The AMMM Research Group is dedicated to exploring the interrelationship between processing, microstructure, and properties in advanced metals through the application of multi-scale ex- and in-situ characterization techniques within the context of advanced manufacturing. Our primary research focus centers on the discovery, synthesis and innovative design of next generation high-performance materials by microstructure engineering, with a particular emphasis on the realm of the lightweight advanced metals and alloys.

We are looking for passionate and motivated undergraduate students, graduate students and postdoctoral researchers to join our group.
