James Chan

James Chan received a B.S. in Chemical Engineering in 1997 from the University of California, Berkeley and a Ph.D. in Chemical Engineering from the University of California, Davis in 2002, where he studied the interaction mechanism of ultrashort laser pulses using a combination of Raman and fluorescence spectroscopy/microscopy.

Dr. Chan held postdoctoral position at Lawrence Livermore National Laboratory (LLNL) in the Medical Physics and Biophysics Division, where he developed Raman spectroscopy methods for single cell analysis for a broad range of biomedical applications. He then became a LLNL staff scientist from 2005-2010 where he continued his biophotonics research jointly with the NSF Center for Biophotonics at UC Davis. At LLNL, he was also involved in research developing optical sensors for chemical sensing applications.

In 2011, he joined the research faculty in the Department of Pathology and Laboratory Medicine at the University of California, Davis, where his research focus was on developing optical spectroscopy and microscopy methods (Raman, fluorescence, nonlinear optics) for biological and biomedical imaging.

Dr. Chan has co-authored over 60 publications in refereed science journals and several book chapters.
