Research Interest
Virulence in prokaryotes is a multifactorial trait and in many cases, or at least in the short term, is adaptive in the organism's niche. While understanding virulence determinants at the molecular level is a key in devising protective methods, predicting their origin,stability, and behavior is more important in deciding usefulness of these protective methods on the long term.

My interest involve applying  a combination of genomic, proteomic, and evolutionary approaches to understand this issue in prokaryotes of veterinary and medical importance.
