  • Partnering with External Manufacturing group and other key partners at Regenerons IOPS organization to provide technical assessment of CDMOs intended for GMP production and successfully transferring processes with immediate, first-time success.
  • Researching, identifying, and developing new technologies to improve processes, generate predictive process models, and pioneer novel at-line/in-line process analytical technologies (PAT) to ensure robust and controllable synthetic processes.
  • Authoring robust technology transfer documentation and supporting production with onsite presence during scale-up/GMP manufacturing activities.
  • Analyzing and presenting data in a clear and cohesive manner to a broad audience facilitating data-driven decision making.
  • Authoring, reviewing, or providing domain expertise for publications, reports, tech transfer documents, regulatory support documents and patents.
