I have 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 problems in public health policy and climate science: chance, certainty, categorisation and causation.
My current research centres around two interlocking topics. First, I am interested in how recent work on "value-laden science" might affect familiar normative questions about the proper relationship between experts, publics and policymakers. Second, I am engaged in a comparative study of the ethical and epistemological challenges in two key areas of public health policy, vaccination and cancer screening.
I am also affiliated with Cambridge University's Public Health Strategic Research Network, and with the Early Detection Programme at the Cambridge Cancer Centre, and serve on the National Statistician's Data Ethics Committee for the Office of National Statistics.
