    Professor Aksoy is a tropical medicine researcher whose work focuses on the epidemiology of insect transmitted (vector borne) and zoonotic diseases.  Her research has been on tsetse flies and the pathogenic parasites they transmit that cause highly neglected and fatal diseases of humans in Africa, known as Sleeping Sickness. Her laboratory focuses on deciphering the vector-parasite molecular dialogue and parasite development during the transmission process with the ultimate goal of identifying novel targets of interference and developing transmission blocking vaccines to reduce disease.  Her fundamental and interdisciplinary work on tsetse and its microbial symbionts has identified key principles that shape host-microbe interactions. Her studies with tsetse's mutualistic microbes identified nutritional contributions that facilitate female fecundity and mediate host immune system development. Her studies with tsetse's commensal microbiota led to a novel biological method, coined as paratransgenesis, in which anti-parasitic molecules are synthesized in the beneficial gut microbes, thus making the gut environment inhospitable for disease causing parasites. Ability to spread such modified microbes into natural insect populations is being explored to reduce disease transmission as a novel biological method.Dr. Aksoy maintains collaborative research activities with Yale researchers as well as with multiple universities and research institutes in Africa. Their studies in Kenya and Uganda investigate the epidemiology of Sleeping Sickness disease, with a focus on understanding the major drivers that sustain disease transmission, as well as on population genetics of flies and parasites and their microbiota. She initiated and led a large international consortium that eventually sequenced the genome of six tsetse fly species. This effort vastly expanded molecular knowledge and genomic resources on this neglected disease vector, and collectively expanded research capacity in bioinformatics and functional biology in many laboratories in sub-Sahara Africa. As the co-editor in Chief of the journal PLoS Neglected Tropical Diseases between 2007-2020, she has been a major voice for building research and publication capacity for global neglected tropical diseases.  Throughout her professional career, Aksoy has been an advocate of and innovator in Global Health; served as a dedicated mentor to students and scientists in the US and in Africa, China, Italy and Turkey helping to prepare the next generation of leaders in the fields of epidemiology and zoonotic disease control.
