| Biography in Brief: Dr. Ronald E. Waltz
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.
