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. My research on well-being has appeared in journals such as Psychological Bulletin, Journal of Personality and Social Psychology, Psychological Science, Social Psychological and Personality Science, Journal of Happiness Studies, Social Indicators Research, and Journal of Vocational Behavior.

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 research on methodology and various methodological contributions have appeared in journals such as Psychological Bulletin, Perspectives on Psychological Science, Journal of Applied Psychology, Personnel Psychology, Organizational Research Methods, Applied Psychological Measurement, and Educational and Psychological Measurement.

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.

Research Team

My primary research team consists of my graduate students Vincent Ng (2013) and Cassie Batz (2014), my post-doctoral research Chris Wiese and collaborators at Purdue. In addition, I work with graduate students in the statistics department on methodological projects.

Vincent, Cassie, Chris, and I currently are undertaking multiple writing and research projects on well-being. Qiming, Yaowu, and I are working on different methodological projects. I also work closely with collaborators outside and within Purdue. Some of my current active collaborators include: James Pawelski, Angela DuckworthEd DienerJames LebretonSang Woo, and Rong Su. Feel free to contact me if you are interested in collaborating on research projects.
