Background and Research Interests

Ron Soltz’s thesis research focused on measuring space-time evolution of relativistic heavy ion collisions to constrain the properties of Quark-Gluon Plasma (QGP) and motivated his later work on calculating the quantum chromodynamics (QCD) equation of state for insertion into hydrodynamic models of the QGP. He has worked on the Pioneering High Energy Nuclear Interaction eXperiment (PHENIX) at the Relativistic Heavy Ion Collider and is now working the sPHENIX successor experiment. His interest in comparing theoretical models has led to his participation in the Jet Energy-Loss Tomography with a Statistically and Computationally Advanced Program Envelope (JETSCAPE) collaboration, which seeks to constrain jet energy loss parameters through model-to-data comparisons.

Soltz’s research interests include relativistic heavy ion physics, QCD thermodynamics, and topics in nuclear security related to non-proliferation and treaty verification. His interest in nuclear security has led to work on detecting nuclear material through neutron time correlations and work on the satellite detection of nuclear detonations.
