Expert guidance for biologics manufacture and compliance

Specialized consulting services to biotech and pharmaceutical companies, ensuring excellence in biologics manufacturing

Helping organizations improve and standardize processes, address gaps in control strategies and alignment with current quality and regulatory guidelines

About Jurgen

I am an expert in development and manufacturing of protein therapeutics using cell substrates of human and animal origin, with years of  experience working in biotech and pharmaceutical companies. Specialities are cell line development (i.e., CHO) and the compliance of processes with current regulatory guidelines for manufacture of highest quality safe biological products.

At BMS, I established appropriate controls to prevent viral contamination of manufacturing processes and facilities and ensured that internal procedures were aligned with current regulatory and quality guidance, e.g., ICH Q5A (R2), the main guideline for viral safety of cell substrates of human or animal origin. I implemented methods for genetic characterization of manufacturing cell banks and oversaw their tech transfer to a QC laboratory. In addition, I led the Process Analytics group, responsible for in-process testing of drug substance and support of PPQ campaigns.

At Novartis Vaccines, I established a “state of the art” CHO cell line development platform to generate manufacturing cell lines for viral subunit vaccines. I was responsible for all aspects of cell line development and characterization.

Prior to Novartis, at Dyax Corp., I developed technology for mammalian expression of fully human antibodies and led client-funded projects on antibody discovery and maturation.

I spent time as a postdoctoral Scientist in academia and at Immunex, and hold a PhD in  Biology from RWTH Aachen in Germany.
