Rachel Gregor

Rachel is a PhD student in the Department of Chemistry at Ben Gurion University of the Negev, in the field of Chemical Biology.  She studies the communication between bacteria: how individual bacterial cells can sense one another and act as a larger unit by synchronizing their actions, for example to produce toxins; and how the human immune system can interpret this signaling in order to fight infections. She also investigates the small molecules that govern the coexistence and competition between different species of bacteria in a complex, natural microbial community, specifically the bovine digestive system. With antibiotic resistance on the rise, Rachel hopes to contribute to a better understanding of how infections are established and what molecules are involved, which can lead to the development of alternative routes to target or prevent infection.
