Science Lead

Libby leads our team on Science, helping us to understand and communicate the real impact we are having on the world around us. She's a Master in Oceanography, has done several research studies on microplastics AND is a champion sailor. By 13 years old, Libby was competing in sailing across the UK and became the youngest ever person to win a National Championship race in the double-handed Enterprise dinghy class.

She is very passionate about environmental protection & impact investing. Sandra founded #Up2degrees, a movement that successfully lobbied the Singaporean government to reduce the impact of aircon.
