Research Activities

Trypanosoma brucei  (T. brucei) is a protozoan parasite, which causes Human African Trypanosomiasis and nagana, a wasting disease in livestock.  T. brucei has a unique metabolism whose requirements are met by unique, dynamic organelles named glycosomes.  My research focuses on identifying pathways involved in the maintenance and proliferation of these organelles, which are essential and unique to the parasite.  Understanding these mechanisms will lead to the identification of new parasite-specific therapeutic targets.
