With a PhD in physics, Santiago Costantino is the director of the Biophotonics Research Unit. Santiago Costantino’s biophysics work is based on biomedical research applications of the science of lasers and microscopy. He is also an associate professor in the Department of Ophthalmology at Université de Montréal.
Our laboratory specializes in biophotonics, which is at the intersection between biology and optical physics. Our projects are varied but focus on two main areas: 1) surface or membrane functionalization and 2) optical coherence tomography (OCT) of the retina. We specialize in image analysis in both areas. Our team is a successful mix of biologists, physicists, engineers and eye specialists.
In microscopy, we are developing methods to visualize and develop artificial microenvironments for applications in cell biology. We manufacture protein patterns for cell guidance using optical methods, and we are working to develop cellular nanosurgery on axons.
In macroscopy, we are working on femtosecond laser applications for eye surgery. We are developing methods to improve the spatial accuracy of laser dissection and optimize the parameters of the femtosecond lasers used in corneal transplantation.
