Research Interests:

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. As an applied psychologist, 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. 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.

As an applied psychologist, another question that drives my research is: how can we accurately quantify constructs of interest in individuals, organizations, and societies? This entails research on newer measurement models that are integrated with latent class and multilevel techniques. With latent class modeling, we can identify groups of individuals that have unique signature patterns (e.g., signature strengths); with multilevel models, key characteristics of collective units (e.g., organizations and societies) can be measured more effectively. At a more basic level, I seek to advance current measurement models that impact construct validation techniques.

My hope is to contribute to the advancement of individual, organizational, and societal well-being, through well-being research, and to enhance scientific rigor through methodology.
