Professor Yildirim is an applied mathematician whose research is on mathematical modeling of biological systems with a focus on regulatory biochemical networks. Although many intracellular regulatory networks have been extensively studied using advanced experimental techniques, it has turned out to be quite difficult to make predictions about how individual components are assembled and dynamically regulated, and how the behavior of metabolism as a whole are related with the properties of the individual parts. Dr Yildirim is interested in development of quantitative mathematical models that are comparable with experimental data to address such questions.
Before coming to New College, Professor Yildirim held postdoctoral positions at UNC-Chapel Hill and McGill University.
