I try to obtain an understanding of the mechanics of solid materials and translate this knowledge into predictive computational models, which can directly or in the long run be used by industry. Some of my current research interests are multiscale modelling (particular the quasicontinuum method), stochastic parameter identification, the treatment of random parameter fields, model order reduction approaches, nonlinear material models with plasticity and damage, and beam descriptions with beam-to-beam contact.
Summary of my CV:
2014-Today Research Scientist, Faculty of Technology, Science and Communication, University of Luxembourg, LU.
2013-2014 Lecturer, School of Engineering, Cardiff University, UK.
2008-2012 PhD, Mechanics of Materials, Eindhoven University of Technology, NL.
2005-2008 MSc, Mechanics of Materials, Eindhoven University of Technology, NL.
2002-2005 BSc, Mechanical Engineering, Eindhoven, University of Technology, NL.
Recognition:
- Biezeno Award 2013 (best 2012 PhD thesis in Solid Mechanics in The Netherlands, awarded by KIVI NIRIA).
- In the top 10 of best engineering PhD theses according to Dutch Technology Foundation STW.
- Distinction ‘Cum laude’ for MSc and BSc degrees.
