About:

Research interests

Development of quick and reliable sample processing and analytical methods for geological applications. 

Elemental/calcium ratios in forams and corals to reconstruct climate changes. 

Anthropogenic and natural radionuclides for dating of sediments. 

Main tasks

SF-ICPMS

Maintainance of a sector field ICPMS (Element-2, ThermoFinnegan). Method development and routine analysis of traps/sediment/corals/forams. Quality control of data.  Automatization of data-processing with Program R. 

Lab

Lab coordinator of our GEO-labs. Projectleader of the renovation of the labs and offices. The acquisition (after a comparison study with standards) of instruments e.g. HR-ICP-MS, gamma and alpha spectrometry, particle size apparatus. Guiding students (HLO and MLO) and analysts.

Radionuclides

Specialist in short living low radio-active isotopes like lead-210 (alpha spectrometry) and radium-226, cesium-137 (gamma spectrometry). Quality control of data. Dating of sediment via modelling isotope profiles in Excel.

Particle characterisation

Specialist in grain size measurements (Coulter 

LS230), specific surface area (Micromeritcs Tristar) and scanning electron microscope.

XRF

Involved in quantitative XRF-corescanner of wet sediment cores.

Research cruises

Participation with sea going expeditions (ENAM94, OMEX95, Teluk Banten 1996,1998, 1999), Red river delta (2000) en Kalimantan (2006).
