Research Interests

I am a biogeochemist interested in carbon and nitrogen cycling within coastal and marine habitats. Microbes are important drivers of ecosystem function, so my research takes an interdisciplinary approach by combining measurements of biogeochemical rates (via analytical chemistry) with characterization of the microbial community responsible for them (next-generation sequencing and bioinformatics). I am especially interested in how these ecosystems respond to nutrient loading and climate change, both regionally and globally. Current projects focus on examining carbon storage and nutrient removal in salt marshes and mangroves, both of which are highly valued “Blue Carbon” ecosystems. I am also developing an ocean acidification dosing system, allowing for future research questions to examine life in acidified waters.

I am always looking for undergraduates to assist and contribute to this research, and welcome new ideas, too!
