Lead, Bertarelli Foundation's Marine Science Programme
Marine conservation

Heather started working for ZSL (Zoological Society of London) in 1995, as a postdoctoral research scientist in the Institute of Zoology, curator of London Zoo Aquarium, Head of Marine and Freshwater Conservation and now as Senior Marine Technical Advisor and Lead of the Bertarelli Foundation's Marine Science Programme. Heather is also an Honorary Professor at the University of Exeter and a National Geographic Explorer.

During her career at ZSL, Heather has co-founded Project Seahorse in 1996; set up Net-Works, a novel community-based supply chain for discarded fishing nets that are recycled into carpet (now the social enterprise COAST-4C); and was science co-lead for National Geographic's 2019 Sea to Source: Ganges expedition. Since 2017, Heather has been the lead of the Bertarelli Foundation’s Marine Science Programme, a transdisciplinary research and conservation programme focused on the Indian Ocean, involving over 90 researchers from 24 institutions and 6 countries. This programme is an endorsed Action of the UN Decade of Ocean Science for Sustainable Development and has a strong focus on regional capacity building for marine science.
