Ulrike Wegst studied physics at the University of Göttingen in Germany and received her Ph.D. in Engineering from the University of Cambridge in 1997 for analysis of the mechanical performance of natural materials. She worked on the CES Eco-Selector software before moving to the Institut National Polytechnique de Grenoble in France in 2000 and to the Max Planck Institute for Metals Research in Stuttgart, Germany in 2001. She has been a Faculty Guest Scientist at the Lawrence Berkeley National Laboratory and the Anne Stevens Assistant Professor at Drexel University. Dr. Wegst joined the faculty at Dartmouth in January 2012.

Ulrike G.K. Wegst's research interests include biological materials in nature as well as their applications for musical instruments and sports equipment, biomaterials, biomimetics (the systematic transfer of biological principles of function and efficiency to technology), materials for energy generation, and materials synthesis and selection. Fundamental to all is the understanding of structure-property-processing correlations. In particular, she and her group design and manufacture by freeze-casting ("ice-templating") novel hybrid materials with unusual combinations of structural, mechanical, optical, thermal, and electrical properties.
Dr. Wegst needs undergraduates who would enjoy working with her and her group on ideas and research that combine mechanics, materials science, biology, chemistry, and physics to formulate new and unexpected design paradigms for superior materials.
If you would like to:
- observe water freeze and shape materials to make tissue scaffolds for spinal cord and bone repair using ice-cream technology
- analyze and visualize the microscopic and three-dimensional inside view of biological material
- measure the mechanical properties of newly developed materials...
then please contact Dr. Wegst at email@example.com.
