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.
