Integrated Nanostructured Systems

Influence of bacteria in geochemical environments; role of adhered and planktonic bacteria in remediation; aqueous chemistry controls of bacterial adhesion; fate and transport of toxic metals; colloidal stability in aqueous and non-aqueous solution.

My research investigates the role of bacteria in geochemical systems. Specifically, I am interested in aqueous conditions that affect bacterial adhesion to mineral surfaces and how these interactions lead to increased or decreased contaminant mobility. I use Atomic Force Microscopy to investigate how changing aqueous conditions affect the adhesion of bacteria and other colloids to mineral surfaces.
