research overview
- One aspect of Dr. Romatschke's research focuses on the theoretical description of ultrarelatistic heavy-ion collisions as performed at experiments at the Relativistic Heavy-Ion Collider (RHIC) or the Large Hadron Collider (LHC), with the aim of getting a better understanding of the theory of strong interactions (Quantum Chromodynamics). Dr. Romatschke's expertise lies in using relativistic hydrodynamics to describe these systems, with the aim of extracting of material parameters such as shear and bulk viscosities of high temperature Quantum Chromodynamics. Complementary to this effort, Dr. Romatschke is studying efficient algorithms for relativistic fluid dynamics that can have applications in other fields, such as astrophysics. Another aspect of Dr. Romatschke's work focuses on using analytical Quantum Chromodynamics calculations to predict properties of neutron stars, such as their masses and radii.
