Dr. Blair D. Siegfried
Professor and Chair, Insecticide Toxicology and Resistance Management
Dr. Blair Siegfried’s research is directed at quantifying the ecological risks of pesticide use and advancing our understanding of insecticide resistance evolution. A recent focus has been on transgenic maize hybrids that express insecticidal toxins from Bacillus thuringiensis (Bt). His laboratory has worked to increase genomic resources of important insect pests that are targeted by transgenic Bt maize through transcriptome sequencing. The goal of this research is to develop the resources for identifying changes in gene expression associated with toxin exposure and with resistance evolution. His lab is also developing methods to achieve gene silencing by RNA interference (RNAi) in order to elucidate gene function, identify and validate novel target sites, and to examine the potential for RNAi to serve as a direct pest management tool. Dr. Siegfried also serves as Chairman for the Department.
