Research by Kathryn and her group focus on understanding mechanisms used by foodborne pathogens, as well as spoilage organisms, to adapt to stress conditions encountered during their transmission between abiotic environments, foods, and human and other mammalian hosts. Her current work specifically focuses on stress response systems and regulatory networks in the foodborne pathogen Listeria monocytogenes. Kathryn and her group also perform research on the transmission and control of bacteria that cause food spoilage with a particular focus on dairy foods and sporeforming spoilage organisms. Kathryn is currently the Ronald P. Lynch Dean of the College of Agriculture and Life Sciences at Cornell University.
Research by Martin and his group focuses on the pathogenesis of foodborne diseases, pre- and post-harvest food safety and on improving our understanding of the evolution and ecology of foodborne bacterial pathogens and their transmission from farm animals and environments through foods to humans. Both basic and applied research in the laboratory is targeted towards developing the scientific knowledge necessary to improve the ability to prevent foodborne and zoonotic diseases. In addition, Martin’s group also collaborates with Kathryn Boor’s group on research on transmission and control of bacteria that cause food spoilage, particularly in dairy foods.
The overall goal of Rachel's research is to understand how foodborne pathogens differ in their ability to cause disease. Rachel uses two model organisms, Salmonella enterica and Bacillus cereus, to characterize the genetic and molecular mechanisms underlying toxin production by these bacteria.
Rachel studies sporeforming bacteria from the farm level to the finished product. Her project's goal is to give farmers clear and feasible management practices that they can use to reduce sporeforming bacteria in raw milk and hopefully increase the shelf life of dairy products.
Ahmed Gaballa is a microbiologist who uses Genetics and Biochemistry to understand bacterial response to stress. He is specially interested in how bacteria coordinate the regulation of complex overlapped regulons to survive under stress conditions including oxidative, thiol and metal stresses.
Veronica leads a group of graduate and undergraduate students with the collective goal of defining the regulatory response, mechanisms, and key components that enable foodborne pathogens to survive under adverse conditions, and thus have the power to develop improved control interventions.
Maureen provides support to staff and students by preparing media, ordering supplies, and assisting with projects as needed. She prepares invoices for the LMT and processes samples from the CU Dairy and FPDL.
Sean is working on a project to develop an approach to evaluate new rapid methods for detection of foodborne pathogens, specifically to evaluate the ability of different commercial rapid detection methods to detect Salmonella from dry pet food and dark chocolate.
