Key areas of expertise are in the proteomics and metabolomics, or the analysis, identification and quantification of proteins and metabolites. Liquid chromatography-mass spectrometry is the main tool that we use to analyze samples for detecting and measuring levels of proteins and small molecules. Current Projects Plant-based Research: Modeling biological networks in Arabidopsis; metabolite profiling of transgenic poplar and soybeans. Animal-based Research: Inter-cellular signaling in liver mimics; Development of a revised amino acid requirement system for bovine lactation; Lipid analysis of serum and animal tissues. Microbial Research: Analysis of the extracellular space of filamentous Cyanobacteria; Phenotypic predictions in Cyanobacteria, Proteomic analysis of Clostridium difficile and Bacillus subtilis.
