Research Interests:

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 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.

Another question that drives my research is: How can we 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 Journal of Applied Psychology, Personnel Psychology, Organizational Research Methods, Applied Psychological Measurement, and Educational and Psychological Measurement.

My research has been featured in various media outlets such as Wall Street Journal, APA Monitor on Psychology, Scientific American Mind, Psychology Today, MSNBC. A sample of my funded grants and representative publications is shown below.

Research Team

My research team consists of my graduate students Lauren Kuykendall, Vincent Ng, and Cassie Batz (incoming - Fall 2014), collaborators at Purdue, and other universities. Lauren, Vincent, Cassie and I currently are undertaking multiple writing and research projects on well-being. I also work closely with collaborators from different fields as I enjoy multidisciplinary research. Feel free to contact me if you are interested in collaborating on research projects.

Potential Graduate Students

I do not have funding for graduate students for Fall 2015 and am not intending to admit any students. However, potential students with independent funding are welcome to apply.
