Photon mayhem: Using light for structural and functional assessment of biological tissues


Speaker: Prof. Alex Vitkin
University of Toronto
SPIE Visiting Lecture series

Time: Monday, December 18, 11am-12pm
Location: 400 Cory Hall

Abstract:
Medicinal photonics (biophotonics) includes a variety of therapeutic (effects of light on tissue) and diagnostic (effects of tissue on light) applications. In this talk, the latter category will be highlighted, with emphasis on methods actively investigated in our laboratory – optical coherence tomography for microvascular imaging and tissue polarimetry for anisotropy monitoring. Both of these approaches rely on the wave nature of light (coherence and polarization, respectively) and offer unique biophysical information on tissue structure, composition, and function.

Speaker bio:
Alex Vitkin is a professor of Medical Biophysics and Radiation Oncology at the University of Toronto, a senior scientist at the University Health Network, and a board-certified clinical medical physicist at Princess Margaret Cancer Centre (all in Toronto, Canada). He has published ~180 papers and book chapters on biophotonics, specializing in tissue polarimetry, microvascular / multi-functional optical coherence tomography, and optical fiber sensors. His research ranges from basic photonics and biophysics, to biomedical optics and bio-engineering and pre-clinical experimentation, thru to clinical translation. He serves on several national and international research grant panels, and is involved in organizing / chairing international biophotonics conferences. He is the recipient of the 2017 Michael S. Patterson Publication Impact Prize in Medical Physics, awarded by the Canadian Organization of Medical Physicists. Dr. Vitkin is also a topical editor of Optics Letters, a Fellow of OSA and SPIE, and a visiting professor at the Nizhny Novgorod State Medical Academy (Russia).
