Ernest William Tollner is currently a professor at University of Georgia in the Department of Biological and Agricultural Engineering.


  • BSAE, 1972 Agricultural Engineering, University of Kentucky
  • MSAE, 1974 Agricultural Engineering, University of Kentucky – Water resources emphasis
  • Ph.D., 1981 Agricultural Engineering, Auburn University –Waste management and water resources

Professional Experience:

  • Professor, The University of Georgia (1991-Present)
  • Professor and Graduate Coordinator, The University of Georgia (1999-Present)
  • Associate Professor, The University of Georgia (1985-1991)
  • Assistant Professor, The University of Georgia (1981-1985)

Research Interests: The overall area of research is related to development of engineering analysis and solutions related with measurement and evaluation of nondestructive minimally invasive measurement concepts in selected agricultural systems and wetland systems. Specific interests include the development of a sediment concentration sensor for real time use. Hydraulic modeling of flows through wetlands is a current research interest as is Bioconversion research.
