Oxidation of Metallic Mercury by Anaerobic Bacteria Abstract: Anaerobic microorganisms play a central role in the global mercury (Hg) biogeochemical cycle through their catalysis of Hg methylation. In this presentation, I will describe how anaerobic bacteria oxidize elemental mercury and produce neurotoxic methylmercury. The environmental relevance of my recent findings will be discussed in the context of mercury contamination in groundwater aquifers and estuary sediments.

Metal-Ligand Controlled Synthesis and Performance of Metal and Metal-Like Nanoparticles Abstract: Metal ligand chemistry impacts nearly every aspect of nanoparticle formation, physical properties, and utility. We develop methods to study and leverage these interactions to produce tailored metallic and metal-like nanoparticles with dimensions spanning the nanoscale (1-100 nm). Here, we discuss how metal-ligand interactions may be used to mediate the incorporation and distribution of metals in and on discrete, colloidal nanoparticle substrates, as well as their optoelectronic properties once formed.
