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 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 analyzed diatoms reservoir and wetlands in Arkansas,
the 244 m deep Pingualuit Crater Lake in Nunavik. In 2012 I analyzed freshwater and brackish wetlands
from Arkansas and Mississippi for the National Assessment Program. Currently I am working on bio
assessment of streams in Connecticut using diatoms.
Scientific writing is one of my strengths. 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.

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.

The class Climate through Time (ENDY/GEOS/BIO 5063/GEOG410V) is a paleoclimatology class
which I have taught four times to graduate students from the interdisciplinary Environmental
Dynamics and Biology PhD program as well as to MA geography and MS geology students.

I developed and taught a new graduate class in Fall 2010 entitled Ecology and Taxonomy of Algae
(GEOL 580V). The class served Environmental Dynamics and Biology students and two female
bioengineering students, who specialized on the development of algae fuel.
