POSTDOCTORAL FELLOWS

Yerin Park
Yerin is a Canady Diversity Science Fellow at the Department of Psychology at Northwestern University. She earned her B.A. in Psychology and Business from Korea University and M.A. and Ph.D. in Child Study and Human Development from Tufts University.
Yerin is interested in disparities in adolescents’ opportunities for personal identity development. Her current work focuses on how stereotypes against minoritized social groups (e.g., youth of color, immigrants, lower class) challenge the identity exploration processes of young people. Ultimately, Yerin aims to produce research that informs policies and practices to help all youth thrive through supporting healthy identities that are flexible and align with their individual strengths and potential.
Yerin is originally from Seoul, South Korea. In her free time, Yerin likes taking long walks to explore the city and listening to music (especially live!).

Demond M. Hill
Demond M. Hill, Ph.D., is a Postdoctoral Scholar in the Department of Comparative Human Development at the University of Chicago. He holds a B.A. in Education from Edgewood College, an M.A. in Educational Policy Studies from the University of Wisconsin, Madison, and a Ph.D. in Social Welfare from the University of California, Berkeley. As a community-oriented interdisciplinary and applied scholar, Demond’s research lies at the intersection of emotion science, education, racial inequality, and well-being. Broadly, his work centers on the everyday social function of emotions—such as love, compassion, joy, rage, and shame—and how these emotions provide insight into the mental and emotional well-being of Black students. His research investigates how racialized and sociocultural contexts shape Black students’ emotional development, including their understanding, expression, and regulation of emotions. He also examines how various factors and processes within schools either promote or disrupt the human flourishing of Black students. His research is grounded in three primary areas:
1. Everydayness of Emotions: How emotions are deeply embedded in racialized and sociocultural contexts, how these emotions shape social interactions and, in turn, how these interactions affect the emotional and mental well-being of Black students.
2. Schools as Sites of Human Flourishing & Belonging/ness: How schools can serve as environments that support human flourishing and belonging, focusing on the mental and emotional climates shaped by the everyday emotional lives of students and teachers. By studying the everyday emotional interactions within schools—through objects, spaces, language, memory, culture, and relationships—he seeks to understand how these environments can be reimagined as spaces of belonging, healing, and holistic wellness.
3. Power of Play & Spaces for Play: How play and playfulness, as a transformative therapeutic and healing practice, can foster social and emotional well-being and promote a more diverse, healing oriented, and liberatory community with schools.
As a former educator and mental health professional, Demond is deeply committed to working alongside communities to co-create holistic, humanizing, and culturally relevant interventions that promote human flourishing and belonging. His efforts are focused on building therapeutic environments and public spaces that nurture the emotional and mental health of marginalized students, advancing a vision of greater communities as spaces of collective liberation and wellness.
GRADUATE STUDENTS

Courtney Jones
Courtney is a PhD candidate advised by Dr. Onnie Rogers. Her research primarily focuses on racial-ethnic identity development in people with multiracial backgrounds. Through her research, she hopes to better understand how and why some multiracial individuals may develop a multiracial or a monoracial identity, considering the roles of family, peers, and broader society. She is also interested in unpacking what having a multiracial background during times of heightened racial tension means for individuals’ perceptions of their role in racial justice activism. Some of Courtney’s previous work has looked at how multiracial children talk about the racial identity-targeted messages that they receive from others, and to what extent those messages change over time. When she’s not working on her research, Courtney likes to hike, attempt new yarn crafts, and bake vegan goodies!

Brandon Dull
Brandon is a third-year Comparative Human Development Ph.D. student in the DICE lab. Broadly, his research focuses on using critical theories and perspectives to examine how ideologies of white supremacy manifest in human development, education, and identity. Currently, he is using qualitative and participatory methods to explore the possibilities and limits of schools in challenging whiteness and white identity. Outside of research, Brandon enjoys spending time with his partner and dog, going for runs, and trying new vegan restaurants.

Amanda-Joy Wright
Amanda-Joy Wright is a second-year Comparative Human Development student. Her research investigates the mental health, well-being, and identity development of Black women and girls, with an emphasis on how systemic inequities and social contexts shape their lived experiences. Through qualitative methodologies and community-centered approaches, she examines the impact of race- and gender-based oppression on identity formation and mental health, particularly within school and community contexts. Through her work, she hopes to advocate for a more nuanced and contextually informed understanding of Black women and girls to drive the development and reimagination of equitable policies and practices. Prior to starting her Ph.D., Amanda earned a B.A. in Psychology and an M.A. in Developmental Psychology from Cornell University. In Amanda’s free time, she enjoys traveling, cooking, photography, and live jazz music.

Vanessa Cordova
Vanessa Cordova Lopez is a first-year Comparative Human Development Ph.D. student in the DICE lab. Originally from Valparaiso, Chile, Vanessa completed her BA in Music Education at the University of Playa Ancha (Chile) and worked as an educator in both public and private schools. Vanessa migrated to the United States in 2018, and inspired by her lived experiences as an immigrant, decided to pursue a career in psychology. Through her research Vanessa seeks to investigate the processes and factors that inform how immigrant youth racialized as Latinx in the U.S. (re)form their identities, navigate their social positions, and negotiate– and resist– oppressive ideologies and social structures across national borders. In her free time, Vanessa enjoys playing music, hiking, traveling, and discovering new brunch spots!

Ana Vasan
Ana is a fourth-year PhD candidate in the Department of Comparative Human Development. Her current research focuses on political action taken in schools by educators with non-dominant identities. In particular, she is interested in the possibilities of liberatory education as conceived by Black and queer educators who work in school spaces mired by logics of oppression and hegemony. Through her research, she hopes to locate the relationships between individual healing, interpersonal coalition, and system-wide transformation of educational organizations. In previous work, Ana has explored the creation and implementation of policies related to safety, restorative justice, and antiracism in schools.

Kenya Tuttle
Kenya Tuttle is a fifth-year doctoral student at Garrett Evangelical Theological Seminary in the area of Pastoral Theology, Personality and Culture. She is currently completing a 3rd year clinical fellowship at the Center for Religion and Psychotherapy of Chicago. Her research interest centers Black girls’ interpersonal relationships and attachment styles and ask how Black girls are affected by intergenerational trauma. Prior to starting the PhD, Kenya taught middle school English and Social Studies for five years to Black and Hispanic girls, where she was also a girls’ basketball Coach and Audubon Conservation Leader. Before teaching, she was a Theological Editor for youth Sunday school materials for a Baptist denominational publishing house.

Juan Eduardo Garcia-Cardenas
Juan, a PhD student at Northwestern, is originally from Vallejo, California. He earned his B.A. in psychology at UC Davis in 2021 and worked in both research and clinical settings before deciding to pursue a PhD in 2023. Juan’s current research focuses on ethnic-racial identity development within societal, cultural, and interpersonal contexts for Latine adolescents and adults, ultimately with goals of understanding how these moments of identity exploration leads to a greater understanding of oneself, and how it informs socio-political action. Whenever Juan has time to relax, he enjoys learning guitar, spending time with his friends, going to concerts, and exploring new coffee spots.

Sarah Jennings
Sarah Jennings is a second-year doctoral student in the Personality, Development, and Health Psychology PhD program at Northwestern University. Her research in narrative identity examines how people construct evolving, internalized life stories that integrate past events, present states, and imagined futures into their sense of self and meaning in life. Specifically, Sarah is interested in the psychosocial processes of how cultural scripts and structural forces shape narrative identity development, engaging both mixed-method and qualitative methodology in the study of identity from multiple intersecting levels of analysis. Her interdisciplinary vision for her work centers intersectionality, critical frameworks, and feminist approaches with the hopes of exploring how narrative can be a vehicle for individual and societal transformation to create new realities, futures, and selves. Her past work studied autobiographical reasoning and its relationship to well-being in emerging adults and midlife adults, as well as how social identity marginalization shapes narrative identity development and adjustment in college contexts. In her free time, Sarah enjoys film and theater, swapping stories with friends and family, and cheering on her hometown Philadelphia sports teams.
