I am working to characterize novel behaviors in the model bacterium Escherichia coli in the topic of carbon and nitrogen nutrient signaling. The main finding I am investigating novel carbon catabolite repression (CCR) of glucose- and other sugars- by amino acids in peptide based media. We have been able to demonstrate that amino acids inhibit uptake of glucose while they are taken up first. Biomass generation over the course of two hours occurs while glucose concentration remains constant. This is unusual because glucose is nearly universally viewed as the most preferred source of carbon. Instead, the hierarchy is more complicated than originally thought, and some novel mechanism is preventing glucose uptake from occurring during early stages of growth. The behavior is not unique to glucose, and even occurs when the preferred nitrogen source, ammonium, is present in excess.

My work is determining and differentiating protein binding to DNA. I work on both the computational and experimental aspects of this problem. My projects include: Characterization of Alginate lyases of Vibrio splendidus 12B01 and 13B01; Characterization of Laminarinases of Vibrio breoganii IC10; Determination of McpC motif binding in Bacilus subtilis; and computational determination of expression profiles of various sigma factors in Escherichia coli.
