Dr. Walter Den joined the Department of Science and Mathematics at Texas A&M University-San Antonio as a Professor in 2018. Before arriving San Antonio, Dr. Den was a faculty member at Tunghai University (Taiwan) for 16 years. Academically, one of the responsibilities in his previous post was to network with the higher education community internationally. As a result, Dr. Den has accumulated an abundance of experience working with international programs in both the educational front and research front.
Dr. Den has over 15 years of experience developing water and wastewater purification technologies spanning across electro-chemical and electro-physical processes, membrane filtration processes, and microbial oxidation-adsorption processes. He has been active in working with industry to help boost water-use efficiency in various manufacturing sectors. Recently, he has focused on investigating the water-energy nexus and uses the concept to optimize industrial process water networks. He has served as a member of a consulting panel to help the chip-making industry in Taiwan identify the potential opportunities to reduce water consumption, worked with fabs to achieve water efficiency goals and acted as a consultant for Singapore's Public Utility Board to launch a similar project. He has also served as an expert consultant for water supply agencies and river conservation groups. His goal is to provide a holistic view of water treatment and reclamation by considering important factors such as cost, energy intensity, greenhouse gas emission, solid waste generation, and toxicity. Besides, Dr. Den's works have also involved the environmental quality control for various types of environments, arranging from industrial discharge, workplace environment, to specialized spaces such as semiconductor cleanrooms and medical settings.
Dr. Den received his master's degree and Ph.D. in Civil and Environmental Engineering from the University of Southern California, and a bachelor's degree in Mechanical Engineering from the University of California, Santa Barbara.
