Job Description

Principal Investigator, Robert Barrett, PhD is looking for a Postdoctoral Scientist to join the team!

We are seeking a Postdoc with an interest in gastrointestinal disorders/inflammatory bowel disease (IBD) to join a funded study to elucidate novel mechanisms underpinning human intestinal fibrosis.

This study will adopt a personalized approach whereby iPSC-derived human intestinal organoids from Crohn’s disease patients will be used to determine how various components such as cytokines and cell-cell interactions each play a role in this process. This study is facilitated through our affiliation with the Inflammatory Bowel and Immunobiology Research Institute (IBIRI) which allows for the collection of biospecimens from a well-characterized IBD cohort and our organ-on-chip technology.
