Research Assistant Professor
Ph.D., Microbiology and Molecular Genetics, Oklahoma State University

Dr. Ripp’s research centers on the genetic development of lux-based bioluminescent bioreporter systems for the detection of target chem/bio agents. Using bacteria and/or bacteriophage as sensory elements, in combination with self-generated bioluminescence emission, permits rapid, sensitive, and reproducible detection and monitoring in a user-friendly assay format. With the concurrent development of bioluminescent bioreporter integrated circuits (BBICs) as a biomimetic interface for living bioreporter organisms, assays can additionally be applied in a lab-on-chip format for unattended, wireless sentinel monitoring..
