I am a professor at the Norman Paterson School of International Affairs. My past research has focused on Canadian defence policy and procurement, Canadian defence governance and civil-military relations, and Canada-United States defence relations. My current research examines executive power and legislative-executive relations in Westminster states, with a particular focus on foreign and defence affairs. In addition, I have an on going research interest in the Crown, Parliament, and their relationship in the Canadian constitution. I am also a Senior Associate Fellow with the Royal United Services Institute and a Fellow with the Canadian Global Affairs Institute.

In addition to my academic work, I served as a member of the Independent Review Panel for Defence Acquisition (2015-2022) and as a member of the Independent Review Panel of the evaluation of options to replace Canada’s CF-18 fighter aircraft (2012-0214). I have also served as a consultant for government and the private sector.

I write two Substacks:

Debating Canadian Defence (commentary on Canadian defence affairs)

In Defence of Westminster (commentary on political constitutional issues)
