Department of Zoology



I have a BA(Hons) in Preclinical Veterinary Medicine, from the University of Cambridge, and I have now started a BBSRC-funded DTP program in agriculture and food security.

As an undergraduate I carried out a research project in the department of Zoology, and since graduating I have worked for:

- the Food Climate Research Network (FCRN) working on research and communications;

- the University of Cambridge Conservation Science Group investigating sustainable grazing; and

- the Commonwealth Scientific and Industrial Research Organisation (CSIRO) in the Global Food and Nutrition Security team researching climate-friendly red meat.


Food production has more impact on land use, biodiversity and greenhouse gas (GHG) emissions than any other human activity. In particular, rapidly rising demand for animal products is widely considered to be unsustainable, leading to calls for “sustainable intensification”.

Livestock intensification has increased production and profits (e.g. via temperature- and pathogen-controlled environments requiring less labour and land), but many worry that such high-intensity techniques bring with them other important environmental and health costs.

I am interested in investigating the limits of livestock intensification, including the trade-offs between intensification and animal welfare, antimicrobial use, and environmental externalities.
