Profile
Professor Brownjohn joined the University of Sheffield in 2005 after periods at University of Bristol (1984-1992), Nanyang Technological University Singapore (1992-2004) and University of Plymouth (2004-2005). His academic career has revolved around experimental assessment of the performance of a range of civil structures, using full-scale dynamic testing, long-term monitoring and shaking table testing.
His present research and professional interests include wind engineering, earthquake engineering, structural health monitoring (SHM), finite element model updating, vibration serviceability, system identification and biomechanics. He has published in all these areas in a number of journals. His experience with ambient vibration testing and operational modal analysis using minimal portable equipment is a complement to the forced vibration testing approach traditionally used by the Vibration Engineering Section, of which he is a member.
Professor Brownjohn is involved in promoting developments in structural health monitoring through involvement in the International Society for Structural Health monitoring of Intelligent Infrastructure (ISHMII), the EU funded thematic network on Structural Assessment, Monitoring and Control (SAMCO) and the ASCE Committee on Structural Identification of Constructed Systems.
Professor Brownjohn is responsible for development and promotion of the Earthquake and Civil Engineering Dynamics (ECED) MSc course and is a founding director of Full Scale Dynamics Ltd, a University spin-out company.
