Prof. Dr. Jae Park | Wastewater Treatment | Best Researcher Award

Professor Emiritus | The University of Univ. of  Wisconsin-Madison | United States

Professor Jae Kwang Park is a leading researcher in Civil and Environmental Engineering, whose scholarly work has significantly advanced the understanding of environmental pollution control, contaminant transport, and sustainable waste and water management systems. His research has focused extensively on the mechanisms governing pollutant dispersion, sorption, and permeation in aquatic and subsurface environments. By integrating principles of hydrodynamics, environmental chemistry, and material science, he has provided deep insights into the fate and transport of organic and inorganic contaminants across engineered and natural barriers. His studies on pollutant dispersion in estuarine systems, for instance, have produced foundational models for analyzing tidal mixing, stratified flow behavior, and mass transport processes that are crucial to understanding pollutant migration in coastal waters.In the field of wastewater and solid waste management, his contributions include the development of advanced treatment technologies using ozonation, photocatalytic oxidation, and membrane filtration to remove persistent organic pollutants. His work on the permeation of volatile organic compounds through geomembranes, polymeric pipes, and landfill liners has been pivotal in assessing the long-term performance of containment systems, directly influencing design standards and environmental protection regulations. He has also explored the use of recycled and synthetic materials, such as shredded tires and geomembranes, for the mitigation of contaminant movement in landfills, bridging the gap between waste reuse and environmental safety.Professor Park’s interdisciplinary research extends to understanding microbiologically influenced corrosion, pyrolysis kinetics of rubber materials, and thermodynamic modeling of sorption in polymers, reflecting his commitment to solving multifaceted environmental engineering challenges through innovative methodologies. His body of work demonstrates both theoretical depth and practical relevance, providing valuable tools for environmental monitoring, infrastructure safety, and pollution prevention.
