Gilliss Dyer


Lead Scientist and Department Head of Matter in Extreme Conditions SRD at LCLS at SLAC National Accelerator Laboratory

Dr. Gilliss Dyer is a Lead Scientist at SLAC National Accelerator Laboratory and Department Head of Matter in Extreme Conditions in the Science, Research, and Development division of LCLS. He leads the MEC instrument team, which is dedicated to supporting the user programs of LCLS and LaserNetUS and developing new scientific capabilities and techniques in the science of high energy density, dynamic materials, and plasmas, particularly those making use of the LCLS X-ray source. Dr. Dyer earned his BA in Mathematics and Physics from New College of Florida and his PhD in Physics at the University of Texas, Austin. His professional background includes extensive work in the development and use of multi-terawatt and petawatt high energy density laser plasma experimental capabilities, as well as the development and construction of the high power chirped pulse amplification lasers.
