Dr. Sonja Hausmann joined the
Phycology Section of the
Patrick Center
for Environmental Research in 2013 with 15 years’ experience in multi partner
paleolimnological projects in Switzerland, Canada and the USA. She is an
expert at inferring environmental change from diatoms (single cell algae)
using multivariate statistical methods.
Her current research projects include the development of water quality criteria
for lakes and streams using diatoms. This work is performed in collaboration
with the NJ Department of Environmental Projection and the US Environmental
Protection Agency.
Subjects of representative publications are: A new approach to reduce
confounding variables in diatom calibration sets
(Paleo3,
2006), the use of sub annual samples for diatom-inferred wind activity (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 for the impact crater Lake Pingualuit in Nunavik
(Diatom Research, 2012). She has manuscript in progress about diatom-inferred
hydrological changes in wetlands and mercury deposition in reservoirs.
