1 WENDY H. YANG Current Position General Information Post-Doctoral Scholar Maiden name: Liu Department of Environmental Science, Policy, and Management, 130 Mulford Hall #3114 Office: 131A Hilgard Hall University of California, Berkeley, CA Phone: Fax: Education Ph.D. Environmental Science, Policy, and Management (2010) University of California, Berkeley Dissertation Title: Quantification of and Controls on Dinitrogen and Nitrous Oxide Fluxes from Terrestrial Ecosystems; Advisor, Professor Whendee Silver B.A. (magna cum laude) Environmental Science and Public Policy (2003) Harvard University Senior Thesis Title: The Effect of Selective Cutting on the Carbon Budget of a Northern Hardwood Forest; Advisor, Professor Steven Wofsy Research Interests My research is in terrestrial biogeochemistry and ecosystem ecology with a focus on determining process rates and drivers of chemical transformations in the environment. I am particularly interested in the controls on greenhouse gas emissions, the effects of nitrogen deposition on soil nitrogen retention and loss, the effects of plant community composition shifts on soil nitrogen and carbon dynamics, and the coupling of biogeochemical cycles beyond carbon and nitrogen. An important component of my research is the development of novel methodological approaches using tracer and natural abundance stable isotope techniques, in particular to quantify soil dinitrogen emissions and gross fluxes of greenhouse gases.
