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.

Postdoctoral Researchers & Junior Faculty

Oriana Aragón [Website] [CV]

Oriana Aragón is a postdoctoral associate working with John Dovidio, Mark Graham and Margaret Clark studying the integration of women into research and academic fields that in the past have been predominantly occupied by men. This project underpins a larger initiative to bolster diversity in scientific education, research, and careers (NSF, TUES). She studies the impact of summer research programs on women and men's feelings of self-efficacy, mastery of research skills, and intentions to persist onto research careers. In a second line of work, she applies established immigration theory to explain the implicit threat that individuals who are already in research and academic careers may experience when a woman (or minority group member) attempts to enter. Identifying these implicit threats could shape future interventions to convince the majority to open the "border" and allow these minority individuals to enter.

Sarah K. Calabrese [CV]

Sarah K. Calabrese, Ph.D., is an associate research scientist in the Social and Behavioral Sciences Division of the Yale School of Public Health. She earned her Ph.D. in clinical psychology from George Washington University (Washington, DC). Broadly speaking, Sarah's research focuses on racial stereotypes and discrimination in the context of HIV prevention, sexual wellbeing, and mental health. She has particular interest in addressing barriers to the prescription and utilization of HIV pre-exposure prophylaxis (PrEP), with the goal of ensuring equitable access across social lines.

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. Broadly, her research explores how individual differences influence reactions to stressors, psychological wellbeing, unhealthy risk-taking behavior, and belonging in a threatening environment, and uses novel cognitive modification and intervention paradigms to change biases that are detrimental for both individuals personally and others. Specifically, she examines individual differences in the weighting of positives and negatives, and the beneficial consequences of training individuals to give more weight to either positive or negative information. In addition, to diminish negative beliefs directed at women in the sciences she utilizes a novel intervention relying on high quality movies, which teach about and reduce gender bias.

Katie Wang [CV]

Katie Wang, Ph.D., is a postdoctoral fellow in the National Institute of Mental Health HIV Prevention Interdisciplinary Training Program at Yale University's Center for Interdisciplinary Research on AIDS. She is a former doctoral student in the Yale Intergroup Relations Lab (working with John dovidio) and received her Ph.D. in Social Psychology in summer 2014. Broadly speaking, Katie is interested in understanding the experience of stigmatization from the targets' perspective. Her dissertation examines how individual-difference variables, such as stigma consciousness and the utilization of various emotion regulation strategies, interact with contextual factors to shape women's responses to gender discrimination. She is also interested in the unique challenges faced by members of stigmatized groups who are traditionally under-represented in the intergroup relations literature, such as people with disabilities. Working in collaboration with John Pachankis at the Yale School of Public Health, Katie is starting a new program of research examining the role of internalized stigma in shaping the physical and mental health outcomes of sexual minorities and people living with concealable stigmatized identities more generally.

Graduate Students

April Bailey

April Bailey is a first-year doctoral student. She received her BA from Colgate University, majoring in both psychology and women's studies. She is broadly interested in understanding and intervening in gender prejudices and stereotypes. Currently, she is focused on the intersection between gender and nonverbal displays as well as the generic use of masculine images to represent everyone, regardless of gender.

Sara Burke [Website] [CV]

Sara Burke is a PhD candidate in social psychology working with Jack Dovidio and Marianne LaFrance. 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, biracial people, and other groups perceived to fall in between more recognized social groups.

Kevin Callender

Kevin is a fifth-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.

Ava Casados

Ava Casados is a second-year clinical psychology student. Her research is aimed at addressing disparities in mental health service use among adolescents and ethnic minority individuals. She is particularly interested in mental illness stigma and the relationship between culture and mental health conceptualizations. Prior to coming to Yale, she received her B.A. in Psychology and Fine Arts from the University of Southern California.

Katie Duchscherer

Katie Duchscherer is a second-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 processes behind stereotyping and stereotype maintenance. She is currently researching how individual differences affect stereotype maintenance, as well as investigating popular lay justifications for making use of stereotypes.

Suzanne Horwitz [Website]

Suzanne Horwitz is a 6th 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 5th year doctoral student. She received her B.S. in psychology and political science from Union College. Broadly, she is interested in the situational and motivational factors that shape political ideology and other belief systems. Her current research examines how subtle shifts in mindset level (abstract vs. concrete thinking) can have important downstream consequences on political attitudes, moral values, and prejudice.

Katie Oltman [CV]

Katie Oltman is a second-year student, before coming to Yale she received B.A.s in Psychology and English from the University of Nebraska-Lincoln. Katie is primarily interested in the underlying assumptions individuals use to identify social groups, and the downstream consequences of these processes, such as stereotyping and discrimination. Specifically, Katie is interested in "entitativity," the process where a collection of individuals comes to be identified as a single group. Her current work focuses on exploring which factors of a social environment predict entitativity, and how we can manipulate perceptions of entitativity to induce positive group attitudes.

Gina Roussos [CV]

Gina Roussos is a second-year graduate student. She recently graduated from the University of Pittsburgh with her B.A in Psychology, with minors in Applied Statistics and Italian Studies. She is interested in how individuals' prejudices and stereotypes develop and evolve. She is particularly interested in how to change attitudes and stereotypes about social groups. Within this area of prejudice intervention, she examines how different forms of television, film, print media, and gaming platforms can influence perceptions about others.

Lauren K. Ruth [CV]

Lauren is a doctoral candidate in Social Psychology. She received her B.S. in Psychology and B.A. in Philosophy from Tulane University in New Orleans. Prior to starting graduate school, she taught high school math. She is broadly interested in the processes that create how we observe gender in others and in ourselves. Her dissertation work examines how interdependence between low-status and high-status groups impacts how the high-status group stereotypes the low-status group.

A. Nicholas Santascoy

Nicholas Santascoy is a fourth-year doctoral student. He received his BA in psychology from the University of California at Berkeley. His research emphasizes the catalyzing effect of social cognition (stable beliefs and transient appraisals) on the social psychology of bias. For example, in one line of work, he examines how lay causal beliefs of stereotyping impact people's total psychological response (cognitive, conative, affective, and behavioral) to their own and others' bias.

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

Fabian is a second-year doctoral student. His primary research focuses around the psychological processes that impede or facilitate action for social change, which he studies in a variety of cultural and intergroup contexts. His current research examines why and when positive relations with high-status groups undermine efforts for social change, and under what conditions members of advantaged groups develop solidarity with the disadvantaged. Prior to coming to Yale, Fabian received a M.Sc. from the University of Oxford, and a B.Sc. from the University of Groningen.

Roseanna Sommers

Roseanna Sommers is in her third year of her dual degree program in psychology and law. Her research uses insights from psychology to critique theories of human cognition and behavior embedded in legal doctrines. Before coming to Yale, Roseanna served as a fellow in the Department of Bioethics at the National Institutes of Health (NIH). She holds a BA in psychology from Swarthmore College.

Elizabeth Tepe

Liz is a third-year doctoral student in the clinical psychology program, primarily advised by Jack Dovidio. 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 [Website] [CV]

Andrea Vial is a third-year doctoral student. She received her BA in psychology with a minor in sociology from Hunter College of the City University of New York. Her research focuses broadly on leveraging experimental methodologies to investigate how gender stereotypes and prejudice impact the lives of women. Most of her work has centered on how people react to feelings of power and powerlessness, revealing that high-power positions sometimes have different social identity implications for men and women.
