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
