Dr. Raithel received his Diploma and Ph.D. at the University of Munich, where he studied Rydberg atoms in external electric and magnetic fields and in cavity-QED systems based on high-Q superconducting microwave cavities. From 1995 to 1997, he researched as a fellow of the Alexander von Humboldt Foundation at NIST on atoms in optical lattices. He then became a professor of Physics at the University of Michigan. His present work includes Rydberg-atom spectroscopy in cold plasmas, electromagnetic-field sensing, cold atomic gases, guided atomic flows and Bose-Einstein condensation, and atom interferometry. Rydberg atoms form exotic molecules and are suitable for field sensing, high-precision spectroscopy, and fundamental physics studies. Raithel was an Associate Chair of U of M Physics from 2009-2013 and Secretary/Treasurer of the DAMOP division of the APS from 2011-2014. He is a co-founder of Rydberg Technologies Inc, Fellow of the APS, has ~160 peer-reviewed publications, and has presented at many national and international conferences. A complete publication list is readily available on Google Scholar. About thirty of his graduate students have received Ph.D. degrees and hold positions in academia, industry, and government.
