Research Interests

My main research interests are in developing and disseminating innovative psychometric and statistical methods for addressing issues related to well-being and cognitive development. I have explored how we can apply causal models, including propensity score matching and mediation models, to psychometric and psychological research. I am also researching quantitative methods for analyzing response processes, longitudinal and multilevel data, and complex data, e.g., mixture distributions and zero-inflated distributions.

To analyze large scale assessment and text data, I have recently integrated machine learning and natural language processing (NLP) into my research. I also have been combining assessment and eye-tracking techniques into my studies on cognitive processes.
