Get To Know the Solids Staff

Barbara Fretter

Our solid dosage luminary and creative troubleshooter: After her graduation as pharmacist and dissertation in pharmaceutical technology, Barbara Fretter joined the University of Bonn as postdoc in 2007. Her research included instrumentation for tableting presses and powder deformation behavior. During that time, she was also in charge of industrial third-party funded projects. In 2014, she founded the company Solids Development together with Rob Lammens. Since then, she has helped many customers to get their formulations off the ground. Since 2018, Barbara has shared the company‘s ownership with Maarten Lammens.

Maarten Lammens

Our communicative strategist and multi-talent: Maarten Lammens strengthens our team since 2016. He entered the field of pharmaceutical technology coming from a different background. His studies of business informatics and his experience from having worked for a major consulting firm give him profound and broad knowledge with a focus on project and IT management. In addition, he completed an extraordinary and extensive training in pharmaceutical technology and came to be one of our company‘s PT specialists. Since 2018, Maarten has managed the company together with Barbara Fretter as managing director.

Rob Lammens

Our most experienced problem solver and grand master in lab and kitchen: Rob (Robert Frank) Lammens, PhD, brings more than 40 years of experience on solid dosage forms to the table. After his dissertation at the University of Leiden (Netherlands), he moved to Germany to work for the Bayer AG. He worked for the company for more than 23 years and grew to an extraordinary authority for measurement, instrumentation and process technology within the specialty of solid dosage forms. From 2001 to 2004, Rob taught as lecturer at the University of Bonn, in addition to his freelance consultancy work. In 2014, he launched the start-up „Solids Development“ with Barbara Fretter. At the end of 2018, Rob passed his business shares to Barbara Fretter and Maarten Lammens. Nevertheless, he continues to support us at Solids Development with all his competence and to dedicate himself to ambitious projects such as the realization of the OEB 5 lab.

In addition, Benjamin oversees prototyping and trial-oriented software tools.
