Associate Professor / Programme Director EngD Energy & Process Technology

Over mij

I am a Programme Director of the Engineering Doctorate (EngD) Energy & Process Technology and an associate professor in the Department of Thermal and Fluid Engineering. I am responsible for the research line on Energy Efficient Processes, focusing on multidisciplinary and inter-sectoral investigations toward the optimized use of renewable energy.  I received my Ph.D. in December 2010 at the University of Twente on the work “Vibro-acoustical instabilities induced by combustion dynamics in gas turbine combustors”.

Spray Drying
Physics & Astronomy


I am involved in the research on the intensification of thermal processes via development of energy efficient novel power systems, engines, reactors and processes. The main focus is placed on multicomponent and multiphase flows, liquid atomization, droplets evaporation and drying, combustion, supercritical fluids, heat transfer and fluid dynamics. Renewable processes and transition to the future technologies are of prime interest.
