Curriculum Vitae

 

Academic Interests and Accomplishments:

Sonja Hausmann joined our faculty in August 2006 as Assistant Professor. After Sonja defended her PhD thesis at the University of Berne, Switzerland in 2001, she worked as postdoctoral researcher at the Universtiy Laval, Canada from 2002-2006. Her primary scientific interest is paleolimnology, the examination of past environmental changes archived in lake sediments. Climate and human activities influence the water chemistry and physical parameters of lakes, and aquatic organisms respond to these changes and get deposited on the lake bottom. Modern process studies help to understand the ecological preferences of the individual taxa. In a second step, biological remains of aquatic organisms deposited in lake sediments can be used to reconstruct past environmental conditions quantitatively. Sonja and her group work with diatoms and collaborate with other researchers that study pollen, grainsize, paleomagnetics, chironomids, paleopigments and pollen. 

Current projects that Sonja, her students, and colleagues are working on include paleo-flood history of the Congaree River flood plain in the Congaree National Park, spatial and historical distribution of geosmin and MIB producers in Beaver Reservoir, NW Arkansas, and a paleolimnological study of the Arctic Impact Crater lake Pingualuit in northern Quebec, Canada. Sediments of Pingualuiy taken in May 2007 indicate interglacial cycles in sediments.

Pingualuit Crater Lake Project

Planning is underway for an international continental drilling program (ICDP) of the Crater Lake Potrok Aike in Patagonia.

Sonja is teaching Conservation of Natural Resources (GEOG 3003), Paleoclimatology (ENDY 5063), and Assessment of Water Quality (ENDY 6023). She is supervising doctoral students Ruchi Battacharya and Byron Winston and the postdoctoral researcher Jessica Black who defended her PhD at Instaar in Boulder, Colorado in June 2006.

Personal Information:

I live with my husband and our two cats close to the campus. I like biking to work. If I do not work I play with the cats or practice yoga. I also enjoy water coloring and pottery.
