Education

Ph.D., Environmental Systems Engineering

            Clemson University, August 1991

            Specialization: Hydrogeology

Dissertation title: “Ground water vulnerability assessment and agricultural chemical management policies in the South Carolina Piedmont.”

M.S., Biomedical Engineering

            The Ohio State University, December 1985

            Specialization: Bioengineering / Bioremediation

            Thesis title:  “Models of a biological process for mercury decontamination.”

B.S., Agricultural Engineering

            The Ohio State University, June 1983

 

Major Fields of Specialization

Primary interests include solid and hazardous waste management, in-situ bioremediation, hydrogeology, and glacial geomorphology. Research focus is on landfills, specifically both why older unlined landfills fail due to fractured subsurface materials and how to engineer a sustainable bioreactor landfill that biologically treats waste.

·        OSHA Certification: Health and Safety for Hazardous Waste Site Operations (40-hr)

·        OSHA Certification: Permit Required Confined Space Operations

·        OSHA Certification: Excavation and Trench Safety
