We are delighted to welcome Dr Chang Xu as a lecturer in Developmental Psychology.

Chang obtained all three of her degrees at Carleton University in Ottawa, Canada, earning:

• BA Psychology and Mass Communication (2008)
• MA Developmental Psychology (2013)
• Ph.D. in Developmental Psychology (2018)

After graduation with her Ph.D. Chang continued her research at Carleton University as a postdoctoral research fellow, before being appointed to her position at Queen's in September 2022.

Chang is interested in cognitive developmental psychology, with a focus on children's mathematical skills and related cognitive processes.  In particular, she focuses on understanding the developmental course of number integration, that is, the process of making connections between number concepts and symbols, which is central to children’s construction of higher-level mathematical understanding. She is also interested in investigating the development of mathematical skills for children who are learning mathematics in a second language, as well as developing accessible mathematical interventions aimed at improving cognitive and educational outcomes for children.
