After graduating with a master’s degree in developmental psychology from Beijing Normal University, I have started my PhD project in University of Amsterdam from September, 2018. My main research interests are smartphone addiction and longitudinal study. I will investigate the longitudinal relationships between smartphone addiction and interpersonal relationship, the cognitive biases related to smartphone addiction and the neurobiological mechanisms of smartphone addiction in my PhD thesis. My supervisors are Reinout Wiers, Janna Cousijn, and Helle Larsen.
