Che Cheng
Psychometrician & Quantitative Psychologist CV
I received my Ph.D. from the Department of Psychology (specializing in developmental psychology & quantitative psychology) and M.Sc. from the Institute of Applied Mathematical Sciences (specializing in mathematical statistics) at National Taiwan University.
My research focuses on the intersection of psychometrics, mathematical statistics, and developmental psychology, developing and applying advanced statistical models to better understand human cognition and behavior.
