Department of History and Philosophy of Science


Hatton Lecturer in the Philosophy of Public Health

I am a Senior Lecturer, with research and teaching interests in a variety of topics at the intersection of philosophy of science, applied ethics, social epistemology, and political philosophy.

My main research to date has clustered around a series of concepts which raise both ethical and epistemological challenges: certainty, communication, chance and categorisation. I am particularly interested in how these concepts are used in policy-making, and have explored case studies ranging from Lysenkoist genetics to the Intergovernmental Panel on Climate Change to contemporary alcohol policy. In my current research, I am particularly interested in debates over the early detection and prevention of cancer. For some initial thoughts on this topic, please see here.

From 2015 to 2018, I co-directed with Anna Alexandrova a project on the 'Limits of the Numerical' at CRASSH. I am also affiliated with the Leverhulme Centre for the Future of Intelligence, with Cambridge University's Public Health Strategic Research Network, and with the Early Detection Programme at the Cambridge Cancer Centre.
