Department of Chemistry, Ursinus College, Collegeville, PA  19426

I am a physical chemist here at Ursinus College. I joined the faculty in August 2005. I was previously the physical chemist at Wittenberg University.  Here is a picture of me having fun with chemistry!


Here is my academic family tree. I can trace my "academic family" back to the 1400s!

Here is a link to a movie (1.1Mb) that shows the force of an expanding gas. If you think P Chem isn't any fun, click here.

So long, and thanks for all the fish!

Vitae and Publications

Research Interests

My research interests are in the areas of the chemistry of surfaces and materials. Specifically, I am interested in using chemistry to design electrical and optical properties of materials.

Adsorption of Gases on Carbon Nanotubes
Carbon nanotubes have a wide array of interesting mechanical and electrical properties. We are studying the adsorption of gases on nanotubes and how the adsorption changes the electrical properties of the nanotubes.

This research has been supported by a Cottrell College Science Award from the Research Corporation.

Attachment of Organic Layers to Silicon
Silicon is the basis of nearly all technology, from transistors to integrated circuits to to computer CPUs. We use infrared spectroscopy (FTIR) and a scanning tunneling microscope (STM) to study silicon surfaces. Click here to see some of the images students have collected.
