Biosphere 2 at the University of Arizona and the Lawrence Berkeley National Laboratory in Berkeley, CA are in search of a creative post-doctoral scientist with experience in mechanistic modeling of ecosystem processes (encompassing hydrology, geochemistry, water and carbon cycling, and vegetation dynamics). The candidate will use an established model (ecosys) to analyze microbial and vegetation dynamics in the experimental hillslopes of the Landscape Evolution Observatory (LEO) at Biosphere 2. The science goals of this project are to simulate how plants colonize bare hillslopes, with interacting feedbacks among microbial communities, hydrology, and geochemical weathering, and to discover how these processes scale to the ecosystem.
