As an experimental physicist I like to use my perseverance to master complex measurement systems. I strive to obtain and represent observations to verify existing models or result in improved & corrected models. Having well developed instruments skills and patience to deploy high precision instruments at (and beyond) the limits of their abilities, I also like to utilise my experience to develop routines and algorithms that expand the usage of these systems. I like to discover what the models of systems are, and how key parameters can be defined in a meaningful, valuable way accordingly. In recent years, I mastered Python and its Scipy: I experienced its power as an exciting culmination of good coding practices that I mastered when creating data processing & visualisation chains in several languages, earlier in my career.
2011-2017 Product Development Engineer
Sonion Nederland B.V. Hoofddorp (NL)
Development, deployment and trouble shooting in measurement systems of varying complexity: Laser Vibrometer scanner, acoustic setups, microphones, force sensors, displacment sensor
Advise and support with acquisition and deployment of new measurement modalities. Design & implementation of data-processing algorithms. Subsequent support & maintenance.
Identification of key parameters and development of methods for standard characterisation & benchmarking.
2007-2009 Developer Flat Digital X-ray imaging detectors
Philips Medical Systems, Best(NL)
Evaluation and monitoring the image quality of flat X-ray imaging detectors for medical imaging systems. Specification and realization of test environments to simulate utilisation of prototypes in the product environment. Hence I realized the possibility to asses the impact of innovations and asses the impact of foreseen and unforeseen risks.
I intensely liked the opportunity to draw on my inventivity and ability to get interconnection details right and the gradual growing comprehension of an increasing number of system details. One of my major assets was my ability to organise and keep the unique experimental data together: this provided additional possibilities to simulate other non-project related issues and also simulate solutions in a more cost effective way. This all helped me to `exceed specifically strong in solving very tough problems'.
2006-2007 System Developer
LogicaCMG, Arnhem(NL)
Industrial Automation; Programming of firmware for embedded (arm) payment systems, configuration of embedded Linux multimedia PC-systems
Various software courses
in software testing, elementals of and best practices
Most of the coding preferences I already adopted during my experimental work, proved to coincide closely to the practices revealed to me during this time. Besides that I also learnt that my attitude is too generalist: I like working on software solutions to capture reality in this kind of `modelling framework' but I also feel a strong desire to be able to use hardware solutions which can be simple and more effective in some situations.
2001-2005 Research Fellow Experimental Physics
High Field Magnet Laboratory (HFML), Radboud University Nijmegen(NL)
Researching electronic properties of nanoscopic semiconductor and metal structures in high magnetic fields (up to 33 Tesla). This required picking up a great deal of meticulous experimenting skills with sensitive mechanical and cryogenic instruments and interference sensitive electronic measurement devices (e.g.Lock in amplifiers, nanovolt meters, etc.)
Development of a theoretical, electronic transport model to match the measurement outcomes to microscopic phenomena which govern the macroscopic transport properties in order to gain insight in the material quality achieved by the used deposition processes.
