Research Scientist - Modelling of atmospheric transport and multicompartment fate of persistent organic pollutants (POPs) and heavy metals

4905 Dufferin Street (Toronto, ON)

CURRENT S&T / RESEARCH - Contributing to Environment Canada’s mandate for risk assessments and improving the understanding of environmental fate of toxic chemicals

• Modelling regional and global-scale atmospheric transport and deposition of POPs and heavy metals
• Impact of climate variability and climate change on the budget of persistent toxic chemicals in multi-compartments
• Impact of extensive use of organochlorine pesticides on climate change
• Environmental and physical process of POPs in the atmospheric boundary-layer
• Development of the state-of-art mathematic models for simulating the transport and budget of POPs

PROFESSIONAL ACTIVITIES / INTERESTS

Research grant and journal paper reviews, including reviewing the Government of Canada Program for International Polar Year (IPY) funding proposal

Supervisor of contract scientist and co-op student

Annually assessing and reporting the atmospheric transport and loadings of POPs to the Great Lakes for the Great Lakes Binational Toxic Strategy (GLBTS)
