  Hussain Bahia

  Professor

  Hussain U. Bahia, PhD is a professor of civil and environmental engineering at the University of Wisconsin—Madison where he directs the Modified Asphalt Research Center. His current research and teaching focuses on pavement material and design, particularly on modified asphalts and asphalt mixes. Bahia has been the Technical Director of the Wisconsin Highway Research Program.

  James Tinjum

  Associate Professor

  James M. Tinjum, PE, PhD, F.ASCE, is an Associate Professor and outgoing Director of the Geological Engineering Program at the University of Wisconsin–Madison. Dr. Tinjum has 35 years of solid waste experience, beginning in 1990. Prior to his engagement as a faculty member at UW–Madison in 2008, he worked for 15 years in industry for prominent engineer-procure-construct firms and a Fortune 50 company. He has specialized technical knowledge in geoenvironmental and remediation engineering for landfills with industrial waste (lime kiln dust, cement kiln dust, foundry residuals, paper mill sludge, coal combustion residuals), municipal solid waste (particularly landfill liner and cover systems and the monitoring, recovery, and value-added use of landfill gases), and hazardous waste. He conducts research in waste geotechnics and waste containment systems; the beneficial reuse of industrial byproducts (e.g., for subgrade improvement and cementitious stabilization of pavement layers); life cycle environmental analysis of geo systems; remediation of contaminated sites; and fate and transport of landfill gas emissions. Dr. Tinjum developed these interests not only through industry practice and applied research, but also through discussions and interactions with practitioners participating in his nationally/internationally attended engineering short course programs. In applied practice, Dr. Tinjum has participated in nearly 100 solid waste projects.
