Role summary:

Incumbent will provide direction, oversight and support for generation of antibodies as tool reagents for evaluating bacterial vaccines including antibody characterization and their use in development of preclinical assays. The incumbent will be responsible for the generation and development of different types of antibodies with the clear focus of monoclonal antibodies originated from B-cells with respective functional activity; primarily performing bench work. Duties will include screening, expression, purification and their characterization with various bioanalytical methodologies and functional assays. Supporting the generation of antibodies based on the hybridoma technology will be a part of the role. An important role is guidance of more junior people in the lab. The ability to work in teams, write reports, standard operation procedures (SOPs) and publications for peer review journals is required. The incumbent will be involved in project management, being closely aligned with bacterial vaccines, vaccines research and development management and multiple program teams.

Role responsibilities:
