Bio

My broad research interests concern the immunobiology of infections by viruses and other intracellular parasites, mucosal immune regulation, and immune regulation of allergic responses. The ultimate aim is to develop improved vaccines against a variety of currently intractable diseases (eg. HIV/AIDS, TB, asthma) that have presented major difficulties for conventional approaches to vaccination.

A particular focus has been HIV immunobiology and vaccine development. We have recently developed a "prime-boost" vaccination strategy that generates sustained, high-level cell-mediated immune responses against encoded HIV antigens in both mice and macaque monkeys. Successful preclinical studies have led to the initiation of clinical trials of our vaccines beginning in 2003-04.

The outstanding potential of prime-boost vaccination has encouraged us to establish projects to develop effective vaccines against a variety of infectious and non-infectious diseases, including tuberculosis, Toxoplasmosis, asthma, and safer smallpox vaccines.

Finally, a key area of our work is a fundamental program of research into vaccine immunology, particularly immune mechanisms underlying the generation of highly effective T cell responses that we see following prime-boost vaccination. Our ultimate aim is to optimize vaccines against individual pathogens/diseases.
