I conduct research in Interpersonal Communication. I have research interests in conflict, social networks, and the mathematical modeling of communicative behavior. My primary research deals with interpersonal conflict in general, and bargaining and negotiation in particular. My studies of the bargaining process have appeared in such journals as Behavioral Science, Communication Research, and Communication Yearbook. More recently, I have been studying the dynamics of an infinite-choice, continuous-time Prisoners Dilemma. I teach courses on conflict, social interaction, interpersonal communication, quantitative methods, and judgment and decision making.
