My background is in atmospheric science and I have specialized in climate science and in particular, the impacts of aviation on climate, for the last 24 years. I have considerable scientific project and personnel management experience and have led large international multi-institutional projects. I have particular skills in developing links between science and policy, and work at an international level, e.g. the European Commission, ICAO, UNEP, IMO, WMO, IPCC, and have long experience in international scientific assessments at e.g. IPCC, UNEP, ICAO, IMO, peer-reviewed publications.
