Eric has since moved on and is currently working in the Anna Lin Group at Duke University. Eric was a tremendous asset to the lab and was instrumental in the devolpment of many students during his time with the Kopelman group. His presence in the lab will truly be missed. Thanks Eric!!

Background: My undergraduate training was in Physics with some Electrical Engineering at MIT, while my graduate work was in Applied Physics here at the U of M, conducting research through both the Biophysics Research Division and the Chemistry department.

Current Research: At this moment, the focus of my work is the experimental realization of non-classical, diffusion-limited reaction kinetics results, specifically the binary A+B->0 (or C) system. This type of reaction would seem simple, and therefore well understood, but diffusion is such an inefficient transport mechanism (especially in low-dimensions) that there are many dramatic deviations from the classical textbook treatment of the problem. [See the Physical Chemistry section for more detailed info!] The trick, though, in experiments is to find a system in which the interesting behaviors are not masked from detection by other competing effects.
The model system I've been using is the complex formation between a calcium ion and a calcium sensitive fluorophore. In this case, the calcium ion is initially bound to a "cage" molecule, and then released for reaction by a pulse of near-UV light. The kinetic rates and initial spatial distribution effects can then be followed by monitoring the fluorescence of the dye over time.
In addition to this work, I also supply technical support to other projects in the group. My recent research has also involved various forms of fluorescence imaging, Near-Field Scanning Optical Microscopy, sensor dynamics and fluorescence correlation spectroscopy, as well as simulation work and wavelet analysis of anomalous reaction kinetics systems.
