I head the heterogeneous catalysis and sustainable chemistry group at the University of Amsterdam. We discover new catalysts and materials for making bulk chemicals and sustainable energy applications. Check out our short film on YouTube.

I also have two companies: Sorbisense in Denmark, that makes passive samplers for soil and groundwater, and Yellow Diesel in the Netherlands, that designs catalysts and processes for biodiesel manufacturing and biomass conversion.
