Ana is currently a lecturer in Veterinary Public Health and part of the Veterinary Epidemiology, Economics and Public Health group. She divides her time between developing VPH teaching and research. Her main interests are foodborne diseases, zoonoses and antimicrobial resistance. 

Ana completed her Veterinary Medicine degree in 2001 in the Universidade Tecnica de Lisboa, Portugal. She initially worked as a veterinary surgeon in a companion animal and exotic pets practice in Milan, Italy with the support of the Leonardo da Vinci European program. 

In 2003, she moved to the UK and undertook a Official Veterinary Surgeon (OVS) course at the University of Glasgow. She worked for over 2 years in Food Safety in red and white meat slaughterhouses, in Scotland and the North of England. In 2005, to broaden her knowledge, she enrolled a residency program in Veterinary Public Health by the University of Glasgow Faculty of Veterinary Medicine, where she worked in Production Animal Health and was involved activelly in public health teaching of undergraduate students. She also completed a taught masters in Veterinary Public Health.

In 2012, Ana completed a PhD at the RVC investigating extent and patterns of antimicrobial usage in dogs and cats in the UK. As part of her PhD she also conducted a qualitative study looking at intrinsic and extrinsic factors influencing decision-making by veterinarians when selecting antimicrobial therapy.

After her PhD, Ana worked as a researcher at the RVC in a EFSA tender with the COMISURV consortium developing scenario tree models to assess the role of meat inspection as a surveillance tool for animal health and welfare conditions in pigs and poultry. 

In October 2011, Ana pursued a traineeship at the European Medicines Agency (EMA) with the veterinary unit where she was involved in projects monitoring antimicrobial use and antimicrobial resistance in food-producing and companion animals.

Furthermore, she was a FETP (Field Epidemiology Training Program) fellow with Public Health England; during this period, she was involved in outbreak investigations, disease surveillance and research of infectious and zoonotic diseases in human populations. 

Ana is interested in antimicrobial usage and antimicrobial resistance. She is currently involved in research projects investigating the supply chain and governance of antibiotics in low and middle income countries (LMICs) and in the UK taking a One Health approach. She is also interested in interdisciplinary and participatory research of zoonotic and foodborne diseases.

  • Antimicrobial Resistance (AMR)

    Antimicrobial resistance (AMR) is significant and growing challenge to global health. Existing antimicrobials are becoming less effective and pathogenic organisms are increasing the rate at which they become resistant to treatment. This is a complex problem, with many different factors driving the emergence of AMR at many different levels.

  • Vet Compass Project

    VetCompass is a welfare-focussed epidemiological research project that shares anonymised clinical data from veterinary practices to investigate the frequency and nature of companion animal health problems.

    Modern veterinary medicine has access to increasingly effective tools for diagnosis and treatment; yet many animals still continue to suffer from disorders that might be reduced or avoided if risks were better understood and measured.
