Computer Science

ABOUT ME

I am a Ph.D. candidate at the faculty of Electrical Engineering, Mathematics and Computer Science of the University of Twente. I am affiliated with the group Design and Analysis of Communication Systems group. I was born in ’t Harde, 1989, and in 2013 I obtained my Master’s degree in Computer Science for the track Methods and Tools for Verification with the final topic Fluid Survival Tool: A model checker for hybrid Petri nets at the University of Twente in Enschede with the committee of Anne Remke (1st supervisor), Rom Langerak (2nd supervisor), Boudewijn Haverkort and Hamed Ghasemieh. In November 2013, I began my Ph.D. research on the topic of data centre energy-efficiency under the supervision of Boudewijn Haverkort.
