Xueqiao Xu is a theoretical and computational plasma physicist with general interests in plasma physics, fluid mechanics, statistical mechanics, and parallel computing. Specific plasma physics experience: particle simulation, continuum simulation, fluid simulation, linear and nonlinear theory of micro-instabilities, turbulence, transport, and boundary plasma physics. Specific achievements include: (1) Developed the BOUT two-fluid edge turbulence code; (2) Lead physics developer for 5D continuum edge gyrokinetic code TEMPEST; (3) Co-invented new Monte Carlo scheme for usual gyro-kinetic δf particle-in-cell plasma micro-turbulence simulations for modeling Coulomb collisions. Over 60 refereed publications.
