Thomas Udem, studied physics at the University of Giessen/Germany and at the University of Washington in Seattle/USA. In 1997 he received his PhD from the Ludwig-Maximilians-University Munich. After obtaining his Habilitation (tenure track) at the same University and a Postdoc at the National Institute for Standards and Technology (NIST) at Boulder/USA he became fellow of the Max-Planck Institute for Quantum Optics in Garching/Germany. Since 2016 he is a professor at the Ludwig-Maximilians-University Munich.
Thomas Udem's research interests are ultra precise laser spectroscopy, atomic physics, quantum optics and metrology. His main aim is to improve the spectroscopic accuracy of simple atoms such as hydrogen and hydrogen-like systems to test fundamental laws. His activities cover extreme ultraviolet frequency combs for spectroscopy of trappedions such as hydrogen like He as well as new calibration methods for precision astronomy.
