I lead the Thermal Conversion and Storage research line within the TFE department, focusing on the model-based analysis, design, and optimization of heat conversion and storage technologies through a fundamental understanding of transport phenomena. Together with my team, we aim to decarbonize heating and cooling across various sectors. Our key focus areas include magnetocaloric heat pumps and refrigerators, as well as heat storage systems utilizing phase change materials (PCMs) and thermochemical materials (TCMs). Our approach combines rigorous multiscale modeling with experimental validation.

I actively contribute to international collaborations, including SHC Task 67/40 on Compact Thermal Energy Storage – Materials within Components within Systems, and IEA ES Task 44 on Zero-Carbon Heat & Power Supply. Additionally, I have served on the advisory board responsible for shaping the heat storage roadmap in the Netherlands. I also represent the Netherlands on the Eurotherm Committee, which fosters European cooperation in thermal sciences and heat transfer. I am part of the management team at the 4TU Center for energy  and serve on the committee reviewing the university's collaboration with the fossil fuel industry at University of Twente.
