PLEASE NOTE - I have moved!
Starting in Fall'07 I joined faculty at the University of California, San Diego in the Physics Department.

My new contact info is:
Phone: 858.952.1248

What's New:
  • Magnetic Speckle paper published in Nature (May 2007)
  • Hall Effect & Microscopy of AFM Domains published in PRL (Mar. 2007)
  • Nanopore capillary filling work is published in PRL (Oct. 2006)
  • Surface Freezing work is published in Science (July 2006)
  • Demixing in binary alloys is published in PRL (Sep. 2005)
  • In the Media:
  • X-ray holograms expose secret magnetism (May 2007)
  • Liquid alloy shows solid-like crystal structure at surface and NSLS Highlights (July 2006)
  • Demixing in BiSn is featured in APS Highlights (May 2006)
  • Mixed Metals not so Mixed Up at the Nano Level, in Argonne News (Dec 2005)

    What's Not so New: Over the past several years David Morin and I have been organizing an Undergraduate Physics Competition: 4 hours to solve 6 challenging physics problems, held in late April simultaneously at a dozen or so locations across US and abroad. Here's past editions.
