  • Inland Navigation Economic Modeling
  • Public Transit Benefits
  • Energy Economics
  • Environmental Economics
  • Automobile Materials
  • Water/Energy Nexus
  • Life Cycle Analysis
  • Recycling Plastics Waste

Current or Recent Work:

  • Led the development of the Ohio River Navigation Investment Model (ORNIM) for the U.S. Army Corps of Engineers (Corps). ORNIM is a large computer model to assist the Corps in making optimal investment decisions about new construction, rehab, and maintenance over a long-term horizon.
  • Led an economic assessment of benefits of potential infrastructure improvements to the U.S. Army Corps of Engineer’s, Upper Mississippi and Illinois Waterway System.
  • Led a study sponsored by the Tennessee Department of Transportation to estimate the benefits of public transit in Tennessee. The study addressed all direct and indirect benefits of both urban and rural transit.
  • Modeling economic interactions between water and energy as applied to transportation, energy security, and economic development.
