct list of my publications and citations thereto on Google Citations, and my (usually almost) current CV here.
I am a frequent contributor to MathUndertowOverflow.
I am an editor of Geometriae Dedicata.
Some of my presentations (and those of my collaborators) are recorded for posterity on Slideshare.

This term (Spring 2012) I am teaching two courses: Mathematical Patterns (Math 0824) and Senior Problem Solving Seminar (Math 6451).
