I wrote several white papers to educate customers. I did physical characterization of X-ray anti-scatter grids and influence of grid properties on X-ray image quality en cooperated with other players in the field to develop international standards to characterize anti-scatter grids.I initiated and lead the development of laser sintering of tungsten products for medical and non-medical applications - DMLS, SLS, SLM. I introducted Additive Manufacturing within Philips for the production of Anti-Scatter Grids for CT systems. I setup a production facility, started market development (OEM) and innovation.I cooperated with suppliers to further improve the additive manufacturing process.I did many metallurgical researches on tungsten and other heavy metals.I developed an innovative packaging with low carbon footprint.I in-sourced a post-processing method of metal components to improve surface finishing and net-shape etching.

As an employee of Philips Research I helped in the development of high resolution scanning transmission electron microscopes (STEM), spherical aberration (Cs) correction and electron optics for FEI (now Thermo-Fisher) I wrote a patent on alignment of Cs-corrector which is granted. Atomic resolution was achieved. I automated the alignment of the TEM (autofocus, autostigmate, etc) in Python. This saves hours a tedious alignment work for the operators.I investigated the physcial… Show more As an employee of Philips Research I helped in the development of high resolution scanning transmission electron microscopes (STEM), spherical aberration (Cs) correction and electron optics for FEI (now Thermo-Fisher) I wrote a patent on alignment of Cs-corrector which is granted. Atomic resolution was achieved. I automated the alignment of the TEM (autofocus, autostigmate, etc) in Python. This saves hours a tedious alignment work for the operators.I investigated the physcial limits of Environmental SEM. I was trained in the operation of a (E-)SEM. I developed electron-optical improvements on high-power X-ray tubes for medical applications for Philips Hamburg. Show less

PhD position (OIO) at the Rijksuniversiteit Groningen in the polymer chemistry department on the topic of phase behavior of polydisperse copolymers. I conducted Monte Carlo simulations and calculations on polydisperse mixtures of copolymers to see which microstructure would be thermodynamically favourable under certain conditions, most importantly temperature. To do these computationally expensive calulations, I set up a computer infrastructure using Linux machines at the faculty.
