I am a psychometrician with an established reputation and extensive industry experience, now focusing on modelling response processes to non-cognitive assessments (personality, motivation, attitude etc.) using multidimensional item response theory (MIRT).
Specifically, I am interested in modelling preference data (such as ranking and paired comparisons tasks, and forced-choice questionnaires), modelling response processes contributing to common biases and impression management, and test optimisation and computerised adaptive testing (CAT).
