Berndt Müller received his Ph.D. in 1973 from the Goethe University in Frankfurt, Germany, for research on electrons in strong electric fields. After postdoctoral appointments at Yale University and the University of Washington, he joined the Goethe University faculty in 1976. Since 1990 he has been a member of the Physics Department at Duke University, where he holds the position of James B. Duke professor. From 1999 to 2004 he served as Dean of the Natural Sciences; since 2008 has headed the Duke Center for Theoretical and Mathematical Sciences. He received the Jesse Beams award of the Southeastern section of the American Physical Society in 2007. In recent years, the main focus of his research activities has been on relativistic heavy-ion collisions and the physics of the quark-gluon plasma.
The STAR detector at RHIC has measured a signal that may indicate parity violation occurs in metastable regions of the superdense matter.
