Postdoctoral Fellow, Quantitative Biosciences (in vitro pharmacology)

Location: Boston, MA

Summary: We are seeking a highly motivated Postdoctoral Fellow to join our Quantitative Biosciences team to develop physiologically relevant in vitro models to investigate the MoA of novel immunotherapies for inflammatory diseases. The role will focus on assay development using human intestinal organoids and primary immune cells. The Postdoctoral Fellow will design and implement the in vitro models to assess potency, mechanism of action, and combination effects of therapeutic candidates.

Key responsibilities

• Develop co-culture and functional assays to measure the crosstalk between intestinal epithelial cells and immune cells.
• Design experiments to profile biologics and small molecules across target panels and immune cell subsets.
• Understand the pharmacology and mechanism of action of therapeutic targets in human intestinal organoids and primary immune cells.
• Confirm findings in orthogonal assays with engineered cell lines and other molecular biology approaches and transcriptomics studies.
• Independently design, plan, execute, and interpret assay data.
• Maintain detailed experimental records.
• Present the research work at internal and external meetings and publish in high-impact journals.

Required qualifications

• Hold a Ph.D. or Ph.D. completed within 6 months of hire -in Immunology, Cell Biology, or a related discipline, with a proven track record of first-author publications.
