Current Research

I am an Ernest May Fellow at the Kennedy School of Government, Harvard University, where my research explores intelligence history, grand strategy, and international relations.

I am currently writing a book about the rise and fall of intelligence superpowers, from the twentieth century’s World Wars to cyber warfare today. This research builds on my PhD in History at Trinity College, Cambridge, and postdoctoral Junior Research Fellowship at Darwin College Cambridge, where I wrote my first book, Empire of Secrets. British intelligence, the Cold War and the Twilight of Empire (Harper-Press 2013). Highly acclaimed and translated into multiple languages, it won the Longman History-Today Book of the Year Award 2013.

While at Cambridge, I was also a lead researcher on Christopher Andrew’s unprecedented authorized centenary history of the British Security Service (MI5), Defend the Realm (Penguin 2009). This research position provided me, for six years, with privileged access to archives of MI5, the world’s longest-running security intelligence service. I am a regular contributor, among other publications, to the Times Literary Supplement and Prospect Magazine, and my research has featured on BBC radio and television, and in Politico, among other broadcast and print media. I am also a qualified English barrister (attorney) and have worked on several high-profile litigation cases involving defence and security matters and major international regulatory investigations.
