Biography in Brief: Dr. Ronald E. Waltz

Theoretical physicist Dr. Ron Waltz (figure 4) developed GYRO, an advanced software code for simulating turbulent transport in fusion plasmas, with his General Atomics colleague Dr. Jeff Candy. Dr. Waltz pioneered numerical simulations of turbulent transport from the early 1980s and the concept of equilibrium-scale E×B velocity shear stabilization. In the early 1990she developed a novel wind-tunnel-like extrapolation method for predicting tokamak reactor performance, and he produced the most widely used theory-based transport model in 1997.

Dr. Waltz received a combined bachelor's degree in both physics and mathematics from Purdue University in 1966 and a doctorate in physics from the University of Chicago in 1970. He conducted research in high-energy theoretical physics at the European Organization for Particle Physics (CERN) and at the Massachusetts Institute of Technology. He studied the atmospheric effects of nuclear weapons at Visidyne, Inc. before joining General Atomics in 1975. He currently manages the company's Turbulence and Transport Branch, Theory and Computational Science Division, Energy Group.

Since 1986 Dr. Waltz has served on the physics faculty at the University of California-San Diego. He was a distinguished visiting scholar at Nagoya University in Japan and at Australian National University and is an elected Fellow of the American Physical Society. An author of more than 100 scientific publications, he was also a member of the ITER Transport Modeling Group from 1995 to 1998.
