About

Marcel Ottens is a prominent researcher in the field of bioprocess engineering, with a particular focus on downstream processing, chromatographic separations, and high-throughput experimentation for biopharmaceutical manufacturing. His work has significantly advanced the development of efficient, scalable purification strategies for complex biological molecules including proteins, oligosaccharides, and therapeutic antibodies. Ottens is perhaps best known for his contributions to high-throughput methodologies that accelerate chromatographic process development. His 2010 study on isotherm determination and thermodynamic modeling of protein adsorption on mixed-mode adsorbents garnered 170 citations, establishing him as a leader in applying mechanistic models to chromatography. Complementary work on hydrophobic interaction chromatography and aqueous two-phase systems further demonstrates his breadth across separation science. A recurring theme in his research is miniaturization and automation — reducing material consumption and time in process development workflows, a critical challenge in biopharmaceutical manufacturing where sample availability is often limited. His more recent contributions on omics-guided purification and robotic screening platforms reflect a forward-looking integration of data-driven and experimental approaches. Collectively, Ottens' research has provided the biopharmaceutical community with practical, scientifically rigorous tools for designing robust, cost-effective purification processes.
