The overarching goal of my research is to characterize the host:pathogen interaction with special emphasis on the immune response to vaccination or pathogen infection. The Center for Genome Sciences (CGS) utilized genomics tool to perform genotyping (MHC and SNPs analysis); epitope mapping of the humoral response, and B and T cell repertoire analysis by VDJ rearrangement using high-throughput sequencing. These tolls are designed to complement and improve the information obtained from conventional immunological assays, and are collectively called: Immunomics. These agnostic tools are used in animal models (mice and non-human primates), in human samples (either from vaccination trials or survivors from outbreaks) and also in the reservoir of the pathogen of interest (Egyptian rousette bats, the reservoir for Marburg and Rav viruses).

With the better understanding of the host response to the pathogen we aim to define immunological biomarkers for protection and disease prognosis, develop diagnosis tools, and improve vaccine design.

The Immunomic group, within the CGS, is a join collaboration between National Strategic Research Institute (NSRI), the University of Nebraska Medical Center (UNMC) and the U.S. Army Medical Research Institute of Infectious Diseases (USAMRIID), lead Department of Defense (DoD) laboratory for biodefense research. The NSRI, UNMC and USAMRIID have partner to study dangerous pathogens, understand the key features of the immune response, and use those knowledge to develop therapeutics and vaccines.
