Dr. Lawler's research interests focus on particle removal processes in water and wastewater-flocculation and coagulation, sedimentation and thickening, filtration, and low pressure membrane processes. Other interests include applications of water chemistry and chemical engineering to water treatment, interactions among treatment processes, and resource conservation and pollution prevention in industrial settings. His research often combines laboratory experiments and mathematical modeling. Dr. Lawler has won ten teaching awards, is a member of UT's Academy of Distinguished Teachers, and received the A.P. Black Award from the American Water Works Association for significant contributions to research on drinking water over an extended time period.
