Abstract:  We are interested in the study of cellular metabolism and its role in shaping biological function. Central to our research is the idea that metabolism involves the concerted actions of many enzymes, reactants, and products that together form a complex reaction network. This presentation focuses on network models of metabolism as an analysis framework, with examples drawn from two ongoing projects. The first example describes a dynamic model of CHO cell metabolism in fed batch culture, which is used to identify potential cell and process modification targets for productivity improvement. The second example describes a graph model of a microbial community, which is used to identify bioactive bacterial metabolites present in the gastrointestinal (GI) tract.
