Tom Simpson is Associate Professor of Philosophy and Public Policy at the Blavatnik School of Government, University of Oxford, and a Senior Research Fellow at Wadham College

He works particularly on trust, and issues at the intersection of technology and security. For an overview of his research, see this broadcast with ABC.

He joined the School from Cambridge, where he was a Research Fellow at Sidney Sussex College, and was also educated (BA, MPhil, PhD).

Between degrees he was an officer with the Royal Marines Commandos for 5 years. He served in Northern Ireland; Baghdad, Iraq; and Helmand Province, Afghanistan. The academic life is undoubtedly a privilege, but he remains conflicted about its sedentary nature.
