Biography

Professor Thomas works in experimental and theoretical plasma physics. His research is focused on the physics and applications of high power laser interactions with plasma. When heated by lasers, highly non-equilibrium states of matter arise, where complex behavior such as collective wave-particle interactions is prevalent and only full kinetic descriptions of the particle distribution are valid. Light and plasma couple together strongly, leading to instabilities and nonlinear wave formation. At the highest intensities, quantum electrodynamic effects become important in determining the plasma dynamics. Applications of intense laser driven plasma include advanced, miniature particle accelerators, next generation photon sources and inertial fusion energy. Professor Thomas is part of the Center for Ultrafast Optical Science High Field Science group, using the HERCULES and Lambda-cubed very high power laser systems for investigating the physics of relativistic plasma.
