Research, Teaching, and Applied Professional Practice
Dr. Yen’s research, teaching, and professional work focus on integrating environmental engineering practice, regulatory governance, and technology law.
His doctoral research investigated FeAl + DMSO-mediated degradation of PFOA in simulated wafer fabrication wastewater, with emphasis on advanced wastewater treatment and interfacial reaction mechanisms. Building on his experience in semiconductor manufacturing, environmental permitting, government administration, and independent professional engineering practice, Dr. Yen continues to develop applied perspectives on high-tech industrial water management, wastewater treatment, and environmental decision-making.
Dr. Yen has also served as an adjunct instructor, industry mentor, and Assistant Professor-level Technical Specialist at the National University of Kaohsiung. His teaching emphasizes the integration of environmental regulations, engineering project implementation, and industrial case studies. The courses he taught received Excellent Course Awards in 2015 and 2022.
