I work mainly on the philosophy and ethics of space exploration and policy. I am the author of The Value of Science in Space Exploration (Oxford University Press, 2020), wherein I construct a philosophically-informed account of the value of scientific understanding, and in which I apply this value to several policy discussions, including: planetary protection; space resource exploitation; and space settlement. My approach to these topics draws not only from ethics, but from epistemology, philosophy of science, and social and political philosophy. I am also the editor (with Tony Milligan) of The Ethics of Space Exploration (Springer 2016).
