Stefan Bathe received his Ph. D. in experimental nuclear physics from the University of Muenster, Germany, in 2002.  He was a postdoctoral research scientist at the University of California, Riverside, from 2003-2007.  In 2008, he became a Scientific Staff Fellow of the RIKEN-BNL-Research Center at Brookhaven National Laboratory (BNL).  In 2010, Prof. Bathe joined the faculty of Baruch College as an Associate Professor.  From 2010 to 2015 he was jointly appointed as a Fellow of the RIKEN-BNL-Research Center at BNL.  Prof. Bathe is also a faculty member of the PhD Program in physics at the CUNY Graduate Center.


Prof. Bathe's research interest is in experimental high-energy nuclear physics.  He is a member of the PHENIX experiment at the Relativistic Heavy Ion Collider (RHIC) at BNL, an international collaboration of 500 scientists.  The experiment studies a new phase of strongly interacting matter, dubbed the Quark-Gluon Plasma (QGP), that emerges at extremely high temperature and density.  This is achieved by colliding heavy nuclei at relativistic energies and measuring the produced particles.

Prof. Bathe has worked on the measurement of neutral pions with electromagnetic calorimeters, which in 2001 led to the discovery of jet quenching in heavy ion collisions. In recent years, his group has focused on a new silicon vertex detector.  The detector identifies D and B mesons through measurement of their decay vertex, providing insight into the mechanisms of energy loss of partons in the Quark-Gluon Plasma. 

Prof. Bathe has taken a leading role in the experiment.  He served as Physics Working Group Convenor, Run Coordinator, Analysis Coordinator, and on the Executive Council and Institutional Board.

Prof. Bathe's research is sponsored by a grant from the Department of Energy.
