How does pollution affect the local wildlife? Can the efficacy of a drug be predicted? These questions seem ostensibly unrelated, yet both can be addressed by our team using dynamical modeling methods, tools, and models. These models are often tailor-made to address a specific question or problem, such as predicting the disposition of chemicals through an animal or the speed of a phosphorylation cascade, but can often be generalized to handle any number of different situations. As just one example, we developed a predictive model of the hypothalamus-pituitary-gonad (HPG) axis in teleost fish in partnership with the USEPA, which controls the production of reproductive hormones through complex feedback mechanisms involving phosphorylation cascades, transcriptional activation, and enzyme inhibition. This model is able accurately predict a decline in individual fecundity in response to an aromatase inhibitor pervading a freshwater ecosystem. We extended this model by including the Leslie matrix method to provide a multi-scale approach that mechanistically links molecular interactions (i.e., molecular initiating events) with population carrying capacity over long time scales, such as years and even decades. In general, our team has the broad capability to develop predictive biological models of nearly any experimental setup, from flow-through exposure tank systems and microfluidic devices to enzyme and cellular assay data, and even to larval and embryo based in vitro assays. We will model your data by leveraging any and all available data in the literature, using it to train and validate our predictive models.What can our team do for you? We can develop predictive models that test mechanism hypotheses in your research, implement known drug interactions in vivo, or even reduce your experimental costs by developing models that take limited experimental data or even eliminate it entirely by leveraging in silico “data” (e.g., QSARs). Our diverse team of computational biologists, physicists, and theoretical chemists offers mechanistic modeling capabilities in the following areas:
