Biology study, University of Groningen. (Plantphysiology, medical microbiology: biofilms, molecular microbiology: bioenergetics) Ph.D., University of Amsterdam, Laboratory of Chemical Engineering, department of Bioprocess Engineering (1991). Post doc at the Biotechnological Centre of the University of Amsterdam (1991-1992) Research Scientist at Center for Biofilm Engineering, Montana State University, Bozeman, USA (1992-1994) Research Scientist at Laboratory for Microbial Ecology, University of Gent, Belgium (August 1994-January 1995) Research Scientist at Max Planck Institute for Marine Microbiology, Microsensor Group, Bremen, Germany (1995-1999). Leader of the Microsensor Group since May 1999. Research interests The central questions in microbial ecology: which organisms are present, what are they doing, and how are they controlled. I focus on benthic microbiology, so of bacteria that are adhered in biofilms, microbial mats or sediments. Particularly interesting I find the question how mass transfer controls microbial activities and community composition. For this we combine functional microanalyses (microsensors, isotope labeling, geochemistry) and molecular analyses on 16s-DNA and RNA for community analyses, as well as functional gene studies. Current research subjects are -photosynthesis and respiration in benthic photosynthetic systems (such as stromatolites and microbial mats) -effects ocean acidification on main element cycling via benthic processes, and consequences for microbial diversity -degradation pathways and transport mechanisms in intertidal permeable sands -habitat structures in deep-sea cold seeps -coupling of nitrogen and sulfur cycling (Beggiatoa and other sulfur oxidizers) Over 180 publications in peer reviewed journals on ecophysiology and method development (microsensors).
