PROFILE
I am an expert in quantitative reconstruction of environmental change inferred from lacustrine diatoms using multivariate statistical methods. Representative of my work are following publications: A new approach to reduce secondary gradients in training sets for total phosphorus inferred from lacustrine diatoms (Paleo3 2006), the use of sub annual samples for seasonal climate reconstruction inferred from diatoms (JOPL, 2007), the characterization and application of diatom ecomorphs (Freshwater Biology, 2001) and the description of a new extinct Cyclotella pingualutii that can be used as a chrono marker (Diatom Research, 2012). I use radioisotope dating (lead-210, CS-134) on a routine basis. I have 15 years’ experience in multi partner projects.
I am committed to high consistency in diatom taxonomy and to advancement of diatoms as bioindicators. During my 16 years’ experience in diatom taxonomy I studied diatoms from lakes (sediment samples and and sediment traps), rivers and streams (floodplain lakes and periphytic samples). I am contribution to the webbase diatom key Diatoms of the United States.

TEACHING
· The class Conservation of Natural Resources (GEOG 3003) is a science elective for a broad spectrum of students with diverse backgrounds from multiple colleges including the School of Architecture, Recreation, Business, Geosciences, Biology, etc. In total, I have taught this class ten times.
· I developed, and have taught four times, a class entitled Pollution of Lakes and Rivers (GEOS
4333/ENDY 6023/BIO 480/GEOG 410) where students develop an extended knowledge and understanding of contemporary and past human impact on aquatic ecosystems. This class serves master students in Geology and Geography and PhD students of the interdisciplinary Environmental Dynamics (ENDY) and the Biology Programs. The class is now considered part of the core for the Environmental Soil and Water Major.
