Dr. Oppert received B.S. and M.S. degrees in biology from the University of Texas at El Paso. She received a Ph.D. in the area of protein biochemistry from Kansas State University in 1991. Since that time, Dr. Oppert has worked at CGAHR in the area of insect gut biochemistry.
     Our research mission is to find better, safer ways to control insect pests found in and around food storage areas, including grain storage and processing facilities and warehouses. Often these pests are even smaller than field pests and provide challenges when trying to understand basic digestive processes and physiological responses. Therefore, we have adopted a number of proteomics and genomics techniques, including 2-D gel analysis, multiphase chromatography, protein identification by sequencing, peptide fingerprinting and mass spec, subgenome characterization, and gene expression. Specific research areas include the use of proteomics and genomics to understand insect responses to digestive proteinase inhibitors and microbial toxins. Comparisons of differential responses in insects have been particularly enlightening. This research will lead to improved control methods for stored product pests.
