During my 15 years’ experience in diatom taxonomy I studied diatoms from a wide range of water bodies: I analyzed modern diatoms from 105 hard water lakes located in Switzerland covering a total phosphorus gradient from 5 to 505 µg/L. I studied the seasonal succession of diatoms from 7 lakes located along an elevation gradient in the boreal forest in Quebec. I trained students analyzing diatoms from a reservoir and wetlands in Arkansas and the 244 m deep Pingualuit Crater Lake in Nunavik. Recently I completed diatom identification and enumeration from freshwater and brackish wetlands from Arkansas and Mississippi for the National Assessment Program.

I am committed to high consistency in diatom taxonomy and to advancement of diatoms as bioindicators. Representative of this commitment are following publications: A new approach to reduce secondary gradients in training sets (Paleo3 2006), the use of sub annual samples for training sets (JOPL, 2007), the characterisation and application of ecomorphs (Freshwater Biology, 2001) and the description of a new extinct Cyclotella pingualutii that can be used as a chrono marker (Diatom Research, 2012). In order to advance diatoms as indicators of fluvial changes I hosted the first international PAGES Floodplain Lake workshop in collaboration with Peter Gell and Roland Hall in 2010 (EOS, 2011).

Scientific writing is one of my strength. I published or coauthored 15 peer reviewed articles. I authored or coauthored 10 grant proposals. Seven were funded (NSF, 2x USGS, CFCAS, SNSF, ABI, Leopoldina) and the three unfunded proposals to EPA and NSF (2) were ranked highly. In total I raised funding of $1.4M.
