Biography

Holger Mueller is a Professor at the University of California, Berkeley, specializing in atomic, molecular, and optical physics. He earned his undergraduate thesis in physics under the supervision of Jürgen Mlynek at the University of Konstanz, Germany. Following this, he completed his education at Humboldt-University in Berlin, with Achim Peters as his advisor. His career includes a postdoctoral fellowship in the group of Steven Chu at Stanford University. In July 2008, he joined the faculty in the physics department at UC Berkeley. His research advances techniques in atomic and molecular physics to probe nature with utmost sensitivity, including exploring matter-wave interferometry and phase-contrast electron microscopy. He is part of the Berkeley Physics Department and started various innovative projects, such as developing atom interferometers for measuring fundamental constants and investigating cryogenic electron microscopy to visualize biological macromolecules. Additionally, he is contributing towards NASA's goals of applying atomic physics in space environments. His contributions also include optical methods for non-invasive neuronal action potential detection, improving our understanding of brain functions.
