Joseph A. Izatt

Biophotonics is concerned with the application of cutting-edge optoelectronic technologies to problems in the biomedical sciences. My research centers on the application of optical technologies for non-invasive, high-resolution imaging and sensing in living biological tissues. The technologies we use in my laboratory include acousto-optic and integrated-optic devices, femtosecond lasers, and ultrabroadband fiber optic telecommunications equipment. The applications of the systems we build include noninvasive medical diagnostics, in-vivo tomographic microscopes, and high-throughput three-dimensional small animal imaging systems for genomics studies. Our work involves multiple collaborations with engineers, biologists, and physicians at Duke and elsewhere.
