Education:

Ph.D., Environmental Sciences, Université du Québec à Montréal, Canada,1997
M.Sc., Environmental Sciences, Université du Québec à Montréal, Canada,1992
B.S., Marine Biology, McGill University, Canada, 1989

Specialty:

Environmental Chemistry/Geochemistry, Biogeochemistry, Environmental Education.

Research Interests:

My scholarship activities unfold in two complementary directions. On the one hand, I try to assess the impacts that environmental perturbations have on biogeochemical cycling at ecosystem interfaces (coastal margins, lakes and flooded terrestrial zones, wetlands, urban atmospheres). On the other, I seek to address issues of scientific literacy in both a general social context as well as a specific one in the development of environmental curricula.
