Presidentti auditorium, BioCity
Spring 2022 poster

Six students and early-career postdocs are welcome to have a lunch in restaurant Mauno and discuss with Prof. van Ommen after the seminar. This is a great possibility to learn hosting skills in friendly environment and create connections for future. Every student are welcome to join, in spite of which research group they belong to. BioCity Turku will offer the lunch.

Ruud van Ommen (PhD 2001, currently full professor) is a chemical engineer by training. He has a broad expertise in multiphase reactors and particle technology. In the past decade, he expanded his research to the scalable production of advanced, nanostructured materials. In 2011, he started an ambitious program (funded by an ERC Starting Grant) to investigate the interplay between agglomeration and coating of nanoparticles in the gas phase. This fundamental work is has led to practical applications, e.g. for energy conversion and storage, and for pharmaceuticals production. The second part of his research efforts are embedded in TU Delft’s e-Refinery institute. The efforts of van Ommen’s are mostly aimed at developing scalable reactor configurations for e.g. CO2 reduction, an production of the required materials.

Ruud van Ommen is a full professor in the Chemical Engineering department, and section leader of the Product & Process Engineering section in that department.  Moreover, he is director of the TU Delft Process Technology Institute (DPTI). He obtained both his MSc degree in Chemical Engineering at Delft University of Technology in 1996, and in 2001 a PhD degree at the same university. He has been visiting professor at Chalmers University (Gothenburg, Sweden) and the University of Colorado (Boulder, USA). He is co-founder of Delft IMP, a spin-off company from his group.
