Education

  • PhD, 1993, University of Vienna
  • BS, 1989, Biology, University of Vienna

Research Summary

The overarching goal of my laboratory is to define the interplay of immunologic, virologic and host genetic factors that determine control of human viral infections, to guide vaccine development and immunotherapeutic interventions. To address this goal, we focus on HIV infection.
