In our lab we study phytoplankton ecology and biogeochemistry. We are specifically interested in how different phytoplankton groups respond to environmental perturbations such as changes in CO2, light intensity and nutrient availability. My students and I aim to not only characterize the responses of phytoplankton to a multitude of environmental factors, but also to understand the underlying processes of the measured responses, such as photosynthetic pathways, carbon acquisition processes and protein regulation.
