Dr. Schuessler's research interests lie in atomic physics and laser spectroscopy: on-line spectroscopy of short-lived isotopes, measurement of nuclear moments, spins nd charge distributions, cross-sections for spin dependent atomic collisions, ion storage spectroscopy and laser cooling, low energy ion and atom collisions, highly charged ion spectroscopy and Wigner crystals, attosecond and strong field physics, biomedical and atmospheric sensing. Professor Schuessler attended Rupert Charles University of Heidelberg, Germany, where he earned a Ph.D. degree in physics. After two years as assistant professor at the Technological University of Berlin, he was research assistant professor and research associate professor at the University of Washington. He joined Texas A&M as associate professor in 1969 and became a professor in 1981. For short intervals, he has been visiting associate professor at the University of Washington and visiting scientist at the University of Mainz and GSI in Germany. Professor Schuessler has been collaborating on research done at CERN in Geneva, Switzerland, and currently is performing experiments at RIKEN, Wakoshi, Japan, on-line at the ISAC mass separator at TRIUMF, Vancouver Canada, and the Max-Planck-Institute for Quantum Optics at Garching, Germany. He is a member of both the American and European Physical Societies and Sigma Xi.
