2011 Ph.D. Environmental Science, ETH Zurich, Switzerland: 'Quantifying Methane Emissions from Reservoirs: From Basin-scale to Discrete Analyses with a Focus on Ebullition Dynamics'
2006 M.Sc. Marine Science, University of California Santa Barbara, CA, USA
2003 B.Sc. Marine Science, Valedictorian, Stockton University, NJ, USA
I am a limnologist and an aquatic biogeochemist interested in the spatiotemporal variability of greenhouse gases in natural and man-made water bodies (lakes, reservoirs, rivers), how aquatic greenhouse gas contributions impact global carbon budgets, and they will be modified by global environmental changes, such as climate change.
