Education
- Ph.D., Civil Engineering, The University of Texas at Austin, December 1987.
- M.S., Environmental and Water Resources Engineering, Vanderbilt University, Nashville, Tennessee, August 1982.
- B.E., Civil Engineering, Vanderbilt University, December 1980 (Magna Cum Laude).
Professional Interests
Adsorption, fate, transport and transformation of chemicals, particles and environmental pathogens in unit operations and the natural environment. Recently focusing on infrastructure security and sustainability issues. These issues include vulnerability assessment methodologies, analytical techniques and emergency response, remediation and recovery plans applied to water treatment, storage and distribution systems and wastewater collection and treatment systems.
