johnson patriciaDr. Johnson's laboratory studies the biology and pathogenesis of the human-infective parasite Trichomonas vaginalis. This eukaryotic microbe is responsible for the most prevalent, non-viral, sexually-transmitted infection worldwide and is the most common parasite found in the US population. Molecular data reveal T.vaginalis as a remarkably divergent eukaryote, making it an excellent system for exploring biological diversity. Dr. Johnson's research focuses on four aspects of trichomonad biology: organelle biogenesis & evolution, regulation of gene expression, host:parasite interactions and genomics.
