My research combines experimental and theoretical techniques to investigate mechanisms in virology, immunology, and infectious disease epidemiology. Mathematical studies used in conjunction with data can suggest unforeseen biological mechanisms, determine biologically important rate parameters and evaluate pathogenic mechanisms that are difficult to test directly. A systems biology approach that couples mathematics with experiments has the potential to advance our basic understanding of pathogenic mechanisms and to lead to new therapeutic strategies.
Currently my research group is examining the control of lentiviral infection, including human immunodeficiency virus (HIV) and equine infectious anemia virus (EIAV). We use mathematical and computational models of viral dynamics with clinical and experimental data to elucidate the determinants of virus control and escape. Our long-term goal is to uncover fundamental viral or immune mechanisms and to develop effective vaccine strategies.
