Research Interests:

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). My goal is to contribute more broadly beyond I-O psychology to enhance measurement/methodology research for psychology and develop science-based well-being programs/policies at organizational and societal levels.

       Well-Being. How do we conceptualize well-being and how can we improve the well-being of societies, organizations, and individuals? This question is of increasing concern to academics from many fields and policy makers. I seek to delineate the social, economic, and political determinants of well-being at both the micro- and macro-level with an eye toward public policy. I am interested in both modern conceptions of well-being and classical notions of well-being such as character and interests. Much of my research is currently based on psychological theories that I am seeking to integrate with other fields such as business, economics, and sociology.

       Methodology. Another question that drives my research is: how can we accurately quantify constructs of interest in individuals, organizations, and societies? At a more basic level, I seek to advance measurement of key psychological domains (e.g., taxonomies of character, psychological situations, and vocational interests) and also measurement models that impact construct validation techniques. I am also interested in Big Data / data science approaches. To this end, I have also developed software platforms for new modes of data collection through mobile technology (www.expimetrics.com) used by over 1,200 academics around the world.
