Lab Research

Currently, there are over 2,600 Salmonella serovars. The overall goal of Rachel's research is to understand how and why nontyphoidal Salmonella serovars differ in their ability to cause disease in humans and animals. To do this, she took a multidisciplinary approach to characterize and understand these differences at a::

  1. Genetic level: how genetic differences inform what we know about the severity of the disease that they cause, or the hosts that they may infect
  2. Molecular level: how virulence factors such as the typhoid toxin produced by some nontyphoidal serovars interact with host cells, and what the implications of exposure to this toxin are
  3. Multicellular level: how Salmonella cause disease in vivo
