Professor of Medicine of Medicine and Genetics
- Phone: 314-286-2005
- Fax: 314-286-1810
- Email: mmitreva@wustl.edu
There are two main threads to Dr. Mitreva’s current research. The continued development of molecular information, bioinformatics tools, and reagents for the study of parasitic infections is crucial, therefore she takes advantage of next-generation technologies and implements comparative genomics approaches to study the biology and cellular pathways of these important parasites. The second area of her research is focused on the human microbiome. The approaches she undertakes in these two areas have the potential for significant impact due to the recent explosion in the amount of data requiring analysis.
