Dra. Claudia Czimzik
Associate Professor at the Department of Earth System Sciences at the University of California, Irvine
Claudia received her undergraduate and graduate education in Germany, and obtained a Diplom in Geoecology from the University of Bayreuth (1999) and a PhD from the Max-Planck-Institute for Biogeochemistry and Friedrich-Schiller-University (2003) in Jena. She joined UCI’s Department of Earth System Science (ESS) as a researcher in 2003, and the faculty in 2011
Studies the impacts of climate change, alterations in natural disturbance frequencies (i.e. fire) and changes in land use and management (i.e. urbanization) on the cycling of carbon and nitrogen in terrestrial ecosystems.
Appreciates and predicts how human activities will impact the functioning of terrestrial ecosystems in the future and how changing terrestrial ecosystems will feedback to the climate system.
Focuses on high-latitude ecosystems (arctic tundra and boreal forests).
Expert in how climate and land-use change affect the storage of carbon in land ecosystems and the exchange of carbon dioxide, methane and carbonaceous aerosols between the land and the atmosphere.
Key interests: Climate change, Soil, Boreal and Arctic Ecosystems, Mega-Cities.

Researcher, French National Institute for Agronomic Research (INRA). Dijon, France
The research theme of my group is to understand the ecology of soil microbial communities, especially those involved in nitrogen cycling. We mostly focus on denitrification, which is a microbial respiratory process consisting in the reduction of soluble nitrogen forms, nitrate and nitrite, into gas, nitric oxide, nitrous oxide and dinitrogen when oxygen is limited. Denitrification is the main biological process responsible for the return of fixed nitrogen to the atmosphere, thus completing the N-cycle. It is also responsible together with nitrification for the loss of nitrogen, an essential plant nutrient and for the emission of N2O, an important greenhouse gas.
We are currently using N-cycling as model traits for bridging microbial community ecology, microbial processes and ecosystem functioning. For this purpose, both temporal and spatial patterns of microbial community activity, diversity and abundance are investigated.
