Research Interests

My research investigates social comparison processes and how upward versus downward comparisons affect people’s motivation and emotions. Beyond that, I examine how different states or dispositional traits influence people’s perception of their social environment and their selection of comparison standards. In another line of research, I study the interpersonal functions of humor and how people use humor to socially connect (e.g. affiliative humor, fun) or to keep others at distance (e.g. sarcasm, teasing).
