Her most recent book, entitled The World in the Year 1000: When Globalization Began (published in April 2020), explores what happened when the different peoples around the world realized for the first time that they had neighbors and had to decide how to react. Specifically, it examines the people and goods that traveled from one region of the world to another in the five centuries before Columbus. She travels to East Asia frequently, teaching at Yale's joint undergraduate program with Peking University in both 2008-09 and 2011-12, at Yale-NUS in Singapore in fall 2015and at Xiamen University in Fujian, China, in fall 2016.
