This flagship series brings together Parliamentarians with experts in science and engineering, showcasing outstanding Canadian research accomplishments. Its purpose is to provide unbiased insight into topical scientific issues, within a non-partisan forum. This prestigious forum represents a unique opportunity for scientists to communicate important findings to a distinguished and influential audience.

The series is organized by PAGSE, an umbrella group of 25 + science and engineering organizations operating under the auspices of the Royal Society, and is supported by NSERC.

When light meets matter: implications for health and high technology

Tito Scaiano
University of Ottawa

Chemical reactions induced by light are the mainstay of life on earth and the key to new advances in technology and health, but they can also cause concern when they lead to problems such as skin cancer. Our ability to benefit from some light-initiated processes, and to prevent others, hinges on our understanding of how light interacts with matter and of the resulting molecular reactions. Tito Scaiano will discuss recent advances in photochemistry, including how it is being used to detect DNA damage, verify food authenticity (when food has been irradiated) and develop new materials that range from safer sunscreens to higher-capacity computer chips.

For the last three decades Professor Scaiano has been studying the kinetics and mechanisms of light-induced chemical reactions. Internationally renowned for his advances in this field, he holds the Canada Research Chair in Applied Photochemistry at the University of Ottawa. In 2002, he was awarded the Gerhard Herzberg Canada Gold Medal for Science and Engineering, Canada's most prestigious science prize.
