Holger Müller has been elected as a 2019 Fellow of the American Physical Society (APS). An associate professor of physics at UC Berkeley and a faculty scientist in Molecular Biophysics and Integrated Bioimaging (MBIB), he was nominated by the APS Topical Group Precision Measurement & Fundamental Constants. Müller, whose worked is premised on the notion that precision measurements of fundamental quantities can help address the great challenges facing physicists, was cited “for advances in the manipulation of matter waves, including their application to precision measurement of the fine structure constant, to constraint on forces from light scalar fields posited to be dark energy candidates, and to the development of a phase plate for electron microscopy.”
