Personal profile

Research Interests

The research focuses on environmental and microbial transport processes, with particular emphasis on understanding the basic processes that control interfacial transport in aquatic systems and the coupling of physical transport processes with biological and biogeochemical processes. I seek to define critical structure-transport-transformation relationships in dynamic natural environments such as rivers and in surface-attached microbial communities (biofilms). My work is highly collaborative and encompasses basic fluid mechanics, particle transport and morphodynamics, aquatic and surface chemistry, and microbiology. Important applications include contaminant transport and water quality, microbial habitat conditions and benthic microbial ecology, nutrient and carbon cycling, ecosystem degradation and restoration, control of biofilm-based infections and biofilm-resident pathogens in building systems, and the transmission of waterborne disease.
