Dr Matthew Cole is a Lecturer in Sociology at the Open University. His research focuses on how we learn to conceptually separate other animals into categories, such as 'friends' or 'food', and how these categories serve the interests of industries which profit from animal exploitation. From these concerns, Matthew also researches the role of veganism as an alternative to animal exploitation.
