In addition, he also holds adjunct appointments of the Departments of Bioengineering, Physiology and Biophysics, and Medicine at the University. His research interests focus on applying and developing advanced optical imaging and spectroscopic techniques to study important biomedical problems. Several projects that he is currently researching include: 1) developing nonlinear imaging techniques for early glaucoma detection and diagnostics, 2) measuring protein dynamics and interactions using fluorescent correlation techniques in cell membranes and in lipid rafts for renal diseases, and 3) determining the optical scattering properties of brain tissue to understanding neural circuitry functions using optogenetic proteins.
