I welcome motivated graduate students interested in physical geography, biogeochemistry and environmental science. Current and potential projects include: i) impacts of climate change on mercury cycling and methylmercury production in Arctic ecosystems; ii) quantifying ecosystem metabolism (primary production and respiration) in ice-covered Arctic lakes; iii) reconstructing long-term trends in atmospheric mercury concentrations using tree-rings and ice cores; and iv) climate change impacts on lake and watershed biogeochemistry (carbon and nutrient cycling) in northern regions. Interested students are encouraged to please contact me for the most up to date information on potential opportunities at the undergraduate, graduate and post-doc levels.
