Current Research Activities

Biological Systems and Organisms

My interests have been focused towards the biochemical characterization of i) enzymes associated with parasite metabolism, ii) membrane transporters essential for parasite survival or involved in the development of resistance to drugs, and iii) proteins involved in cellular differentiation and parasite-host interaction. Additionally she has analyzed functional phenomena involved in host-parasite interactions and characterized natural products and target-oriented designed compounds as potential therapeutic agents. All these studies have been performed using Leishmania and Trypanosoma as a model.
