I'm a professor in the Department of Physics and Astronomy at the University of Pennsylvania . I'm also affiliated with the Laboratory for Research on the Structure of Matter. I was educated at the University of California at Santa Barbara in the College of Creative Studies, and at the Massachusetts Institute of Technology. (Check out my resume for more details. I also have a boring but more-official-looking home page in the Physics Department). The picture above illustrates some of my recent research interests: dendrimers (left picture), colloids (center picture), liquid crystals (right picture). My primary research tool is x-ray scattering. Over the years I've gotten my name on a bunch of papers. Together with Karen Winey I am responsible for the Multiple-Angle X-ray Scattering (MAXS) facility, and I am the one to contact if you wish to schedule time on this instrument.
I live in Upper Merion, which is outside of Philadelphia, Pennsylvania. My father published numerous novels and short stories under the pseudonym of MacDonald Harris.
In my (limited) spare time I write letters for Amnesty International. I'm interested in geneaology in general and have compiled some notes on my own family's history. If you want you can look at my list of frequently accessed bookmarks.
There are several other people on the web with the same name as me. Notably, there is a well-known Paul Heiney who appears frequently on the BBC and is an author of many books, many having to do with farming.
