Marine sediments throughout the world are populated with a diverse, abundant, and ecologically important community of small invertebrate animals and microorganisms. My research examines the ecological interactions between these small animals (referred to as “meiofauna”) and microbes (including microalgae, bacteria, fungi, and protozoans).

I have a particular interest in the importance of microorganisms as a source of nutrition for meiofauna and have developed several techniques for qualitatively and quantitatively assessing these relationships. Microorganisms also have complex commensal and/or parasitic relationships with meiofauna as they colonize their exterior surfaces. These “epibiotic” microbes are a continuing source of fascination for me.

Our laboratory has extensively examined the ecological impact of hydrocarbon and metal contaminants on microbial-meiofaunal food webs in coastal salt marshes, including ongoing research related to the 2010 Deepwater Horizon disaster in the Gulf of Mexico. We have also examined the potential ecological impacts of deep-sea CO2 sequestration.
