My work is focused on interrelationships of tourism, transport and sustainability. In the early 1990s, I started to study aviation and its contribution to climate change, later on including other transport modes such as car, bicycle, and e-scooter.

I am specifically interested in climate policy and transport governance; transport economics; urban planning; consumer cultures; and anything related to tourism and mobility. I am feeling most at home in interdisciplinary frameworks embracing geography, economics, sociology and psychology.

My work has been conducted in a wide range of cultural and geographical settings in the European Union, the Middle East, East Africa/Western Indian Ocean, and the Caribbean. I have also worked as a consultant on behalf of numerous governments and companies, as well as supranational organisations including UNWTO, UNEP, OECD, ETC, WRI, and World Bank.

My ambition is to contribute to basic and applied science, with the overall objective to develop solutions for a growing number of environmental problems.
