• Led development of a late-stage monoclonal antibody purification process. Tasks included establishing a development timeline, devising the development strategy for each unit operation, designing and executing experiments, coordinating analytics and analyzing data, and providing timely updates to the project team and the rest of the purification group.• Developed various polishing chromatography steps in bind/elute and flowthrough mode, including a cation exchange (CEX) step to clear a product-related impurity and an anion exchange (AEX) step. Activities included screening binding and elution conditions in a plate format, dynamic binding capacity (DBC) determination, and condition scouting for gradient and step elutions.• Developed and optimized a depth filter-based whole cell harvest for a high cell density GMP antibody process. Optimized the same harvest operation for use in a platform antibody purification process.• Led successful early-stage viral clearance study campaign, including coordination, preparation, execution, and follow-up. Unit operations studied were Protein A capture, low pH viral inactivation, mixed mode-anion exchange chromatography in flowthrough mode, and virus retentive filtration.• Performed analytics as needed, such as HPLC titer, SEC-HPLC, ELISA, and LabChip CE.• Generated documentation of all laboratory activities including electronic lab notebook (ELN) and reports.• Supported tech transfer activities as a subject matter expert (SME) including batch production record review and person-in-plant (PIP) when required.• Performed high-throughput purification of samples for analysis using the Hamilton liquid handler.• Supported lab efficiency by 5S organization and freezer inventory development. Served as lab safety rep.

• Designed and executed experiments to improve and further understand a platform downstream process developed to purify lentiviral vector (LVV) produced in a suspension cell culture-based transient transfection process. Unit operations studied include harvest by depth and membrane filtration, other membrane filtration steps, capture chromatography, ultrafiltration and diafiltration (UF/DF), and formulation.• Supported the start-up of in-house pilot-scale capabilities. Performed scale-up experiments and purified LVV at the pilot scale to support scientific investigations of the full-scale process.• Performed subject-matter expert (SME) duties for technology transfers to external manufacturing partners by generating and reviewing batch records and reports, training operators, acting as person-in-plant (PIP) during establishment and scale-up runs, and coordinating analytical testing of process retains.• Managed a co-op student. Trained the student on the unit operations and associated data analysis, designed experiments, advised the student’s projects, and guided the student’s professional development.
