Susanne Stemmer is a materials scientist and physicist who serves as a Distinguished Professor in the Materials Department at the University of California, Santa Barbara (UCSB).

Research Susanne Stemmer's research focuses on the development of novel thin-film materials, high-resolution scanning transmission electron microscopy (STEM), and the study of strongly correlated electron systems. She has worked on quantum materials, including the observation of rare electronic states such as zero-field Wigner solids.

Education and career Stemmer earned her Diploma in Engineering and Materials Science from the Friedrich-Alexander University of Erlangen-Nuremberg in Germany. She subsequently obtained her Ph.D. from the University of Stuttgart.

Following her doctoral studies, she held research positions at the Max Planck Institute for Metals Research and the University of California, Berkeley, before joining the faculty at the University of Illinois at Chicago as an assistant professor. In 2002, she joined the Materials Department at UCSB.
