Research Interests

Richard Kraus's thesis research was on the thermodynamics of planetary impact events with a focus on impact induced vaporization. In September of 2013 he joined the HED Shock Physics group at LLNL as a Lawrence Postdoctoral Fellow. His research interests include

  • Entropy generation during shock and shockless compression
  • Equation of state development
  • Viscosity and strength at high pressure and temperature conditions
