I am a Chartered Civil Engineer. I was a traffic and revenue consultant for 15 years, conducting international toll road feasibility studies for private sector investors and public sector promoters. More recently I moved into financial services and was employed as a credit analyst with Standard & Poor's, working in the agency's Infrastructure Finance Ratings practice for five years. As a Director in the London-based transportation team I was responsible for credits in the road, rail, airport and bus sectors. My portfolio covered corporate issuers and structured finance transactions - typically project finance deals and securitisations. I hold a PhD from the Institute of Transport Studies at the University of Leeds. I am a Fellow of the Institution of Highways and Transportation and a Fellow of the Institution of Civil Engineers. I currently run my own specialist consultancy providing technical support services to institutional investors, insurance companies and infrastructure funds.
