The Fetrow Group research focuses on understanding how proteins work in the cell by studying the intricate relationships that exist between protein function and structure, involving communication networks both within the protein and between proteins. To achieve this the group is developing methods and tools to aid in the early stages of drug discovery using Bioinformatics, Computational Biophysics and Systems Biology approaches. Some of the research underway includes the characterization and classification of enzyme functional sites, which provides information on the functional relationships between proteins, and can thus aid in the design of specific enzyme inhibitors. The methods we are developing can be used to quickly classify structures or sequences based on mechanistic determinants, contributing to the efforts to more accurately characterize unannotated or misannotated proteins. Other major research projects focus on using computational algebra or Bayesian techniques to model biological networks from time course data, such as gene expression or protein phosphorylation data. These techniques provide a fast way to discover dependencies in interaction networks involving modification of the proteins involved, which aids in the discovery of potential drug targets. In addition to these projects we also participate in research focused on the identification of biomarkers for specific diseases and exploratory research aimed at gaining a better understanding of certain biological systems.

All of our research requires a seamless integration of computational and biological techniques; thus, interdisciplinary collaboration is a very important part of the research done by our group. On-going collaborations include the departments of Computer Science, Biology, Mathematics, Biochemistry, Physics, Microbiology and Immunology, Internal Medicine (Molecular Medicine), and others. We also value collaboration with other universities and research facilities and currently have relations with Wake Forest University Baptist Medical Center, Virginia Tech, University of Minnesota, SUNY Buffalo, University of North Carolina in Chapel Hill, and University of California in San Francisco.
