HIS PRIMARY RESEARCH INTEREST IS THE DEVELOPMENT OF MATHEMATICAL FORMULATIONS THAT ARE REQUIRED FOR STUDIES OF PLASMAS THAT HAVE A NON-TRIVIAL DEPENDENCE ON ALL THREE SPATIAL COORDINATES. Boozer was one of two recipients to receive the 2010 Hannes Alfvén Prize, the best-known European award in plasma physics. He was honored at the June 2010 conference of the Plasma Physics Division of the European Physical Society, along with his colleague Jürgen Nührenberg from the Max Planck Institute, for “outstanding work in the formulation of criteria allowing stellarators to improve fast particle and neoclassical energy confinement.”
