Keynote Speakers for IJREWHS2026

Luis F. Restrepo is a Civil Engineer from the University of Medellín (Colombia) and a Specialist in Earthquake-Resistant Engineering from EAFIT University (Colombia). He earned a Master's degree in Seismic Engineering from the European School of Advanced Studies in Seismic Risk Reduction (ROSE School, Italy), a PhD in Earthquake Engineering from the University of Pavia (Italy), and a Master's degree in Mining Industry Management from the University of Viña del Mar (Chile).
Throughout his professional career, he has developed extensive expertise in seismic risk and hazard analysis, earthquake engineering, soil dynamics, structural and earthquake-resistant design, and the design of concrete dams (including gravity, arch and RCC), as well as earthfill and rockfill dams. His work also encompasses structural pathology, masonry structures and project management. He has contributed to the study and design of more than 35 dams worldwide and has been involved in the design of infrastructure projects such as bridges and tunnels, in addition to numerous seismic hazard studies conducted in Colombia and internationally.
Luis is the author or co-author of 29 publications in national and international journals and has over 15 years of experience as a university lecturer. He is a registered engineer in Colombia, Peru, and the United States, and currently serves as CEO of Integral Consulting Engineers.

Tetsuya Sumi graduated from the Department of Civil Engineering, Graduate School of Engineering, Kyoto University in 1985. He then worked for the Ministry of Construction of the Japanese government for 14 years. In 2009, he became a full Professor at the Water Resources Research Center, Disaster Prevention Research Institute. In 2024, he established a new laboratory focused on dam upgrading and reservoir sedimentation management, in collaboration with hydropower companies, consulting firms, and government research institutes.

His research areas include hydraulic engineering and dam engineering, with a particular emphasis on sediment management in rivers and reservoirs, river restoration, and dam operation. He currently serves as Vice President of ICOLD and Chair of the Asia-Pacific Club. He is also President of the Japan Society of Dam Engineers and Chair of the IAHR Japan Chapter.

Wei Wangru is an Associate Professor of Hydraulics and River dynamics at the State Key Laboratory of Hydraulics and Mountain River Engineering, Sichuan University. He has been awarded the Chang Jiang Scholars Program by the Ministry of Education of China. His primary area of expertise lies in hydraulic structures, encompassing both theoretical fundamentals and physical modelling. His research focuses on the complex mechanics of turbulent flows in high-head hydraulic structures, including air-water flow hydraulics, cavitation erosion and aeration protection, and flood discharge energy dissipation. The advanced technologies to which he has contributed, including energy dissipators, aerator devices and structural optimizations, underpin the hydraulic design of current engineering endeavors in China.
