Research Interests

The goal of our research is to utilize modern biochemical, cellular and molecular techniques to investigate structure function relationships in proteins essential for cellular metabolism and chromosome function. We are especially interested in understanding processes involved in cellular division and chemical detoxification. One focus of our work involves the isolation and characterization of genes required for meiosis and the analysis of meiotic mutants of Arabidopsis to better understand proteins that control chromosome structure during meiosis. One family of genes currently under study is required for chromosome condensation and sister chromatid cohesion during meiosis and mitosis. A second set of genes under study is responsible for controlling meiotic gene expression. This project utilizes studies at the cellular, molecular and biochemical levels.

A second focus of our laboratory involves studies on the glyoxalase pathway, which is involved in cellular detoxification and the regulation of cellular proliferation. Molecular, biochemical and structural studies are underway to more accurately determine the exact role(s) of glyoxalase II-like proteins in the cell. Structure/function studies on glyoxalase II-like proteins are also underway to identify and characterize the active site of the enzymes and understand their kinetic mechanisms. Goals of this work include the rational design and synthesis of glyoxalase II inhibitors that could be used as anti-cancer and anti-malarial agents and determination of the biochemical role of ETHE1, which is responsible for Ethylmalonic Encephalopathy, a complex metabolic disorder in humans.
