Evolutionary Biology, BUEE PI
Our lab integrates studies at a wide range of both temporal and spatial scales in an attempt to identify general factors responsible for the generation of natural biodiversity in aquatic systems. We study a number of different freshwater and marine model systems using a combination of field, laboratory and experimental approaches to investigate how selective pressures contribute to the evolution of reproductive isolation. Studies on natural populations are complemented by experimental work in a large marine husbandry facility in which we can explore how environmental variation both promotes and constrains adaptive evolution.
Environmental Science, BUEE co-PI
Our lab studies drivers and impacts of water quality in freshwater and marine systems that are highly impacted by urbanization. Our study sites range from shallow urban lakes in New York City parks to the ecologically significant Jamaica Bay estuary. To understand the interactions between biological, physical and chemical processes we employ a variety of methods ranging from field observations to laboratory studies to modeling. Topics of interest include factors reinforcing dominance of different primary producers in phosphorus rich shallow lakes; impacts of nitrogen loading and physical characteristics on water quality and ecosystem structure in Jamaica Bay; and sources and fate of microplastics in marine waters.
Our lab focuses on understanding the mechanisms that drive patterns in diversity (including impacts of human activities), how diversity impacts ecosystem functioning and ecosystem services, and how ecology can inform, motivate, and learn from management actions. Most of the lab’s field projects focus on understanding, restoring, and conserving coastal marine communities (e.g., oyster reefs, salt marshes, seagrass meadows), while lab and computational work explore topics including oil spill effects, diversity in hyperdiverse systems such as kelp forests and rain forests, and the practice of species reintroductions.

Urban Microbial Ecology
Our lab uses DNA sequence data, in combination with culture-based bacterial analyses, to learn how microbial communities in urban environments are impacted by human activity. While only a small fraction of bacteria in most microbial communities can be cultured under laboratory conditions, total community DNA collected from environmental samples can be used as an indicator of the presence and relative abundance of most microorganisms, as well as the metabolic pathways and virulence factors represented within of the community.
Our lab studies ecological processes across physiological, community, and ecosystem levels in urban estuarine habitats. We are particularly interested in research questions related to the management and restoration of urban estuaries. We use controlled laboratory experiments, field studies, and modelling techniques to address our research questions.
