updated Jan 13, 2015PROFILE
Dr. Sonja Hausmann joined the Phycology Section of the Patrick Center for Environmental Research in 2013 with 16 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.

TEACHING at the University of Arkansas
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.
