Al-Hafeez Z Dhalla


Assistant Research Professor in the Department of Biomedical Engineering

My research centers on the application of optical technologies for non-invasive, high-resolution imaging of biological tissues.  In particular, I focus on applications of optical coherence tomography (OCT) and scanning laser ophthalmoscopy (SLO) in the diagnosis and treatment of 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.
