Personal Background

Richard Kraus, PhD, received his undergraduate degree in Physics at the University of Nevada, Reno. In 2008 he received an MPhil in Physics from the University of Cambridge, UK and in 2013 he received his M.S. in Applied Physics and PhD in Earth and Planetary Sciences from Harvard University. His 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.

Research Interests

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