Fire restoration work is expected to continue into late August. The main stairwell and office wing on both second and third floors of the Physics building will be closed until necessary repairs to the main stairwell are completed.
Administrative offices have been relocated to PHY 345.
Please contact individual faculty members to request appointments, as many faculty have been relocated during this process.
Please do not cross any caution tapes whilst in the building.
Dr. Bizheva's research focuses on the development of novel optical imaging technology (Optical Coherence Tomography - OCT) that can be used in clinics to image various part of the human body for diagnostic purposes or for monitoring the outcome of drug therapy or surgery.
Imaging with the OCT technology is non-contact, non-invasive and some of its medical applications include the diagnosis of potentially blinding diseases such as glaucoma, diabetic retinopathy or macular degeneration, screening for skin or oral cancer, or monitoring of surgical procedures such as retinal, corneal, heart and brain surgery.
Compared to commercially available OCT systems, the OCT technology developed in Dr. Bizheva's lab provides ultrahigh resolution in biological tissue sufficient to observe its cellular structure and the smallest blood vessels. Dr. Bizheva's research group has extensive and successful collaborations with Canadian and international industrial partners, as well as clinical collaborators with multiple hospitals in the Greater Toronto Area.

Dr. Bizheva's primary research contributions include: a) technological development of ultrahigh resolution OCT (UHROCT) to allow for imaging of sub-cellular details in living biological tissue; b) novel biomedical applications of UHROCT, for example in ophthalmology and neuroscience; c) computer modeling of light interaction with biological cells; and d) image processing algorithms for UHROCT. In the past 5 years Dr. Bizheva has built a laboratory with a number of state-of-the-art UHROCT systems, established collaborations with research groups at UW and other Canadian universities and clinics, as well as many companies, manufacturing OCT systems or related equipment.
