OverviewAI-generated summary

Terry Howell's research focuses on microbial food safety and the development of biosensing technologies for pathogen detection. His work includes investigating methods for inactivating foodborne pathogens like Salmonella and Enterococcus faecium on dried herbs, such as basil, using thermal treatments and gaseous chlorine dioxide. He has also explored the efficacy of these methods against specific strains. Concurrently, Howell has contributed to the field of biosensing, with recent publications detailing portable, wireless, and dual-camera systems for the rapid detection of E. coli O157:H7 in poultry meat. These systems utilize electrochemical impedance and coherent-light diffraction, incorporating machine learning for enhanced detection and strain-level recognition. Earlier work by Howell involved studies on bacterial antigens and their variation in oral streptococci populations, as well as research on cariogenic bacteria in rats.
