Research
in Experimental Condensed Matter Physics and Nanotechnology
My background is in materials science, solid state physics and laser spectroscopy.
I do applied physics, that is physics that has applications to
some technology.
My research interests are in the very broad fields of optics and photonics. Some of our recent work has been on characterizing point defects in optical materials.
We are currently working on nanostructured fast optical switching devices. This is work done in collaboration with Vaibhav Jain and Randy Heflin at Virginia Tech.

Undergraduate
Research at Sweet Briar
I welcome student interest in working on various
projects with me. Student researchers have worked with me during the summer
and also during the academic year. A variety of funds are generally available
to fund undergraduate researchers at Sweet Briar (Honors Summer Research
Program, VFIC).
If you are interested in discussing project
ideas, please stop by my office or drop me an email.
Undergraduate researchers
from my lab have presented their results at regional (MARCUS) and national
conferences (APS-Los Angeles, APS-Montreal, Canada).

Our
Experimental Capabilities
Interested in doing research or using our laser system for collaborative
work ? If you are interesting in collaboration, here are the labs
current capabilities:
Nd:YAG or OPO excitation with ~10-100 mJ pulses, ~5 ns pulse width at
266 nm, 355 nm, & 420 nm - 2300 nm.
Closed Cycle Helium Refrigerator for optical measurements down
to 10 K
Emission spectra measurement with monochromator/PMT for lifetimes in the
ns to ms.I am currently collaborating with Dr. Donats Millers, Dr. Larisa
Grigojeva and Dr. Vladimir Pankratov at the Institute
of Solid State Physics in Riga, Latvia.
