Dr. Candy is a principal scientist in the Fusion Group at General Atomics. He is presently engaged in core plasma transport research, with primary focus on gyrokinetic and neoclassical theory, simulation and algorithms in parallel computing, and predictive transport modeling. Together with R.E. Waltz, he developed the GYRO code, widely regarded as the state-of-the-art in the field. Dr. Candy maintains a general but active interest in numerical methods, in particular those with application to plasma kinetic theory. In addition to theoretical and computational work, Dr. Candy has also designed, implemented and managed three Linux beowulf clusters. The most recent is a 116-processor Opteron/Infiniband system used by the GA theory group.

Dr. Candy received his Ph.D. in 1994 under the supervision of M.N. Rosenbluth. He was visiting scientist at the JET Joint Undertaking during 1995-96, and subsequently a postdoctoral fellow at the Institute for Fusion Studies in Texas from 1996-98, before coming to General Atomics in 1998. He has worked on a variety of topics in linear and nonlinear kinetic theory. Notably, he first pointed out the danger of very-high-n TAE modes in burning plasmas, predicted the existence of LSTAE modes (subsequently observed in experiments), and made the only self-consistent computations of alpha-particle transport in reactors due to TAE and fishbone modes. In 1989, he independently discovered the 4th-order explicit symplectic integrator.

He has received various Canadian awards, including 4 NSERC postgraduate fellowships, 2 NSERC postdoctoral scholarships, and the Sir James Lougheed Award of Distinction. In 2003, he was the inaugural recipient of the Rosenbluth award for fusion theory. He is also 2008 Jubileum Professor at Chalmers University.
