- Manage the Protein Sciences team by providing leadership, effectively prioritizing and organizing workload, and providing mentorship to team members, which include RAs and Associate Scientists.
- Manage molecular biology activities including designing and optimizing protein expression constructs and engineering novel reagent formats
- Protein expression of recombinant proteins and antibodies in multiple expression systems (mammalian, insect, E.coli)
- Protein purification using a variety of methods including affinity, ion exchange, size-exclusion chromatography.
- Biophysical characterization of proteins using CE-SDS, HPLC, DLS, and SPR-based methods.
- Trouble-shoot and optimize protein expression and purification strategies, perform complex experiments with strong attention to detail and documentation.
- Work with project teams to coordinate protein needs of early and mid-stage projects; serving as technical expert for protein engineering and protein sciences in order to support multiple drug candidate projects
- Maintain a workflow for protein production and an inventory of reagents.
- Manage CRO activities (DNA synthesis, plasmid generation, DNA production, protein production and purification) and identify CROs for analytical methods as needed (LC-MS/peptide mapping etc).
- Develop and execute experimental plans in timelines to meet program and corporate research objectives
- Excellent written and oral communication with cross-disciplinary teams and with external parties.
- Record detailed experimental procedures in laboratory notebooks and controlled documents
