My research is centered around the interaction between the immune system and the pathogen, with a focus to developing vaccines and diagnostics. This includes:

  • Immunological studies of naturally acquired immunity
  • Identification of B and T cell antigens
  • Vaccine design using gene technology to assemble components from bacteria or viruses
  • Research into new vaccine adjuvants (adjuvants) and alternative forms of vaccination

Specifically, the main goal of my research is to develop a Chlamydia vaccine. SSI has been working on a vaccine for 15 years and has recently conducted a clinical phase I trial with promising results.
