I am interested in the regulation of cell fate in normal physiological conditions vis-à-vis under perturbation by potentially toxic chemicals. Hierarchical networks of gene and protein interactions underlie cell fate choices in both “healthy” and “diseased”/”toxic” states. At The Hamner’s Institute for Chemical Safety Sciences, we are using a combination of genome-wide data analysis and computational pathway modeling to unravel and reconstruct the signaling and transcriptional regulatory networks that enable cells to respond in a finely-tuned manner to changing environments. This “integrative network toxicology” approach will be a key component of improved risk assessment for toxicity testing in the 21st century. In collaboration with Drs. Patrick McMullen, Harvey Clewell and Melvin Andersen, I am developing a spatial, multi-cellular “virtual tissue” model of the human liver to study the effects of exposure to the common environmental contaminant TCDD. I am also working with Drs. Qiang Zhang, Melvin Andersen and Rory Conolly (US EPA) to develop deterministic and stochastic models of B cell differentiation and its disruption by TCDD, as part of a Superfund Research Project led by Norbert Kaminski (Michigan State University). Along with Drs. Zhang and Andersen, I have been closely involved in the development and teaching of the Computational Systems Biology and Dose Response Modeling Workshop offered as part of The Hamner’s education and training program.
