Justin Clarke-Doane joined the Columbia department in 2014. His work centers on metaphysical and epistemological problems surrounding apparently a priori domains, such as morality, modality, mathematics, and logic. He is particularly interested in similarities and differences between the areas. His aim is to understand the place of apparently a priori inquiry in our intellectual and practical lives. He is an Honorary Research Fellow at the University of Birmingham, UK, an Honorary Research Associate at Monash University, Australia, and has been Visiting Scholar at the Institute for the History and Philosophy of Science and Technology (IHPST), Université Paris 1 Panthéon-Sorbonne. The Philosopher's Annual selected his papers as among the "ten best in philosophy" in 2012 and 2014.
