The Department of Physics at the University of Massachusetts Dartmouth, in collaboration with the University of Connecticut and the Naval Research Laboratory, is seeking one Postdoctoral Fellow to lead a project studying type Ia supernovae, incorporating newly-developed first-principles turbulently-driven detonation initiation models into three-dimensional full-star hydrodynamical simulations. All applicants should have strong high-performance computational skills. Knowledge of nuclear astrophysics, and experience with hydrodynamical models, turbulence modeling, nuclear networks, and radiative transfer on high-performance computers is a plus. The position is funded by a NASA collaborative study led by Drs. Robert Fisher (University of Massachusetts Dartmouth - UMassD), Alexei Poludnenko
