Dr. Christopher Hitchcock's research is focused on causation. He explores the kinds of causal reasoning used in the sciences, law, and everyday life, examining how causal questions in science differ from those that arise in moral or legal domains. His research makes use of formal tools for causal modeling that have been developed by philosophers, computer scientists, statisticians, and epidemiologists. In addition to causation, Hitchcock has done work in a number of other areas of the philosophy of science, including the philosophy of biology and the confirmation of hypotheses by evidence. He also works in formal epistemology, which employs mathematical tools such as probability to represent belief, inference, and evidence. He has recently undertaken a collaborative project in formal epistemology that involves modeling agreement and disagreement between individuals.
