In 2001 Robert started his Bachelor study applied Physics at “Saxon Enschede” after his MBO study electrical engineering at “Technisch College Ede” . For his Bachelor degree, he did his assignment with the former NBP group. Where he characterized an ultrasound detector, and designed a multiplexed digitizer for parallel readout of the detector array. After the Batchelor Robert started as a research engineer, where he designed and reviewing several detection schemes for the “Acousto-Optic Imaging in tissue” that enabled measurement of local light flux deep inside tissue. Parallel on this he worked in a second project were functionalized Gold NanoParticles (GNP) are used as a detector, his part was modifying the optical microscope for measurement of the GNP, by true color imaging, spectroscopy and AFM on a single platform. During these projects he gained knowledge on automation of experiments together combined of optics, cameras, laser systems, electronics and software, he joined the NBP group fulltime in april 2011. His personal interests moved from playing guitar and restoration of old motor bikes, to photography and traveling.

-Own Research in NBP-
Application of polarization with gold or silver nano-particles, the Surface Plasmon Resonance frequency is determined by the electrical field, controlling the electric field by linear polarization will give additional information as size and orientation will shift the color. The known response of color as function of the polarization angle, helps to confirm single binding events.
