SHIFT: Day (United States of America)Seeking Breakthrough Makers About the Laboratory The Ruffner Laboratory is seeking an outstanding and highly motivated Postdoctoral Research Fellow to join an NIH R01-funded research program investigating fundamental mechanisms that drive eosinophilic esophagitis (EoE). Our research addresses a fundamental and largely unexplored question: how do inflammatory cytokine signals become durably encoded within the esophageal epithelium, and how does this contribute to persistent tissue dysfunction in EoE? The successful candidate will investigate how interactions between type 2 and type 1 cytokine signaling pathways shape epithelial cell responses, durable chromatin remodeling, and impaired epithelial barrier function in EoE. This work seeks to define mechanisms by which transient inflammatory signals are translated into persistent changes in epithelial state and function, with the potential to reveal new mechanisms underlying chronic mucosal inflammation. We are seeking an innovative, intellectually curious scientist who is excited by mechanistic biology and eager to develop scientific independence. The fellow will have substantial opportunity to develop hypotheses, design and lead experiments, pursue complementary research questions, publish findings, present at national and international meetings, and contribute to future grant development. Research will draw on complementary approaches in cell biology, immunology, molecular biology, and in vivo models, with opportunities to incorporate transcriptomic and epigenomic approaches. The Ruffner Laboratory provides a collaborative environment in which postdoctoral fellows are encouraged to take ownership of their projects while benefiting from interactions with a multidisciplinary team of investigators and trainees. The position is particularly well suited to a scientist seeking to build expertise at the intersection of immune signaling, epithelial biology, and chromatin regulation. Preferred Qualifications Experience in one or more of the following areas is highly desirable: *Flow cytometry, including sample preparation, acquisition, and analysis. *Animal models of inflammation, allergy, or epithelial disease. *Primary epithelial cell culture, organoid systems, or air-liquid interface tissue culture models. *Mucosal immunology, allergic inflammation, eosinophilic disease, or epithelial biology. *Cytokine/JAK-STAT signaling or inflammatory signaling pathways. *Chromatin remodeling, epigenetic regulation, transcriptional regulation, and/or genomic approaches, including familiarity with next-generation sequencing and data analysis
