The DMSO reductase family consists of proteins that catalyze oxygen atom transfer reactions. These proteins are characterized by a mononuclear Mo center that is ligated by one or two molybdopterin cofactors (through the two thiolates). DMSO reductase itself is ligated by two molybdopterin cofactors and catalyzes the reduction of dimethyl sulfoxide to dimethyl sulfide. This reaction is important...

Rachel Carson Syndrom

For years some ecologists have been convinced that pesticides are contributing to a decline in amphibian species around the globe. From an apparent epidemic of deformed frogs in Minnesota to the near disappearance of yellow-legged frogs from California’s Sierra Nevada Mountains, pesticides have been considered prime suspects. This suspicion is no doubt rooted in the belief by the ecological com...

Rachel Esselstein Research Statement

My research interests involve Finite Model Theory and Descriptive Complexity, an area of research nestled in the intersection of Combinatorics, Logic and Computer Science. Inspired by Ehrenfeucht–Fräıssé games, I have been studying local properties of regular colored graphs– in particular, the computational complexity of realizing a given set of neighborhoods in a graph.
