Biography

Starting his career in magnetic confinement fusion at UCLA, Prof. Gourdain moved to Cornell University after his Ph.D. to study matter under extreme conditions on the Cornell Beam Research Accelerator. Prof. Gourdain is now an Assistant Professor of Physics and Astronomy at the University of Rochester.  At UCLA, Prof. Gourdain built and operated the Electric Tokamak.  There he studied the stabilization of runaway confinement using fast ion pumping from ion cyclotron resonance.  He studied the impact of Hall effect on high energy density plasma jets at Cornell University. 

Research Overview

Extreme states of matter are most uncommon on Earth. However, they are quite common in the Universe and include all its visible matter, especially in the x-ray and gamma-ray ranges. As matter is pulled away from peaceful environments such as Earth or intergalactic space, it becomes stars, brown dwarves or even black holes. During this migration, it changes its physical properties. In turn these properties define the macroscopic scales of astrophysical systems and understanding universal mechanics requires knowing these properties.  Prof. Gourdain is creating such extreme states in his laboratory to try to understand how high energy densities change the fundamental interactions of matter. His research group uses pulsed systems (principally lasers and pulsed-power generators) to:

  • explore the fundamental laws of strongly interacting systems;
  • study the formation of flows and shocks under extreme conditions;
  • validate competing physical models by comparing numerical simulations to experimental measurements.
