Mary Ann McDowell Professor
The overriding research focus in the laboratory is the biology of infectious diseases. Infections account for 16.2% of annual deaths worldwide, being responsible for 2 of 3 deaths in children under age 5. Successful control strategies to combat these devastating diseases must be multi-factorial, combining attacks on human infections and targeting diverse aspects of pathogen biology. This combinatorial approach provides the conceptual framework of the McDowell research program to investigate immunology, host cell-biology, pathogen diversity and insect vector biology, using both laboratory models and field-based studies. Dr. McDowell’s group exploits Leishmania infection as a model to address fundamental immunological and cell biology questions. They study both murine and human systems utilizing a range of immunological, biochemical and genomics techniques, including drug discovery for new chemotherapeutics. In addition, the McDowell research program extends to address questions specific to the phlebotomine sand flies that transmit Leishmania and other insect vectors of human disease and to develop insecticides to control vector-borne diseases. One project evaluates the feasibility of using sand fly saliva as a vaccine component to combat leishmaniasis by assessing human immune responses to sand fly saliva and genetic variability of sand fly populations in the Middle East. Further, the McDowell laboratory coordinates an international effort to sequence the genome of two sand fly species. They also utilize insect-vector genome data for the identification and screening of novel insecticide targets and further characterize the role of these targets play in the biology of mosquitoes and sand flies.
Dr. McDowell previously was the Principal Investigator of the NIH/NIAID Bioinformatics Resource Center (BRC) VectorBase and currently is a Joint-Investigator of the Eukaryotic Pathogen, Vector and Host Informatics BRC (VEuPathDB), a web-accessible knowledgebase that provides access to diverse genomic and other large scale datasets related to eukaryotic pathogens and invertebrate vectors of disease.
