1996-1999: Senior fellow, Department of Laboratory Medicine, Prof. Lawrence Corey, University of Washington, Seattle.

Guided and supported a research project about the cellular immune response in herpetic skin lesions. Optimized a PCR-based method to determine the junctional size patterns of T cell receptors to analyze skin lesion biopsies for the presence of clonal expansions. Extended the use of this particular technique to study the immunology and virology of Chronic Fatigue Syndrome in monozygotic twins. Assisted in the development of a new liquid hybridization technique to assess the persistence and localization of herpes-specific T cell clones. Discover a new immune evasion mechanism use by Herpes simplex to avoid CD4 mediated T cells response.

Doctoral training

1994-1995:

Senior fellow, Laboratory of Animal Physiology, Prof. Jacques Urbain, Université Libre de Bruxelles, Belgium.

Initiated and developed a research project about the functional characterization of several human antigen presenting cell populations including monocytes and dendritic cells. First reported that GM-CSF is a potent inducer of B7 co-stimulatory molecule expression on monocytes. Discovered of a new regulatory mechanism of the B7 molecule on monocytes. Optimised bio-assay for the detection and titration of IL-2 and TNF- .
