Our research efforts include a wide range of topics including materials synthesis, integrated optics and instrumentation development, and characterization of tissue and disease diagnostics. We also perform a significant amount of computational work to support our experimental efforts. Given the diversity of measurements, we perform experiments on the main campus and at the medical school.
To enable this research breadth, our group members include researchers with diverse academic and research backgrounds, and we have numerous ongoing collaborations, both at USC and at other institutions around the world. The lab also supports a large number of undergraduate researchers as well as high school researchers. We are also very active in a wide range of STEM outreach activities. Financial support comes from several different agencies and companies as well as philanthropic contributions.
The lab is primarily located in the Viterbi School of Engineering, and it is affiliated (through courtesy appointments in different depts and institutes) with the Dornsife College and the Keck Medical School. The research facilities are located in the newly constructed Michelson Center for Convergent Biosciences.
