Dhalla

Assistant Research Professor in the Department of Biomedical Engineering

My research focuses on the application of optical technologies for non-invasive, high-resolution imaging of biological tissues.  In particular, our laboratory develops optical coherence tomography (OCT), scanning laser ophthalmoscopy (SLO), light detection and ranging (LiDAR) and other optical imaging technologies for applications in the diagnosis and treatment of disease, particularly diseases of the eye. My work focuses not only on the engineering and technical development of novel imaging technologies, but also the preparation of these technologies for commercialization through clinical validation and regulatory approval.
