In Detail

Gabrielle works as an advisor at boardroom-level with a wide range of companies, helping to broker cross-sectoral collaborations and turn good intentions into real action on the ground. She has presented dozens of TV and radio programs for the BBC, reporting from all seven continents and has been Climate Change Editor at Nature and Features Editor at New Scientist and has written very extensively for many international newspapers and magazines, including The Economist, Prospect, The Wall Street Journal and The New York Times. She has a PhD from Cambridge University and has taught at both Cambridge and Princeton Universities. A self-confessed "ice addict" Gabrielle has made more than a dozen trips to both poles. She has also climbed trees in the Amazon rainforest and flown in zero gravity.


The world is facing systemic challenges on an unprecedented scale, both public and private institutions are trapped in silos, with short-term and short-sighted goals. Gabrielle works at the boundaries between these silos. Outside of unique ideas and companies to invest in, Gabrielle clearly believes that there is hope still in the face of this emergency and while we endeavour to save it, there are business opportunities to capitalise on along the way.
