Assistant Professor of Psychology (Quantitative Methods)

University of Southern California


I am an Assistant Professor of Psychology (Quantitative Methods) in the Department of Psychology at the University of Southern California. I am from Macau and speaks Cantonese as my native language. Mathematics has always been a favorite subject to me, but my growing interest in understanding the human mind lead me to pursue a bachelor degree in Psychology at the University of Macau, where I discovered that a career of developing and applying quantitative methods in the social sciences would be a very good fit to me.

I am interested in all kinds of statistical methods, but currently my research areas include multilevel modeling, structural equation modeling, effect size statistics, and measurement invariance. I also have collaborations on projects studying the prevalence, antecedents and consequences of gambling disorder, and in other areas such as evolutionary psychology, social psychology, developmental sciences, health sciences, etc.
