Associate Professor of Optics, The Institute of Optics, University of Rochester
Andrew Berger, Associate Professor of Optics, holds physics degrees from Yale (B.S., 1991) and MIT (Ph.D., 1998). He did his doctoral work developing methods of blood analysis using laser spectroscopy. Prior to coming to the Institute of Optics, he spent two years at the Beckman Laser Institute and Medical Center in Irvine, CA, building handheld systems to analyze breast tissue content.
Professor Berger's area of interest is biomedical optics, specifically spectroscopic diagnostic techniques. His group's present research is centered includes Raman spectroscopy of oral bacteria, single-cell Raman spectroscopy, multimodal microscopy (Raman plus elastic scatter), and near-infrared spectroscopy of hemodynamics in the human brain.
More generally, Professor Berger seeks to apply lasers and spectroscopic methods (absorption, fluorescence, Raman, and scattering spectroscopies) to problems of medical interest. As offshoots of this basic thrust, other interests include: (1) exploring fundamental aspects of light scattering and diffusion in turbid (e.g. biological) media; and (2) developing novel spectroscopic techniques, through both instrumentation and analytical modeling, that extend the range of biomedical phenomena which can be studied using light.
The proximity of the Institute of Optics to the Medical Center offers opportunities for close interaction with clinical collaborators and patients. Professor Berger also holds a secondary appointment in the department of Biomedical Engineering.
