Description du poste

## Staff ScientistApply: Onsite: Chicago, IL: Full time: Posted Today: JR35548**Department**BSD RAO - Research Staff**About the Department**The Jie Zhou lab is part of Department of Radiation Oncology at the University of Chicago. In close collaboration with the UC Comprehensive Cancer Center, the lab works at the interface of chemistry and biology to uncover how protein post-translational modifications (PTMs) and their associated enzymes regulate disease-relevant cell signaling and immune function. By understanding these mechanisms, we aim to identify new opportunities for targeted therapeutic intervention. Bringing together chemical biologists and protein, antibody, and cell engineers, we use advanced approaches in chemical biology, biochemistry, protein engineering, and synthetic biology to design innovative molecules, reveal complex biological mechanisms, and help drive the next generation of therapeutic breakthroughs. We employ a broad and integrated technology base, including synthetic chemistry, proteomics, functional genomics, and protein, antibody, and cell engineering. We also leverage combinatorial selection platforms such as phage, yeast, cell, and viral display, coupled with next-generation sequencing and bioinformatics. By integrating diverse expertise and technologies, we aim to advance understanding of human disease and inform the design of future immunotherapies.**Job Summary**We are seeking a highly motivated scientist to lead the discovery and engineering of functional antibodies for therapeutic applications. The successful candidate will build on an established viral display platform for the selection of functional antibodies and extend it across a broad range of therapeutic antibody formats and disease targets.
