Personal Background

Randolph Hood has been a staff physicist in condensed matter physics at Lawrence Livermore National Laboratory since January 1999. He received his BS degree from Northwestern University in Evanston, Illinois in 1989 and his PhD degree in condensed matter physics from the University of California at Berkeley in 1994. His graduate adviser was Leo Falicov and his thesis was entitled "Magnetic Metallic Multilayers" where he proposed a theory of the Giant Magnetoresistance of Magnetic Metallic Multilayers. These materials have since been utilized in magnetic hard drives allowing for their continued exponential growth in storage capacity. Dr. Hood then became a postdoctoral fellow at Georgia Tech University in Atlanta (1994-1996), where he developed an approach to use Quantum Monte Carlo to calculate the exchange and correlation density of realistic materials such as silicon which were compared with approximations widely used in implementations of density functional theory. From 1996-1998 he was a postdoctoral fellow at Cambridge University in Cambridge, England. At Cambridge he carried out Quantum Monte Carlo calculations of excitation energies of semiconductors and defects.
