Professional Activities:

I served on the full-time academic staff at Imperial College from 1994 until 2011, promoted to the position of Professor of Earthquake Risk Assessment in 2006. During my 17 years on the academic staff I supervised to successful completion 15 PhD students, and taught subjects related to Engineering Seismoloy, Risk Analysis, Professional Engineering Practice, and Energy, at undergraduate and Masters level. I also held a number of departmental posts, including Postgraduate Tutor (1996-2000), Senior Tutor (2001-2003) and Director of Undergraduate Studies (2004-2010). In the last role I coordinated the introduction of new 4-year MEng curriculum in Civil Engineeing.

In August 2013 I rejoined the academic staff on a part-time basis as a Senior Research Investigator and am engaged with some research in the Department and continue to publish (Web of Science h-index currently 44) as well as contributing to some teaching modules, I am mainly engaged in seismic hazard projects around the world, primarily for nuclear applications but also related to large dams, bridges and other major infrastructure projects, including the Panama Canal expansion. I am also working on some projects related to the hazard and risk due to induced seismicity. Details of these projects are in my CV.

Areas of Expertise:

Engineering Seismology: earthquake ground-motion characterisation and prediction; definition of earthquake actions for seismic design; seismic hazard assessment for natural and induced seismicity; earthquake loss estimation and risk analysis.
