Autorenporträt

António J. Reis ibecame a Civil Engineer at IST - University of Lisbon in 1972 and obtained his Ph.D at the University of Waterloo in Canada in 1977. He was Science Research Fellow at the University of Surrey, UK, and Professor of Bridges and Structural Engineering at the University of Lisbon for more than 35 years. Reis was also Visiting Professor at EPFL Lausanne Switzerland in 2013 and 2015. In 1980, he established his own design office GRID where he is currently Technical Director and was responsible for the design of more than 200 bridges. The academic and design experience were always combined in developing and supervising research studies and innovative design aspects in the field of steel and concrete bridges, cable stayed bridges, long span roofs and stability of steel structures. A. Reis has design studies and projects in more than 20 countries, namely in Europe, Middle East and Africa and presented more than 150 publications. He received several awards at international level from IABSE, ECCS, ICE and Royal Academy of Sciences of Belgium. José J. Oliveira Pedro became a Civil Engineer at IST - University of Lisbon in 1991, concluding his Master's degree in 1995 and Ph.D in 2007, with the thesis "Structural analysis of composite steel-concrete cable-stayed bridges". He joined the Civil Engineering Department of IST in 1990, as a Student Lecturer, and is currently Assistant Professor of Bridges, Design of Structures and Special Structures. In 1999, he was Researcher at Liège University / Bureau d'Etudes Greisch and, in 2015, Visiting Professor at EPFL Lausanne. In 1991, he joined design office GRID Consulting Engineers, and since then is very much involved in the structural design of bridges and viaducts, stadiums, long span halls and other large structures. He is the author/ co-author of over seventy publications in scientific journals and conference proceedings. In 2013, he received the Baker medal, and in 2017 the John Henry Garrood King Medal, from the Institute of Civil Engineers, for the best paper published in Bridge Engineering journal.
