Title: Biophotonics in health care: light-based technology to detect early cancer and image skin structures
Date: Thursday, January 14, 2016
Abstract: Biophotonics relies on light to understand the biology of living organisms at the cellular and molecular levels. Exploration of biophotonics could potentially result in clinically relevant diagnostic and therapeutic techniques that complement existing clinical modalities. In this presentation, I will go through the fundamental processes in light-tissue interaction and address the technological gaps in clinical diagnosis that biophotonics techniques are expected to fill. At BC Cancer Agency Research centre, our efforts focus on developing advanced non-invasive and real-time diagnostic techniques for detecting major types of cancers (skin, lung, and colorectal). I will go through some recent work on endoscopic and surface-enhanced Raman spectroscopy for early cancer detection. Being a part of the photomedicine institute at UBC, our group also developed confocal laser scanning microscopy and multiphoton imaging techniques for skin tissue imaging. Our recent progress on in vivo imaging of human skin using multimodal microscopy will be discussed.
Biosketch: Dr. Wenbo Wang obtained his doctorate degree from the imaging and spectroscopy lab (Paliwal’s group) at the University of Manitoba. As a graduate student, he worked with Dr. Paliwal to develop a hybrid spectroscopic technique that probed complementary molecular information about biological materials. After completing his graduate work, he moved to Vancouver to undertake postdoctoral training at the British Columbia Cancer Agency in the Integrative Oncology-Imaging Unit. Currently, he is a member of the Photomedicine Institute within the Department of Dermatology and Skin Sciences at UBC (in the laboratories of Drs. Zeng and Lui). His current research work focuses on development and application of optical spectroscopy and laser scanning microscopy techniques for cancer and dermatological research.
