My research interest is in development of optical technologies for biomedical applications. My lab is developing is flexible fiber- optic implantable miniature microscopes using two-photon microscopy. The applications of these devices include better understanding of the function of brain or peripheral networks by imaging and photo-stimulating neurons rapidly in a full 3D volume. The goal is to study brain networks in freely moving animals undergoing complex behavior tasks. Additionally, I have been working under the NIH SPARC initiative to develop these miniature microscopes to image and photo-stimulate axons in the vagus nerve through a nerve cuff. Another application is use of the miniature microscope for label-free imaging in endoscopy applications. Other work in my lab includes development of a custom superresolution STimulated Emission Depletion (STED) microscope to image live cells at sub-100 nm resolution at video rates to visualize dynamics of protein localization or structural changes in vivo.
