Founder and Chief Scientist, Origen

Co-founder, DryGro

Tim ran the Oxford Geoengineering Programme at the Oxford Martin School between 2010 and 2022. This multidisciplinary initiative assessed the technical, social and ethical issues associated with the full range of proposed Greenhouse Gas Removal and Solar Radiation Management techniques. He is a co-author of The Oxford Principles (Rayner et al., 2013) which proposed a governance framework for geoengineering research.

He is involved in two start-ups – Origen, which is developing a technology to decarbonise lime production and remove carbon dioxide from the air – and DryGro, which is developing technology to grow high-protein crops in arid environments using a fraction of the water required by conventional agriculture.
