I am associate professor and the William and Jeanie Barton Chair at the Norman Paterson School of International Affairs, Carleton University in Ottawa, Canada. My research focuses on Canadian defence policy and politics, civil-military relations, executive-legislative relations, and international policy-making in the Westminster tradition.

In May 2015, I was appointed a member of the Independent Review Panel for Defence Acquisition (IRPDA). The position is non-partisan and legally within the civil service, yet it is outside of the regular organizational structure of the Department of National Defence and Canadian Armed Forces. The appointment has a three year term, but is held at the pleasure of the Governor-in-Council.
