The Martinez-Guryn Lab in the Biomedical Sciences Program at Midwestern University (Downers Grove) invites applicants for an NIH-funded Postdoctoral Fellowship, specializing in microbiology and in vitro 3D organoid modeling.

The anticipated start date of the appointment is August 1, 2024. The appointment is anticipated for up to four years maximum, renewable annually. The Postdoctoral Fellow will contribute to NIH-funded research investigating the impact of fecal vs small bowel microbiota transplants on metabolism and nutrient transport in 3D cultures of small intestinal and colonic organoids. The project is part of an ongoing collaboration between Midwestern University (Martinez-Guryn Lab) and the University of Chicago (Eugene Chang Lab).

Essential Duties and Responsibilities

  • Plan and develop a research project that supports the mission of the college.
  • Support faculty in delivering lectures and course development and delivery (20% teaching in years 1-3)
  • Support the department, college, and university through service such as serving on Biomedical Sciences Master’s thesis committees (10% service in years 1-3)
