Prof. Andrew J. Berger

Andrew Berger, Associate Professor of Optics, joined the faculty in July, 2000. Born in Boston and raised in Lexington, Massachusetts, he attended college at Yale and returned to the Boston area for graduate school at MIT, where his advisor was Michael Feld, Director of the Harrison Spectroscopy Laboratory . After graduate school, Prof. Berger spent two years as a Hewitt Research Fellow at the Beckman Laser Institute and Medical Center, University of California at Irvine, under the tutelage of Bruce Tromberg. Prof. Berger's research interests include near-infrared Raman spectroscopy of oral bacteria, Raman- and angular scattering by single immune cells, algorithms for converting spectroscopic data to concentration predictions, and photon-migration spectroscopy of brain activity.

Away from the lab, Prof. Berger can often be found playing ultimate frisbee or keeping remarkably careful track of the Boston Red Sox...at least, that is, when he isn't running after his two kids.
