Since my appointment as a faculty member in 2001, I have been leading my own research team. My original fields are particle technology and chemical reaction engineering. In recent years, I have shifted my research interest from more traditional chemical engineering topics to the scalable production of advanced, nanostructured materials. In 2011, I started an ambitious programme (funded by an ERC Starting Grant) to investigate the interplay between agglomeration and coating of nanoparticles in the gas phase. This fundamental work has been leading to multiple practical applications in health and energy applications, funded by several research grants and by industry. It has also led to a spin-out a company (Delft IMP) from my group.
