Research
Professor Schwander’s research focuses on the structure and function of biological macromolecules by analyzing snapshots obtained by x-rays and electron microscopy.
He is also a participant in BioXFEL, a Science and Technology Center (STC) established by the National Science Foundation in 2013 of eight U.S. research universities aimed at addressing the fundamental questions in biology at the molecular level.
Research Interests
Structure and dynamics of macromolecular assemblies, molecular machines, single-particles methods using X-ray Free-Electron Laser and cryo-Electron Microscopy, data mining of large data sets by Manifold Embedding, Tomography.
Biographical Sketch
Peter Schwander graduated with his PhD in Physics from the Swiss Federal Institute of Technology Zürich (ETHZ), the most prestigious university in Switzerland, and completed postdoctoral studies at AT&T Bell Laboratories in New Jersey. Dr. Schwander returned to Switzerland after completing his postdoctoral work and then joined IHP, a Leibniz Institute for Microelectronics in Frankfurt (Oder), Germany before joining UWM as a Senior Scientist and Adjunct Professor. He worked in that capacity for six years before being promoted to Associate Professor in 2014.
In addition to his academic appoints, Dr. Schwander has served as the Vice President for Research and Development at Lesswire AG in Germany.
