Barbara is working as a Lecturer in Agrihealth with the Leverhulme Centre for Integrative Research on Agriculture and Health (LCIRAH). She has a strong interest in applying One Health or Ecohealth approaches to better understand food systems and how changes in those impact on food safety and food security and to improve the wellbeing of people and animals through better resource allocation

Barbara was born in Switzerland and graduated from the School of Veterinary Medicine at the University of Bern in 2002. Her doctoral thesis on the ‘Economic and epidemiological aspects of bovine neosporosis in Switzerland’ undertaken at the Swiss Federal Veterinary Office (2003-2005) received the ‘Faculty Award’ (Fakultätspreis) for the best veterinary medicine dissertation and the award from the Association of Bernese Female Academics (Vereinigung Bernischer Akademikerinnen).

From 2006 to 2007 she worked as a border veterinary inspector at the border inspection post in Basel, checking imports of live animals, animal products and by-products. She came to the RVC in April 2007 to work as a research assistant in Veterinary Public Health. From 2008 to 2011 she did a PhD on the economics of veterinary surveillance. During the same time, she obtained a Certificate of Higher Education in Economics from Birkbeck College, University of London.

Barbara’s main area of interest is the integration of epidemiological and economic aspects in animal disease mitigation. Both her dissertation and PhD aimed to support decision-making at the government level by providing practical tools to facilitate the efficient allocation of resources to current and potential mitigation programmes. In LCIRAH she is focusing on interdisciplinary frameworks that allow assessing both the impact of foodborne and zoonotic diseases on people in food systems and potential surveillance and intervention measures. Barbara has a strong interest in the economics of One Health and is contributing to the development of an evaluation framework for the concept.

Her research further includes economic assessments of mitigation strategies for zoonotic, foodborne and production diseases, which are either conceptual in nature (e.g. application of economic principles to surveillance; combining metrics from different disciplines to assess One Health), and/or disease centric (e.g. economic assessments of rabies control in Bali and Colombo City; integrated epidemiological and economic assessments of salmonellosis, neosporosis, bluetongue, bovine virus diarrhoea in Switzerland; economic assessment of emerging disease surveillance in the UK, impact assessment of Schmallenberg virus in the UK and France).
