Research

Research in my lab focuses on characterizing how and why marine microorganisms vary over time and space. By integrating field and lab-based studies with multiple complementary approaches (e.g., microscopy, molecular, and geochemical techniques), we explore a diversity of research questions related to microbial community distributions and interactions. However, we are particularly interested in how mortality processes (e.g., top-down controls), not just variations in the growth environment (e.g., bottom-up controls) influence the structure and function of marine microbial communities. Given that marine microorganisms are major drivers of biogeochemical processes in the oceans, determining the distributions, rates and interactions of microbial predators (i.e., microzooplankton grazers and viruses) is critical for adequate representation of plankton dynamics in ecosystem models and for developing a predictive understanding of lower trophic level response to climate variability.
