Marie has been a Technical Director with ENN for 17 years and is also a member of ENN’s Board of Trustees. Marie is the longstanding Co-Editor of ENN’s flagship technical publication, Field Exchange, overseeing significant growth in its impact, readership and authorship. Marie is ENN’s technical lead on a growing portfolio of work on the management of at risk mothers and infants under six months (MAMI) including on process evaluation of an upcoming randomised control trial in Ethiopia in a LSHTM/GOAL/Jimma University partnership.  She is also the coordinator of an established UN/NGO interagency collaboration on infant and young child feeding in emergencies (IFE Core Group), co-chair of the Wasting Thematic Working Group of the Global Assistance Mechanism on Nutrition (GTAM), and a member of the Council of Research & Technical Advice on Severe Acute Malnutrition (CORTASAM) of the No Wasted Lives Initiative.

Tanya Khara
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. As an integral member of the research team responsible for developing Community-based Management of Acute Malnutrition (CMAM) and subsequently driving the uptake of the approach within UNICEF, she was able to do exactly that. 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. At present, 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.
