Christian Gabriel Theiler
BiographyChristian Theiler obtained his master’s degree in physics from ETH Zurich in 2007 and his PhD from EPFL in 2011. He then joined MIT as a postdoctoral associate to work on the Alcator C-Mod tokamak. In 2014, he returned to EPFL as a EUROfusion fellow and, two years later, he was named Tenure Track Assistant Professor in Plasma Physics at EPFL.
Christian’s research focuses on tokamak boundary physics and related diagnostic techniques. He has contributed to the understanding of the formation, propagation, and control of turbulent plasma structures, called blobs, and gained new insights on the structure of transport barriers in the plasma periphery in different high-confinement regimes. Currently, he is focusing on detachment physics and turbulence characteristics in alternative divertor magnetic geometries.
