Barbara is working as a Senior Lecturer in Agrihealth at the RVC in collaboration with colleagues from the Leverhulme Centre for Integrative Research on Agriculture and Health (LCIRAH). She has a strong interest in applying integrated approaches to health to understand better 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.

Since 2012 she has been working (first as a Post-Doctoral Fellow and then as a lecturer/senior lecturer in Agrihealth) for the Leverhulme Centre for Integrative Research on Agriculture and Health (LCIRAH) at the Royal Veterinary College. During that time she also obtained a Postgraduate Certificate in Veterinary Education.

Barbara's main area of interest is the integration of economic, social and epidemiological aspects in animal disease mitigation to provide practical and feasible tools that support decision-makers in the efficient allocation of resources. She is particularly committed to the development of interdisciplinary frameworks that support appropriate surveillance and intervention programmes for the control of foodborne and zoonotic diseases in food systems both in the North and the South. Her research and engagement activities can be summarised in four main streams:

  1. Economics of animal health surveillance: Elaboration of conceptual and theoretical foundations for the (economic) evaluation of surveillance, development of practical tools for evaluation, and application to national and international case studies.
  2. Food systems approach to disease epidemiology and management including nutrition: Use of a holistic and interdisciplinary approach to understand how food system practices and change impact on foodborne and zoonotic disease risks as well as food and nutrition security and how these can be managed in a sustainable manner.
  3. Economics of animal disease management: Economic evaluation to assess the economic efficiency and feasibility of management options for production and zoonotic diseases.
  4. Evaluation of One Health: Conceptualisation of key characteristics of One Health, development of standardised evaluation protocols based on key indicators and systems thinking, application of frameworks to case studies to investigate the potential added value of One Health. She is the coordinator of the international Network for Evaluation of One Health (NEOH) 

Barbara is the leader of the RVC research group Safe and Sustainable Food.

She regularly acts as a reviewer for a range of peer-reviewed journals and funding bodies and is a visiting editor to the journal Infection Ecology and Epidemiology.

Barbara's publications include peer-reviewed papers,book chapters and articles in lay magazines on: 1) Economics of animal health surveillance; 2) Food systems approach to disease management including nutrition; 3) Economics of animal disease management; and 4) Evaluation of One Health.
