Trypanosomiasis/Tsetse Research

Tsetse Fly

The Aksoy lab studies multiple aspects of tsetse flies, the vectors of African trypanosomes. Trypanosomes are the causative agents of the devastating Sleeping Sickness disease in Sub-Saharan Africa. The lab’s work spans a range of projects including tsetse immunity, reproduction and symbiosis, tsetse-symbiont and trypanosome interactions, tsetse genomics and population genetics, and trypanosome developmental processes in tsetse. The ultimate goal of our work is to improve current control methods and/or develop novel strategies to reduce or eliminate the transmission of Sleeping Sickness in Sub-Saharan Africa.
