Prof. JULIAN J. BOMMER

Julian Bommer is Professor of Earthquake Risk Assessment at Imperial College. The principal focus of his research is the characterization and prediction of strong ground-motion parameters for seismic design and for earthquake loss assessment. He is a member of Project Team 1 for the definition of seismic sctions in Eurocode 8. He has participated in several field investigations of the effects of damaging earthquakes around the world and has worked extensively on seismic hazard and risk in Central America. From 2000-2002 he was Chairman of SECED, the UK member of the European and International Associations for Earthquake Engineering. Dr Bommer also serves as a consultant on earthquake hazard issues to several UK engineering and reinsurance companies on projects worldwide. Further information can be found here.
