About the role
About the Position
We are seeking a highly motivated and skilled Postdoctoral Fellow/Consultant to support the Principal Investigator, Co-Investigators, and research staff in the development and evaluation of next-generation prophylactics. The successful candidate will conduct proof-of-concept studies involving the design, expression, purification, and characterization of antibodies, single-chain variable fragments (scFvs), and bispecific scFvs (BS-scFvs) targeting key vaccine candidates.
About the Project
This position offers an exceptional opportunity to work at the intersection of computational protein design, structural biology, artificial intelligence, and translational vaccinology within a highly collaborative research environment. The candidate will bridge computational approaches with hands-on wet-laboratory research and contribute to the advancement of novel prophylactic strategies.
In addition to laboratory and research responsibilities, the Postdoctoral Fellow/Consultant will assist with overall project execution, including ensuring enrollment targets are met when applicable, maintaining protocol adherence, supporting monitoring visits, overseeing regulatory and administrative requirements, assisting with data management, and providing project close-out support. The successful candidate will work closely with investigators and research staff to ensure scientific, operational, and regulatory objectives are achieved.
