As an I-O psychologist embedded within the broader field of psychology, my goal is to programmatically pursue cross-disciplinary lines of inquiry in methodology (i.e., measurement, continuum specification, latent class modeling, Big Data / data science) and well-being (i.e., societal well-being, wellness programs, work – leisure [e.g., arts/humanities activities] interface). I have co-edited the following books: Big Data in Psychological ResearchHandbook of Well-BeingHandbook of Positive Psychology Assessment, The Oxford Handbook of the Positive Humanities, and Technology and Measurement around the Globe.

My Purdue research team consists of graduate students Victoria Scotney (2019), Daphne Hou (2020), Fanyi Zhang (2021), and Gloria Liou (2023). My current active collaborators include Munmun De ChoudhurySidney D’MelloAngela DuckworthJames PawelskiLyle Ungar, & Sang Woo. Feel free to contact me if you are interested in collaborating on research projects.

My greatest joy comes from mentoring students and post-docs.
