Debbie Callahan (BS '85) is the Associate Division Leader for Inertial Confinement Fusion Target Design at Lawrence Livermore National Lab. She was elected as a fellow of the American Physical Society in the division of Plasma Physics in 2014 for predicting and demonstrating the technique of laser scatter on self-generated plasma-optics gratings that enables generation and redirection of high-energy laser beams important for indirect drive inertial confinement fusion and high-power laser-matter interactions. Her team was the first to obtain a "fuel gain" of greater than one in a laser-driven nuclear fusion experiment, which was recently named one of the top 10 physics breakthroughs of 2014 by Physics World
