Dr Mary Friel


I joined the University of Leeds as a postdoctoral researcher on the PigSustain in March 2017.  I am working with the pig industry to collect and analyse data on pig production, health and welfare. I am also contributing to the development a systems model of the UK pig industry to assess its resilience.

I completed my PhD on welfare indicators in pigs at Queen's University Belfast in 2017.  

Research interests

My research is focused on farm animal health and welfare, sustainable agriculture and systems modelling. I have a background in applied animal welfare research, developing practical indicators of animal welfare and designing interventions to improve animal health and welfare on farm. I am currently conducting epidemiological analysis on large scale pig health and production datasets from the UK to inform a systems model of the UK pig industry on the PigSustain project.
