Bianca D.M. Wilson

Bianca D.M. Wilson, PhD, is an Associate Professor in the Department of Social Welfare at the Luskin School of Public Affairs and an affiliate faculty member of the California Center for Population Research at UCLA. Her research explores the relationships between culture, oppression, and health. Dr. Wilson examines LGBTQ economic instabilities and involvement with systems of care and criminalization, with a focus on the ways racialization, sexual orientation, gender identity, and gender expression play a role in creating disproportionality and disparities.

Notably, she was the lead investigator on the first study to establish population estimates of how many LGBTQ youth are in foster care and has led similar work in juvenile criminalization. Similarly, she has led the largest qualitative study of the life and needs of LGBTQ people experiencing economic insecurity. Acknowledging the impact of this work, she was awarded the Distinguished Contribution to Public Policy Award by the American Psychological Association Division 44 (Society for the Psychology of Sexual Orientation and Gender Diversity). Underlying her substantive works on LGBTQ, health, system involvement and economic security is her attention to sexual orientation, gender identity and gender expression (SOGIE) data collection and data policy. She has conducted SOGIE measurement research among youth and adults and continues to work with local, state and federal government efforts on increasing and improving LGBTQ inclusive data collection. She served on the National Academy of Sciences, Engineering and Medicine (NASEM) Consensus Panel on the Measurement of Sex, Gender and Sexual Orientation- a report commissioned by the National Institutes of Health in the interest of informing data policy and practices in federal data collection. She is currently serving as a scientific committee member of NASEM’s Assessment of NIH Research on Women’s Health consensus study.

She was previously a Senior Scholar of Public Policy at the Williams Institute on Sexual Orientation and Gender Identity Law and Public Policy at the UCLA School of Law, and before that an Associate Professor in the Department of Psychology at California State University, Long Beach. Dr. Wilson earned a Ph.D. in Psychology from the Community and Prevention Research program at the University of Illinois at Chicago (UIC) with a minor in Statistics, Methods, and Measurement, and received postdoctoral training at the UCSF Institute for Health Policy Studies and the UCSF Lesbian Health and Research Center through an Agency for Health Research and Quality (AHRQ) postdoctoral fellowship.

Yeon Jae Hwang

Yeon Jae Hwang is an incoming first-year doctoral student in the Department of Social Welfare at UCLA Luskin School of Public Affairs. She received her Bachelor of Arts in English from Hankuk University of Foreign Studies and her Master of Social Welfare from Yonsei University, South Korea.

As a queer person of color, she continuously sought ways to support and empower marginalized people’s voices during her undergraduate, mostly spending days on the street demonstrating and fostering ties with other advocates in the South Korean community. The number one question that opened her journey to academia was, ‘how does one not conventionally categorized survive in such a heteronormative and conservative society?’

Thus, her main objective as a social welfare student in her master’s was to initiate discourse in Korean academia by highlighting the marginalized groups’ existence and revealing the discriminatory reality they face via quantitative and qualitative research. Now she is engaged and actively participating in various research teams and projects, especially regarding LGBTQ+ research.

Her research interests center on sexual minorities subjected to social discrimination and systematic oppression due to their multiple intersecting identities- including stigmas, prejudice, and microaggression. Her views focus on the systems in which such groups are placed by exploring the forces and powers within diverse levels of context.

Jianan Li

Jianan Li (she/her) is an incoming first-year doctoral student in the Department of Social Welfare of the Luskin School of Public Affairs. She received her Bachelor of Law in Social Work from Southwest Petroleum University and her Master of Social Work concentrating in Policy Practice and Aging from Columbia University. She has practiced fieldwork in a variety of settings including schools, communities, social work service centers, and government departments. The practical experience has led her to conduct research projects among different populations and to focus more on the aging population, especially on improving the well-being of disadvantaged older adults.

During her master’s degree, Jianan interned at the New York City Department for the Aging. There, she participated in several pilot research projects focused on older adults, working on exploring ways to improve older adults’ mental health by mitigating the stigma attached to mental health services among professionals and older adults. She also worked as a research assistant at the Columbia Population Research Center, where she contributed to interviews and data analysis for the New York City Longitudinal Survey of Wellbeing, a longitudinal research project dedicated to tracking economic and social well-being in New York City.

Her areas of interest include examining the factors affecting the quality of life of older adults with long-term care needs in different settings to improve the current care system, and understanding the effects of productive engagement in later life to enhance the health and well-being of older adults.

Hillary Peregrina

Hillary Nicole Peregrina, MA, MSW (she/her/hers) is an incoming first-year doctoral student committed to addressing mental health and psychosocial development among BIPOC children and adolescents, with a particular focus on the Filipino American community. She obtained her Master of Arts in Social Work (Clinical Concentration) from the University of Chicago’s Crown Family School of Social Work, Policy, and Practice. She also previously earned a Master of Arts in Asian American Studies from San Francisco State University and a Bachelor of Arts in Psychology from Loyola Marymount University.

Prior to entering the field of Social Work, she taught Ethnic Studies courses at San Francisco State University and San Francisco Unified School District through Pin@y Educational Partnerships. Her social work experience encompasses a range of youth development roles including administrative non-profit research and program evaluation and counseling services for children and adolescents ages 8-18.

Her central research questions focus on the impact of racial discrimination and critical racial consciousness on various developmental outcomes including mental health, ethnic/racial identity, family processes, civic engagement, and racial solidarity. She hopes to explore how contextual factors including discrimination, family and/or school ethnic-racial socialization, im/migration, diaspora, and other social determinants impact the formation of critical racial consciousness. She has previously published on various public health issues that impact Asian American communities across the lifespan including family social support, psychosocial wellness, type 2 diabetes and breast cancer among older Asian Americans, and civic engagement among emerging young adults. Her research interests are an interdisciplinary blend of her experience in Social Work and Ethnic Studies. Ultimately, she hopes to use various forms of research to advocate for health equity, translate findings into public policy recommendations, and inform clinical and community-based interventions.

Tatiana Londoño

Dr. Tatiana Londoño is a first-generation Latina born in Colombia and raised in Miami, Florida. Dr. Londoño graduated from Vassar College with a B.A. in Neuroscience and Behavior and from The University of Texas at Austin with an M.S.S.W. and then her Ph.D. Throughout her career, she has received funding from various sources such as OLLI NOVA Diversity Scholarship, St. David’s Foundation, Integrated Behavioral Health Scholars Program, and QuestBridge.

Tatiana Londoño’s scholarship focuses on the mental health and psychosocial wellbeing of Latine/x immigrant youth and their families, with an emphasis on the experiences and impact of migration. Specifically, her work explores how Latine/x immigrant youth and families navigate and adapt to the psychosocial consequences of migration and resettlement. She is particularly interested in how these experiences contribute to various outcomes, such as distress and post-traumatic growth, and how family processes can mitigate some of these outcomes. Her long-term goal is to incorporate her research into brief preventative interventions accessible to Latine/x immigrant populations in the U.S. Her work is published in Family Process, The American Journal of Drug and Alcohol Abuse, Health Psychology, Journal of Adolescent Research, Child and Adolescent Social Work Journal, and Social Work in Mental Health. She has also published policy and research briefs with the Children’s Defense Fund and the Center on Immigration and Child Welfare.

Dr. Londoño is currently involved in several National Institutes of Health (NIH)-funded studies concerning the mental health and psychosocial well-being of Latine/x youth and their families. She is using a mixed-method approach to explore the effects of migration and immigration detention on asylum-seeking children and families from Central America. Specifically, she is analyzing 1) migration trauma exposure and mental health outcomes among immigrant youth; 2) how migration shapes parent-child relationships; and 3) different trajectories of wellbeing among youth in the U.S. resettlement context and environmental contexts (e.g., neighborhood, school, immigration enforcement) that contribute to these trajectories. In addition to this project, she is currently investigating the cultural adaptation and implementation of a parenting intervention that integrates experiences of immigration-related challenges, discrimination, and biculturalism.

Dr. Londoño’s previous research projects include: (1) exploring why adolescent Latinas attempt suicide more than other females;  (2) examining the effects of immigration enforcement on U.S. citizen children of undocumented Mexican parents; (3) investigating service experiences of youth transitioning from child to adult mental health systems; (4) studying depression and suicidality among Mexican-American children and youth; and (5) assessing smoking dependence among Spanish-speaking Latine/x smokers.

Dr. Londoño also engages in needs assessment and evaluation research related to the communities she serves. She led the analysis of a campus-wide survey on assessing the needs of undocumented students at UT Austin and, with the Rooted Collective Task Force, drafted a proposal in support of a center for undocumented students. Dr. Londoño is also evaluating the Mental Health Collaborative at Girasol, a program that serves Texas immigrant children and families and educates service providers working with immigrant populations.

In the community, Dr. Londoño has worked in various settings such as schools, domestic violence agencies, and integrated behavioral health primary care clinics providing counseling, psychoeducation, and case management services to mostly Spanish-speaking families who experienced immigration-related trauma. Tatiana continues to volunteer her time to support immigrant families in detention with their credible fear interviews and orient asylum-seeking families at immigrant resource centers. She is currently the lead consultant on a project with New Mexico State University creating a trauma-informed training series for service providers working with Latine/x immigrant populations. This work is funded by the W.K. Kellogg Foundation.

Professor Londoño teaches the following courses: 211A: Human Behavior in Social Environment.
