Short CV
Frans van Geer is senior researcher at the Geological Survey of the Netherlands and adjunct professor at The Department of Physical Geography. He studied civil engineering at Delft University of technology (graduated in  1980). At the same university he received his PhD in 1987.  Since 1985 he is employed by TNO and since 2009 he is part-time adjunct professor at the University Utrecht. The focus in the work of Van Geer is on monitoring and uncertainty assessment in groundwater and soil processes. This includes time series analysis, geostatistics and data assimilation. Applications of these techniques mainly concern subsurface characterisation, ground water model calibration, the design of monitoring strategies, input response functions, trend detection and data quality control. Van Geer co-organized several workshops and symposia. He was (co)convenor of for example the EGS symposium in Hamburg, 1995, the EGS symposium in Den Haag, 1999, the workshop W7 of the IAHS-congress 2001, Maastricht and the EGU symposium in Vienna 2012. Currently he chairs the working group ‘time series analysis’ of the Dutch Hydrological Society (NHV).
