Academic Biography:

I earned a B.A. in psychology from Eastern Washington University in 1999, a M.S. in clinical psychology from Florida State University in 2001, and a Ph.D. in social psychology from Florida State University in 2006. I have been a faculty member in the Department of Psychology at ETSU since August 2006, where I direct the Self & Relationships Lab.

Research Interests:

Broadly, I am interested in the interaction between the self, individual difference factors, and social factors on mental and physical health. My primary research examines factors that impact self-regulatory resources and self-control, such as social anxiety. I also conduct research examining rejection sensitivity, predictors of online dating, the teaching of psychology, and research methodology in social psychology.
