Brief synopsis of current research:
I am a biological oceanographer with expertise in phytoplankton ecophysiology. I have several years of experience doing research related to the physiological responses of phytoplankton to hydrodynamic processes. I have been involved in many national and international research programs such as JGOFS. I worked in polar and subpolar areas on phytoplankton ecology and, more recently, on the importance of the microbial loop in planktonic ecosystems. The main focus of my research is to study the environmental consequences of enhanced UV radiation in a series of mesocosm experiments in which captured sea water (and its associated chemical and biological constituents) are exposed to varying elevated levels of UV-B radiation. I have brought together at the Rimouski laboratory facilities a team of scientists that is actively studying UV effects on coastal ecosystems.
