Faculty Profile for Dr. Keisuke Ikehata
Biography and EducationDr. Keisuke Ikehata is an Assistant Professor of Civil Engineering in the Ingram School of Engineering, Texas State University, San Marcos, Texas. Dr. Ikehata received his Ph.D. in Civil and Environmental Engineering from the University of Alberta, Edmonton, Alberta, Canada in 2003. In July 2019, he joined Texas State University as one of four founding members of the new Civil Engineering Program. Prior to joining Texas State University, Dr. Ikehata worked for more than eight years as a technical specialist/R&D manager at a water resources engineering firm in Orange County, California and eight years in academia in California, Alberta, and Kansas. Dr. Ikehata is a registered professional engineer (Environmental Engineer) in Arizona (PE) and Alberta (PEng) for more than 8 years.
Teaching InterestsDr. Ikehata's teaching interests are in water quality engineering, advanced treatment technologies, water and wastewater infrastructure design, sustainable stormwater facility design, including low-impact development and best management practices, desalination and water reuse.
Research InterestsDr. Ikehata is an expert in advanced water and wastewater treatment and sustainable water resources management, including water reuse, desalination, and stormwater management. He has led or been involved in more than 130 engineering, research, and R&D projects in the United States to develop, design, and evaluate, novel sustainable solutions for emerging water resources challenges, as well as contaminated site remediation, agricultural and industrial water management in the past 20 years.
