Principal Investigator

John F. Dovidio [Website] [CV]

My work centers around issues of social power and social relations, both between groups and between individuals. I explore both conscious (explicit) and unconscious (implicit) influences on how people think about, feel about, and behave toward others based on group membership. I continue to conduct research on aversive racism, a contemporary subtle form of prejudice, and on techniques for reducing conscious and unconscious biases.

Sylvia P. Perry [Website] [CV]

Sylvia Perry is a Postdoctoral Associate working primarily with John Dovidio (in the Yale Intergroup Relations Lab) and Michelle van Ryn (in the University of Minnesota's Department of Family Medicine and Community Health). She received her Ph.D. in social psychology from the University of Illinois at Chicago in the Fall of 2010. Her research, broadly speaking, focuses on issues related to intergroup bias, bias reduction, and intergroup interactions. With her current work, Sylvia is exploring: (a) how people respond to accusations of bias, and the importance of people's pre-existing awareness of their biases (or bias awareness) in these contexts; (b) bias awareness in children, and the development of bias awareness over time; and (c) the various situational and individual factors that contribute to healthcare disparities.

Evava S. Pietri [CV]

Eva Pietri is a postdoctoral associate working in Jack Dovidio's Yale Intergroup Relations lab, and at the Yale Center for Scientific Teaching. After completing her undergraduate work at Amherst College, she received her Ph.D. in psychology at Ohio State University, working under the supervision of Russell Fazio. Her work explores two types interventions, both of which are aimed at correcting negative biases. The first intervention is a cognitive modification paradigm that recalibrates individuals not to overweight negative information. The second explores the use of entertaining movies to change the negative bias against women pursuing careers in the science, technology, engineering and math (STEM).

Graduate Students

Sara Burke [Website]

Sara Burke is a third-year doctoral student. She received her BA in psychology and English with a minor in statistics from the University of Michigan. Her research explores variations in the way prejudice operates when it targets different groups, and one of her central goals is expanding the body of information about intergroup bias to better account for underexamined targets of prejudice. In one line of work, for example, she examines attitudes toward bisexual people and other groups perceived to fall between more recognized social groups.

Kevin Callender

Kevin is a fourth-year doctoral student. He received his BA in psychology, with minors in applied statistics and moral philosophy from the University of Michigan. He is primarily interested in understanding bias against sexual minorities -- especially within the workplace context. His dissertation investigates how uncertainty about whether or not someone has a concealable stigma shapes the thoughts, feelings, and behaviors directed at 'ambiguous' individuals. Outside the realm of academia, Kevin is interested in management consulting, marketing strategy, and statistical modeling.

Katie Duchscherer

Katie Duchscherer is a first-year PhD student. Before beginning her studies at the Intergroup Lab, she received her BA in psychology from Stanford University. In general, Katie is interested in the causes of and processes behind prejudice and stereotyping. She is currently working on projects involving how personality factors affect the maintenance of stereotypes, as well as the use of perspective-taking games in decreasing prejudice and increasing cross-group empathy.

Suzanne Horwitz [Website]

Suzanne Horwitz is a 5th year doctoral student. Prior to joining the Intergroup Relations Lab, she received her BS in psychology from Tufts University, worked at the Rochester Baby Lab under Richard Aslin, and was a student in the developmental psychology program at Yale. She is broadly interested in how social group attitudes form and how these attitudes lead to biased behavior, specifically focusing on the domain of social class as test case for understanding these processes. Suzanne's current work examines on the role of implicit wealth attitudes in regulating favoritism/discrimination toward individuals with different social class backgrounds.

Jamie Luguri [Website] [CV]

Jamie Luguri is a 4th year doctoral student. She received her B.S. in psychology and political science from Union College.

Fabian M. H. Schellhaas [Website] [CV]

Fabian is a first-year doctoral student. His work revolves around the intersection between prejudice reduction and collective action, with a focus on the psychology of stability vs. change in intergroup hierarchies. Some of his work investigates why and when positive relations with high-status groups undermine efforts for social change among the oppressed, and whether the adoption of more inclusive identities can promote political solidarity among the advantaged. Prior to coming to Yale, Fabian received a MSc in Psychological Research from the University of Oxford, and a BSc in Psychology from the University of Groningen.

Jacqueline S. Smith [CV]

Jacqueline S. Smith is a PhD candidate in Social Psychology working with Marianne LaFrance and Jack Dovidio. She is broadly interested in how people perceive and respond to emotions expressed by others. One line of research focuses on how emotion stereotypes influence expectations for the emotions of people belonging to multiple social categories. Her dissertation explores the consequences of gender and intergroup biases in judgments of emotional appropriateness. She also examines how people respond to anger expressed by relationship partners (with Margaret Clark) and how gender and emotion stereotypes influence the well-being and success of male and female leaders (with Victoria Brescoll).

Roseanna Sommers

Roseanna Sommers is a first year doctoral student. Her interests lie at the intersection of law and psychology, and she is pursing a J.D. at Yale Law School concurrently with her psychology studies.

Before coming to Yale, Liz received her B.A. in Psychology and Political Science from Amherst College. Her research focuses on how implicit beliefs about emotion, specifically whether emotion is malleable or fixed, influence how individuals regulate their emotions in the moment. She has also examined how subtly manipulating these implicit emotion beliefs then influences the strategies individuals use to regulate their negative emotions, and ultimately how successful they are in these efforts. She is also interested in how these emotion beliefs operate within the context of psychiatric disorders that are characterized by emotion dysregulation, such as depression and generalized anxiety disorder. She has also collaborated with Susan Nolen-Hoeksema and June Gruber.

Andrea Vial

Andrea Vial is a second-year doctoral student primarily advised by Jaime Napier. She received her BA in psychology with a minor in sociology from Hunter College of the City University of New York.
