My research is largely interdisciplinary, spanning political sociology, political psychology, and law & society. I am a specialist in the area of transitional (historical) justice but I also study collective memory, democratization, corruption, forgiveness and revenge. I am the author of Lustration and Transitional Justice (University of Pennsylvania Press, 2011), which conceptualizes exclusive, inclusive and reconciliatory personnel systems and which received the Concept Analysis Award by the International Political Science Association in 2012. I have recently published a monograph entitled Communists and Their Victims (University of Pennsylvania Press, 2018), which uses surveys, survey experiments and qualitative methods to examine the impact of justice on victims, perpetrators and society; and which results in the transformative theory of justice. I have completed a co-authored monograph (with Ian Holliday) entitled Liberalism and Democracy in Myanmar (Oxford University Press, 2018) and proposed the concept of limited liberalism to explain various puzzles of political culture in democratizing countries. My major articles appeared in the American Journal of Sociology, Political Psychology, Journal of Conflict Resolution, and other indexed journals. I am a recipient of grants from the British Academy, United States Institute of Peace, the South African National Research Foundation, and GRF Hong Kong. Before coming to Lingnan, I held positions at various universities, including Newcastle (reader), Yale (post-doc), CityU (research), BaptistU (visiting), Wits (post-doc), Oxford (visiting), Harvard (visiting) and Masaryk (lecturer).
