Dr. Butler is an assistant professor of structural and materials engineering at York University in the Lassonde School of Engineering. His research expertise focuses on developing, investigating and implementing sustainable and intelligent structures and material systems. He was awarded a Ph.D. from the University of Waterloo for his research work involving recycling of old concrete structures into new concrete which combined materials characterization, structural component testing and statistical analysis. Following his PhD, he worked as a structural engineer at Read Jones Christoffersen Consulting Engineers on the design of a wide variety of complex structures and consulted on several challenging concrete materials-related projects. He is an active member of the American Concrete Institute's Technical Committee 555 on Concrete with Recycled Materials and is a registered professional engineer (P.Eng.) in the Province of Ontario, Canada. Following his consulting work, Dr. Butler was a postdoctoral research associate at the University of Cambridge in the Centre for Smart Infrastructure and Construction (CSIC). As a researcher within the CSIC, he led research projects in the broad area of infrastructure sensing primarily related to bridges and prestressed concrete railway ties containing embedded fibre-optic sensor networks. In addition, he is interested in developing strengthening systems for concrete structures using textile reinforced cementitious matrix systems with embedded sensing capability. Dr. Butler has also been cross-appointed as a Group Leader at the Alan Turing Institute's program on Data-Centric Engineering. In this role, he has worked with data scientists and statisticians to explore how advanced data analytics combined with physics-based models can be used to better understand critical structures, next-generation materials and the long-term resiliency of our built environment. His research has involved numerous successful collaborations with industry and academic partners around the world including at the University of Cambridge, Imperial College London, the University of Pretoria, Harbin Institute of Technology and Waseda University. He has taught and supervised students at the University of Waterloo and at the University of Cambridge.
