Research Scientist - Algal physiology and nutrient dynamics

Canada Centre for Inland Waters (Burlington, ON)

CURRENT S&T / RESEARCH - Conducting research on nutrient dynamics, algal ecological response and ecosystem variability for the rehabitilation and conservation of water quality

• Nutrient dynamics: understanding their sources and sinks in aquatic ecosystems using stable isotopes and spectrofluorometry
• Algal ecology and physiology: understanding the response of the algal community to dynamic environmental conditions
• Ecosystem spatial and temporal variability: understanding the response of aquatic ecosystems to remediation activities

PROFESSIONAL ACTIVITIES / INTERESTS

Program Chair, Canadian Assocaiation for Water Quality Central Symposium of Water Quality Research

Peer-review of research grants and scientific journals

Scientific lead for Environment Canada Aquatic Ecosystem Management Research Lake Simcoe research initiative
