I'm a mathematician at the University of Leeds. My research focuses on how humans and animals use information and how we make decisions both individually and collectively. I have a particular interest in collective intelligence and diversity: how do many different individuals come together to create a more intelligent group? What role do incentives an​d group composition play in maximising group performance? What are the difficulties of collective coordination and how can they be overcome? 

I'm also interested in a variety of topics concerned with data analysis, particularly in areas of selection effects and other observational biases. How do we use data to form new knowledge, and how might data mislead us? My statistics research covers areas such as navigation, surgery, criminology, pedagogy and palaeontology.
