Dr Leach is interested in how intraindividual processes (e.g., motivation, cognition) shape social (e.g., self-knowledge) and affective (e.g., happiness) outcomes. For example, his doctoral research investigated differences in how powerful and powerless people experience and express positive and negative affect. Currently, Dr Leach is interested in the possibility that people may strategically forget information that is incongruent with their behaviour or world-view, and how such processes may shape human-animal relations (e.g., beliefs regarding animal sentience).
