The Ottens Lab focuses on the following research fields:
- Micro bio systems technology and micro fluidics
- Bioprocess equipment miniaturization,
- General phase behavior of biomaterials, including crystallization and precipitation,
- Protein separation, purification and characterization,
- Fast conceptual bio(pharma)process design (HTPD), and bioprocess integration,
- Process chromatography of biologicals and nutraceuticals,
- Continuous bioprocessing (e.g. Simulated Moving Bed technology),
- Transport phenomena and bioseparation science.
