About

As an Upstream Pilot Scientist at Lonza, I bridge upstream and downstream operations with comprehensive expertise across the biopharmaceutical production workflow. My progression from downstream processing (DSP) of monoclonal antibodies to upstream pilot operations reflects my commitment to end-to-end process mastery.

I hold a Master's degree in Biopharmaceutical Development from the University of Leeds, where I specialized in protein aggregation research at the Astbury Centre for Structural & Molecular Biology.

I am deeply committed to workplace safety and environmental stewardship. As a voluntary EHS Focal Point, I hold certifications in First Aid with Oxygen Therapy, Tier II Bronze Command Spill Response, and 6S (Orange Belt), and I actively serve in these roles on a regular rota basis. This combination of technical expertise and safety leadership supports safe, compliant, and high-quality biopharmaceutical operations.
