ROGER L. JACOBSON

EDUCATION

Ph.D:	1973	Geochemistry and Mineralogy, Pennsylvania State University
M.A.:	1968	Geology, University of Missouri - Columbia
B.A.:	1965	Geology, University of Minnesota - Duluth

PROFESSIONAL INTERESTS:

Dr. Jacobson is involved in conducting research primarily on chemical reactions and processes in surface water, groundwaters, and geothermal systems. His special research interests include chemical and isotope techniques for estimating recharge in arid terrains, water chemistry of deep carbonate aquifers, near surface chemical reactions in playas and caliche formation, subsurface radionuclide migration, ore deposit geochemistry, risk assessment, deep subsurface microgeology, and mountain watersheds. He also has participated in research and demonstration activities on renewable energy and sustainability. He has served on over 60 MS and PhD student committees in hydrogeology and geochemistry, and teaches graduate courses in Soil and Water Restoration and Isotope Hydrology. His present committee memberships which support these research interests include:

• City of South Lake Tahoe Technical Advisory Council.
  Help with design and evaluation of stream restoration.

  Washoe County Water Resources Technical Advisory Council

  Provide technical advice on water projects.

  Nevada Mining Task Force

  Work with other signatories of the Memorandum of Understanding to design and implement mine reclamation in Nevada.

  DOE Underground Test Area Technical Working Group

  Provide technical advice to DOE for underground testing projects

  DOE Nevada Environmental Research Park (NERP)

  Develop DOE needs statements and evaluate proposals from UNR and UNLV

PROFESSIONAL ACTIVITIES

• American Geophysical Union (AGU) member and reviewer
• Geochemical Society member and reviewer
• Member Nevada Test Site Development Corporation Board of Directors
