Roy Alexander (Alex) Tinguely

Research Scientist


Alex Tinguely is a PhD candidate in the MIT Department of Physics and conducts research at the Plasma Science and Fusion Center. Under the supervision of Dr. Robert Granetz and Dr. Earl Marmar, Alex studies the physics of tokamak plasma disruptions, during which plasmas rapidly terminate. His thesis project focuses on the evolution of relativistic "runaway" electrons which emit visible synchrotron radiation and can be generated during disruptions. Ultimately, Alex's goal is to predict and avoid (or mitigate) both runaway electrons and disruptions as they can damage and halt the operation of fusion devices. In his spare time, Alex dabbles in the fields of transformation optics and optical black holes.
