About the Lab

We study goals, motivation, well-being, priming, personality, materialism, and values (and that's just the short list!).  Currently I have two Ph.D. students, Ryan Goffredi and Erica Holberg.  It is late in my career, and I will not be accepting new students.

Research Interests

I primarily study goals, motivation, and psychological well-being. I am active in the "positive psychology" movement. Research questions include, "is it possible for people to become happier, and if so, how?" "Why do people pursue overly materialistic goals, and how can they be helped to select more satisfying goals?" "What is the nature of optimal motivation and optimal functioning?"
