I am a Lecturer in Work Psychology. Before joining the Management School in 2019, I was an Assistant Professor in Psychology at the Education University of Hong Kong.
I completed my PhD at Lancaster University, UK and my postdoctoral training at Carnegie Mellon University, US. My program of research focuses on identifying the cognitive factors that influence individual and group problem solving, particularly for problems requiring creativity and innovation. I also examine how solutions to these problems can be facilitated through the use of different approaches, e.g., incubation, sleep, and task-switching.
My primary research focuses on examining cognitive processes underlying creative problem solving, and identifying ways to manipulate these processes to facilitate creative thinking at both individual and group levels.
I am interested in supervising students in the following areas:
Creative problem solving
Interruptions (e.g., breaks/ task-switching) and Problem Solving Performance
