As a social psychologist, my areas of research interest have to do with emotions and how they shape the way we look at our past and anticipate the future. Specifically, I am interested in the fading affect bias and affective forecasting error. The fading affect bias suggests negative affect associated with negative memories fades away faster than the positive affect associated with good memories. Affective forecasting refers to our tendency to overestimate the duration and magnitude of our emotional reactions to future life events, both positive and negative. Both theories are somewhat counter intuitive and suggest that our minds our constantly and non-consciously working to keep us happy and motivated to work toward goals that we think will make us happy.

Both of these research areas fall under the broad banner of Positive Psychology, one of the classes I teach at Gannon. I also teach Social Psychology, Industrial/Organizational Psychology, and will Motivation and Emotion. I also teach Psychological Statistics frequently and have published and presented research related to best methods for the teaching of statistics and maintain my blog,, to share my ideas about making statistics entertaining (yes, it can be done).
