Ecological Modeling

I am interested in how dynamics at the level of individual organisms conspire to generate patterns in ecological populations, communities and ecosystems.  The dynamics of individual organisms are influenced by their genomes and the environments they inhabit, which means that patterns we observe result from a complex interplay between the expression of genetic information, and interactions between individuals and their abiotic environments.  I use both mathematical models and experimental approaches to study ecological dynamics from  the level of transcription regulation to global biogeochemistry.  

Current research is focused on developing and analyzing the statistical properties of spatially explicit plant population models, understanding how phytoplankton nutrient uptake is linked to ecosystem- level patterns of nitrogen to phosphorus stoichiometry, and determining the consequences global climate change for carbon cycling in aquatic and terrestrial ecosystems.
