Office: Cushing 227B


Ph.D., Stanford University, 2011

M.S. EE, Stanford University, 2007

B.S. EE, Northwestern University, 2005


Prof. O'Sullivan received a B.S. in Electrical Engineering from Northwestern University in 2005, and received a M.S. and Ph.D. in Electrical Engineering from Stanford University in 2007 and 2011, respectively. After graduation he studied as a postdoctoral fellow at the University of California-Irvine Beckman Laser Institute in an NIH T32 Training Program in cancer biology, and later as a Department of Defense Breast Cancer Research Program Postdoctoral Fellow. Prof. O'Sullivan possesses expertise in semiconductor optical devices (lasers, photodetectors, and integrated optics) and semiconductor physics, with specific research interests in biomedical optical sensing and imaging. He was previously Director of the Diffuse Optical Spectroscopy and Imaging Laboratory at the UC Irvine Beckman Laser Institute, where he applied his unique background in engineering and cancer biology to develop quantitative approaches to advance basic scientific and clinical research in breast cancer. Prof. O'Sullivan has received several awards and grants, actively publishes his work in leading biomedical optics and engineering journals, and frequently presents his research at international conferences.
