I have been teaching military history, European history, and the history of empires and imperialism at the National University of Singapore since 1993. I am the Head of the Department of History. I have published extensively in my main area of research interest, the military history of the British Empire. That interest has led me to a broader engagement with the study of imperialism and its influence on Asian and global history, as well as with wider problems of military history in Asia in the 20th century. I have pursued questions in these areas in libraries, archives, research institutes, and especially in the field, in Canada, the USA, the UK, France, Germany, Thailand, Malaysia, Singapore, Indonesia, the Philippines, Cambodia, Vietnam, Hong Kong, Australia, New Zealand, South Korea and Japan. My wider responsibilities include acting as Principal Investigator on the major research project Empire in Asia: A New Global History, and serving as Asia-Pacific Regional Coordinator for the Society for Military History, the largest such professional organization in the world.
