Our interdisciplinary group conducts environmental health (EH) research in food safety and neighborhood food systems in an urban environment. We are interested in assessing the attribution of different environmental sources in the dissemination of pathogens through urban food chain causing human health risks and microbial food safety. The focus of our research program comprises extensive laboratory-based investigation to develop biosensors and other molecular methods for rapid detection, screening, and characterization of pathogenic microorganisms or toxins from food, environmental (water, air, soil), and clinical samples.
