Bio-photonics is a line of research that encompasses multiple disciplines, including physics, mathematics, biology, and engineering. The Medical Photonics Laboratory (MPL) at FIU conducts research in bio-photonics and focuses particularly on the development of devices and methodologies for diagnosis of disease. We focus on the detection of early signs of Diabetic Retinopathy, a disease associated with diabetes, using spectroscopic and polarimetric techniques. We are also developing methodologies for non-invasive monitoring of the skin. We are conducting research on the discrimination of melanoma, one of the most dangerous forms of skin cancer, and we are seeking insights into several forms of skin damage including pressure damage, thermal damage, and electrical damage.
