Research Interests

My research investigates the intersection of two broad domains of social psychology: 1) group processes and intergroup relations, and 2) attitudes and persuasion. Within these domains I investigate how social groups influence people's self-conception, attitudes, physiology, and biology as they relate to health behaviors. The goal of my research is to integrate basic cognitive processes into social interactive processes, societal processes, individual process, and internal processes that explain individual health behavior.

Research in my lab has a broad foci on: 1) the role that group processes and intergroup relations play in risk taking, attitude change, and persuasion; 2) the motivational role played by self-uncertainty in attitude change, group behavior, intergroup relations, and self-conception 3) influence processes within and between groups; 4) the structure of self-conception and identity in group and intergroup contexts; and 5) on physiological and biological processes related to attitude change and group processes.
