ENN Technical Director
Tanya joined ENN in 2017 bringing with her more than 20 years’ experience as a public health nutritionist spanning university research contexts, INGOs, Valid International, the UN, UK government, and as an independent consultant. She has an MSc in Public Health from the London School of Hygiene and Tropical Medicine and a BA in Human Science from Oxford University.
Tanya is driven by a desire to better shape and translate research into doable, effective and equitable programmes.

She subsequently broadened her focus, developing a number of technical reviews, exploring neglected areas in international nutrition, including maternal and adolescent nutrition, and the relationship between wasting and stunting, always highlighting key opportunities for improvements in programming and policy.
Tanya is ENN’s technical lead on our body of work on the relationship between Wasting and Stunting, including our USAID supported study in West Africa, the knowledge management and monitoring of the Global Technical Assistance Mechanism for Nutrition (GTAM), with whom she works closely with partners in UNICEF and World Vision, and also leads ENN’s resource forum for field practitioners, en-net.
