Dr. Julie Newman

Assistant Professor

Ph.D., University of Rochester, 1993

Research specialty: biogeochemistry

Research:

  • Field and microstructural studies of crustal and upper mantle rocks
  • Mechanisms of strain localization
  • Fluid-rock interactions
  • Interactions between deformation and metamorphism
  • Determination of deformation processes, and conditions of deformation (pressure, temperature, stress, strain-rate) in crustal and upper mantle environments
  • Structure and tectonics of mid-ocean ridges
  • Geothermometry and microstructural investigations of deformed rocks from ridge-settings
  • Structure and tectonics of fold- and thrust- belts
  • Field mapping of structures, especially in cooperation with microstructural studies
  • Experimental investigation of mechanical and microstructural behavior of carbonates using high pressure gas apparatus. (Funded by NSF: Experimental Deformation of Dolomite and Mechanisms of Flow in the Calcium-Magnesium Carbonate System. June 1, 2001 - May 31, 2003)
  • Applications of electron microscopy and electron backscattered diffraction (EBSD) to geology
