Jessica Hill is a current postdoctoral researcher in the Osborne Nishimura lab whose research focuses on investigating the genetic and immunologic dynamics between intestinal epithelial cells and gut bacteria within C. elegans, allowing her to address fundamental questions over host-microbe interactions.

Her research interests encompass understanding the development and progression of inflammation within the gastrointestinal tract, in addition to understanding how gastrointestinal inflammation affects aspects of host physiology. This area of research is of considerable relevance to public health as inflammation-related diseases are the leading cause of morbidity and mortality worldwide. To gain a more comprehensive understanding of immune function and inflammation throughout the health continuum, she has utilized several model systems including humans, pigs, guinea pigs, mice, rats, and now Caenorhabditis elegans.
