Responsibilities
Design experiments and perform hands-on buffer/media preparation and cell culture operations in shake flasks, ambr15, ambr250, bench-scale bioreactors, and novel cell culture platforms
Lead aspects of optimizing chemically defined cell culture media to improve productivity and modulate product quality for fed-batch and perfusion processes
Apply statistical and computational tools (e.g., DoE, multivariate analysis) to interpret experimental data and guide media formulation strategies
Elucidate mechanistic understanding of key factors and associated metabolic pathways relating to cell culture medium and process development using advanced bio-analytical techniques such as bioassays, proteomics, and metabolomics
Participate and work cross-functionally within and outside of biologics technical development to achieve common goals
Prepare technical reports, protocols, presentations, and manuscripts for internal and external dissemination
Occasional weekend work may be required to support cell culture operations
Maintain accurate and detailed laboratory records in compliance with institutional and regulatory standards
Adhere to department budget and all training, compliance and safety requirements. Support general laboratory upkeep
Qualification
