Research Interests

  • Experimental Physics – Physics at High Pressures, Material Properties (EOS, Phase Transitions, Transition Kinetics & Metastability), Novel Materials Synthesis and Characterization, IR, Visible and Raman Spectroscopies, X-Ray Scattering (Diffraction & Spectroscopy), Cryogenics
  • William Evans’ research covers a broad range of subjects aimed at understanding the physics and chemistry of materials under extreme conditions (pressure, temperature, strain rate,…). These activities include investigation of kinetic processes and phase transformations in molecular solids and metals; characterization of metals and molecular solids under high-pressure/temperature conditions; synthesis and characterization of novel technological materials.
  • His experimental activities involve several techniques such as ultrahigh-pressure diamond anvil cell work and associated diagnostics; micro-optical probing techniques such as Raman spectroscopy, visible absorption/transmission, and IR spectroscopy; X-ray scattering - diffraction and spectroscopy (inelastic scattering techniques). William has been employees at LLNL since 1995. He received his B.Sc. (Physics) from the California Institute of Technology and his S.M and Ph.D. (Applied Physics) from Harvard University. He is a member of the American Physical Society, American Chemical Society, Optical Society of America, Tau Beta Pi Honors Society, and often serves as a science fair judge.
