Matt Hopkins

Bio

A critical part to the future of LTP science and application is the development of advanced computational models. Such models provide insight on physical and chemical phenomena that are otherwise diagnostically inaccessible. Matt Hopkins is internationally recognized for his work leading the development of new kinetic plasma models. Dr. Hopkins is a founding organizer of the International Workshop on the Mechanisms of Vacuum Arcs, is a member (and Treasurer) of the Permanent International Scientific Committee for ISDEIV, a committee member of many conferences, and part of the LXCat team.

Research Interests

  • Computational modeling and simulation of non-equilibrium plasma phenomena
  • Discharge physics: vacuum, low-pressure, atmospheric pressure, higher pressures, including surface (vacuum-insulator)
  • Surface coupling to plasmas: secondary yields from ion, electrons, photons
  • Electron and neutral surface emission (field, thermionic, etc.)
  • Verification and validation methods for plasma simulation, especially PIC-DSMC
