Expertise
My work is focused on the test and development of oceanographic in situ sensors, and here mostly chemical in situ sensors. I have worked on optical instruments, wet chemical analysers and microelectrode sensors.
On the topic of in situ sensors I organized, together with Prof. Gwyn Griffiths, NOCS, UK and Prof. Tommy Dickey, UCSB, USA the workshop OceanSensors08 in Warnemünde.
