Job Description

Position Summary

The Liu Lab at Washington University School of Medicine is recruiting motivated, productive, independent, and collegial postdocs interested in using bioinformatics to interrogate gut immunity. The immediate projects may involve spatial transcriptomic analysis of clinical samples from people with inflammatory bowel diseases, mechanistic understanding of epigenetic and transcriptional regulation of gut epithelial cell differentiation, or mechanistic understanding of how diet modulate both innate and adaptive immune cells. This postdoctoral researcher will combine wet-lab molecular biology methods, dry-lab bioinformatic analysis, and a translational approach using samples from mice and humans. The overall goal is to understand mechanisms of gut mucosal immunity homeostasis. The start date is negotiable.
