Research

Professor Weinert is a condensed matter theorist whose research interests include:

• The investigation of the electronic and magnetic properties of complex materials — surfaces, interfaces, alloys, and nanostructured systems — from first-principles, with emphasis on phase stability, defects, transport, and nanostructures.
• The analysis and interpretation of experiments involving spectroscopies such as photoemission, Auger, x-ray absorption, and scanning tunneling spectroscopy, and experiments related to the growth and atomic structure as probed by electron microscopy and scanning probes.
• The development and use of advanced first-principles electronic structure methods to model and understand the properties of materials.

Biographical Sketch

Michael Weinert received a BA in Physics and Mathematics from Northwestern University (1976), a ScM (1977) from Brown University, and a PhD in Physics (1982) from Northwestern University. He was a member of the Condensed Matter Theory Group at Brookhaven National Laboratory from 1982 to 2001, and was a Visiting Scientist at the KFA-Juelich (1986-7) and a Visiting Professor at the University of Vienna (2010).

Since 2001 Professor Weinert has been at the University of Wisconsin-Milwaukee, where he is a Distinguished Professor and Director of the Laboratory for Surface Studies. He is a Fellow of the American Physical Society and of the Institute of Physics (U.K.), and previously was an Associate Editor of Physical Review B.

Further information regarding his research, including publications, can be found on the electronic structure group website.
