Profile
Tim Ibell graduated with a PhD from the University of Cambridge in 1992 and, after a couple of years design experience, completed a post-doc at Cambridge before joining the Department of Architecture and Civil Engineering at the University of Bath in 1997. Tim was promoted to Professor (2003), Head of Department (2005) and Associate Dean of the Faculty (2008). He is Vice-President of the Institution of Structural Engineers.
In 2002, Tim spent a year in the US on a Fulbright Distinguished Scholar Award, working with Professor Tony Nanni. Since 2006, Tim has been a member of the EPSRC Peer Review College. He sits on three journal editorial boards, and on several IStructE committees, including Council, Executive Board, Membership (Chair), Education, Nominations, Resources and the Joint Board of Moderators. He is a Senator at the University of Bath. He has a passion for teaching, particularly at first-year level.
Research
Tim has a strong research interest in the structural behaviour and retrofit of concrete bridges and structures. In particular, Tim is interested in the realistic structural assessment of existing concrete bridges and he has a team of researchers looking at the use of fibre-reinforced polymers to reinforce and/or strengthen concrete structures. He also leads research into fabric-formed concrete structures and into the use of polymeric façades for retrofit. Blast resistance of structures (and mitigation) is a growing interest.
Tim and his team have been the recipients of five best journal-paper awards, including two from the Institution of Civil Engineers and three from the Institution of Structural Engineers.
