Dr. James W. Bunger has devoted his entire career to developing the science and engineering for producing substitute fuels from unconventional resources such as oil shale and oil sands. His early work focused on the composition and chemistry of upgrading the raw material to specification fuels. He was one of the co-founders of Red Leaf Resources, Inc. In work conducted for Red Leaf he has used his knowledge of chemistry and process design to identify effective and energy-efficient approaches to retorting of oil shale to produce liquid products. His knowledge of both the science and engineering has been instrumental in designing and interpreting process results from the laboratory and field operations. BSc Chemistry, University of Wyoming, 1968. PhD. Fuels Engineering, University of Utah, 1979.
