Biography

Themos Kallos completed his undergraduate degree in 2003 at the electrical and computer engineering department in the National and Technical University of Athens, Greece, and his Ph.D. degree in 2008 at the electrical engineering department of the University of Southern California in Los Angeles. His doctoral research work focused on using multiple electron bunches as a tool for the development of next-generation particle accelerators based on plasma wakefields. He was involved in experimentally demonstrating for the first time the acceleration of a trailing electron bunch in a high-gradient wakefield driven by a preceding bunch, through using bunches short enough to sample a small phase of the plasma wakes. This pioneering work was awarded with the 2009 Particle Accelerator Science and Technology Doctoral Student Award of the IEEE Nuclear and Plasma Science Society.

Themos Kallos is presently a post-doctoral researcher in the Queen Mary University of London, United Kingdom. His research interests include metamaterials, electromagnetic cloaking, FDTD & numerical techniques, antenna design, as well as high-energy physics, plasma-based particle accelerators, capillary discharges and Particle-In-Cell simulations.
