Biography:

Professor Tim Ibell received his BSc (Civil Engineering) from the University of Cape Town and his PhD in Structural Engineering from the University of Cambridge.  After 5 years in industry and as a post-doctoral fellow, Tim joined the Department of Architecture and Civil Engineering at the University of Bath, UK, where he was subsequently promoted through to Professor, Head of Department and Associate Dean for Research in the Faculty of Engineering and Design.  Tim was President of the Institution of Structural Engineers (IStructE) in 2015, and he is a Fellow of the Royal Academy of Engineering.  His research includes the use of fabric to form extraordinary concrete structures and the monitoring of loadings, structural behaviour and user experience in buildings to drive better design. He has a passion for education in structural engineering design, and he won the University of Bath's main teaching award in 2008 while Head of Department. In September 2017, Tim took up the Sir Kirby Laing Professorship of Civil Engineering at the University of Cambridge.

Research Interests

My key research interests lie in innovative construction of concrete structures using flexible formwork systems, and in the monitoring of buildings to determine what real loadings we should be assuming in design and also to investigate the connection between structural behaviour (sway and vibrations) and user experience (including productivity and wellbeing).

Research Supervision

I supervise PhD students in fields related to my research interests.

Teaching

I teach 1B Structures and Prestressed Concrete. I am a Fellow of Churchill College, where I supervise 1A Structures, 1A Mechanics and 1B Structures. My philosophy in education is to exploit the extraordinarily creative profession of structural engineering in every aspect of the learning experience, and to ensure that students are holistic in outlook as this is the cornerstone of great engineering.

Other Professional Activities

I am on the Boards of the Institution of Structural Engineers, Thomas Telford Ltd and The Ove Arup Foundation. I sit on the Education Committee of the Royal Academy of Engineering, and I am involved with RAEng Research Fellowship reviews.
