Dr Helena Greter is a biologist (MSc Ecology and Evolution) and epidemiologist (PhD) with over 12 years of professional experience in epidemiological research and impact evaluation related to neglected tropical diseases, human and animal health and integrated One Health surveillance. Since 2019, she is leading the competence center for epidemiological outbreak investigation KEA in Switzerland, focusing on food-associated diseases. Dr. Greter holds diverse qualitative and quantitative research skills and manages a broad portfolio of scientific and operational research activities focusing on health improvement for the hard-to-reach and vulnerable population groups. In addition, she is experienced in implementation research and quality assessment projects in complex environments, often in fragile contexts, particularly in the Sahel (Chad, Niger, Sudan), East Africa (Uganda, Tanzania), the Indian Ocean region. She is also providing technical assistance on complex projects such as integrated disease surveillance (Chad) and One Health networks (Comoros, Madagascar, Seychelles, Mauritius, La Réunion). She enjoys collaborations built on mutual trust with professionals from the health, agriculture, livestock and wildlife sectors and she is leading teams of people of various backgrounds and cultures with the necessary cultural sensitivity. She is actively involved in dissemination activities, and is also presented in publications in the peer-reviewed literature, at national and international conferences and, most important, to the stakeholders, communities and the populations concerned.
