Research Scientist, Cell & Molecular Biology

The Research Scientist position reports to the Director, Molecular Biology supporting Ligand’s OmniAb Technology platform and will work on a team that generates and characterizes new strains of OmniChickens.  Duties include responsibility for Ligand’s cell bank of primordial germ cells (PGCs) and, propagate and genetically modify the cells to incorporate novel transgenes with enhanced capabilities.  Plan and coordinate the production of germline chimeras by reintroduction of the PGCs back into embryos.  Participate in construct building and molecular characterization of genetically modified PGCs and the characterization and evaluation of new OmniAb chickens once they have been established.  Characterization of new chickens includes studying B cell development, antibody repertoires, immune responses and/ or antibody discovery.  

The OmniAb group at Ligand consists of dynamic and innovative scientists that employ a variety of novel platforms to support our partners in discovering the best antibodies possible for their therapeutic applications.  At the core of OmniAb is the ability to engineer animals to generate affinity matured human sequence antibodies for use in conventional and novel formats.  We leverage our proprietary animals with state-of-the-art technology in antigen design, immunization methods and high-throughput single B cell screening to facilitate discovery of best-in-class antibodies.   We are looking for accomplished team players who are enthusiastic to contribute to the technological frontier of antibody discovery, and passionate in their desire to collaborate with partners to develop next generation therapeutics.  See for more details about the exciting science being performed at Ligand.
