About Me

I am a full professor in Energy Technology within the Department of Thermal and Fluid Engineering. I finished my PhD in 1990 on the 'Mathematical Modelling of Coal Combustion in a Fluidised Bed'. From 1979-2009 I have been a scientist/consultant at TNO in Apeldoorn and in 2009 appointed by TNO as a Senior Research Fellow. In 2000 I was appointed as a professor in Thermal Conversion Processes at the University of Twente and since 2009 I became a full professor.

I am an expert in the field of thermal conversion processes (pyrolysis, gasification, combustion, torrefaction) and in energy systems (conversion, storage and system analysis). I have carried out a large number of commercial research and development projects for national and international clients. Furthermore I have invented and developed new advanced conversion technologies and demonstrated in practice.

From 2011 I have been the Scientific Director of the PDEng programme (Professional Doctorate in Engineering) on Energy and Process Technology. The PDeng programme is a two years post-Master designer programme at the University of Twente. Since 2015 I was also a Scientific Director of the new Engineering Institute of the University of Twente. From 2013-2017 I have been a member of the Management Team of the Engineering Faculty.
