In spring 2017, I was appointed as a Changjiang Scholar (长江学者) at Central China Normal University (华中师范大学) with the title of Visiting Professor of Early Modern and Contemporary Chinese History (中国近现代史 讲座教授), 2016-2019. Appointment as a Changjiang Scholar is the highest academic honor conferred on individual scholars by the PRC Ministry of Education. Only a limited number of overseas scholars are recognized every year, especially in the humanities and social sciences. In connection with this appointment, I will work with Central China Normal University to advance training and research in quantitative history, with an emphasis on the construction and analysis of big social science datasets. My primary appointment remains at the Hong Kong University of Science and Technology, where I am Professor of Social Science since 2013 and Associate Dean for the School of Humanities and Social Science.
