Chenglin Hong is a PhD Candidate in Social Welfare at UCLA. Trained as a social worker, Chenglin’s research focuses on addressing health inequities among sexual and gender minority and other LGBTQ+ populations. His work is centered primarily on the development and testing of interventions that aim to improve sexual health and mental health outcomes among gay, bisexual, and other sexual minority men (SMM), with a particular focus on HIV and intimate partner violence (IPV) in the U.S. and globally. Chenglin’s work lies at the intersection of social work, public health, psychology, and data science, with the aim of developing interventions that disrupt violence, stigma, HIV, and other syndemic conditions among the SMM communities. He is particularly interested in examining the feasibility and acceptability and developing and testing eHealth, mHealth, and other technology-based interventions and data science approaches (e.g., machine Learning, natural language processing) to promote IPV help-seeking and HIV prevention services such as pre-exposure prophylaxis (PrEP) among SMM.

Chenglin’s mixed-method dissertation titled “Utilizing Machine Learning and Technology-Based Intervention for IPV and HIV Prevention among SMM” was funded by the American Psychological Association (APA) Science Directorate, the Society for the Psychological Study of Social Issues (SPSSI), the UCLA Dissertation Year Fellowship program, and received honorable mention in the inaugural Grand Challenges for Social Work Doctoral Award.

Since he started the Ph.D. program, Chenglin has published over 30 peer-reviewed articles and presented more than 40 abstracts at leading national and international conferences. As a global health researcher, he has established collaborations with researchers from the University of Michigan, the University of Washington, Emory University, and collaborators in China, Ukraine, and Kenya. His current work also includes community engagements with providers and partners in community organizations such as the Los Angeles LGBT Center. Before UCLA, he received his Master of Social Work and Master of Public Health (MSW/MPH) from the University of Washington (Seattle).

Judith L. Perrigo

/in , , , /by

Judith (Judy) Perrigo is an Assistant Professor in the UCLA Luskin School of Public Affairs Social Welfare Department. Additionally, she serves as the Research Director for the Data Informed Futures (DIF) project at the UCLA Center for Healthier Children, Families, and Communities and assumes the role of Social Work Training Director within the UCLA Leadership Education in Neurodevelopmental Disabilities (LEND) clinic. Drawing from over two decades of clinical experience working with children and families in Los Angeles County, her scholarship and teaching revolve around prevention and early intervention (PEI) strategies aimed at addressing societal challenges, particularly those impacting early childhood.

 

Dr. Perrigo specializes in advancing holistic wellbeing for young children aged birth to 5 years. Her research encompasses various facets of early childhood, including mental health, socio-emotional development, early educational experiences, access to public services, and economic security. Her overarching objective is to identify both protective and risk factors contributing to childhood wellbeing, such as systemic challenges like socioeconomic and ethnoracial disparities and inequities. She approaches this goal through the lens of equitable PEI strategies and utilizes a range of research methodologies, including qualitative, mixed-methods, and quantitative approaches, thoughtfully selected to align with the unique demands of each research inquiry.

 

Her research agenda can be divided into two primary streams. The first focuses on transforming early childhood ecosystems, while the second delves into the impact of policies on families with young children facing poverty and material hardships. Among Dr. Perrigo’s ongoing research projects is a series of descriptive studies examining holistic wellbeing trends among kindergarten populations across the United States. These studies encompass facets such as physical and mental health, socio-emotional skills, and cognitive development. Another notable project is a multi-year, randomized controlled trial testing the impacts of guaranteed income receipt on early childhood development and various aspects of material hardship and poverty. Additionally, Dr. Perrigo is involved in research examining the experiences of young neurodivergent children within medical, mental health, and educational systems.

 

Dr. Perrigo is also deeply committed to collaborating with and serving communities to tackle local, social needs that can be explored through research. A key facet of her commitment lies in making sure that research findings are strengths-oriented, culturally humble, and accessible to a broad range of audiences. Support for her work comes from the Society for Research in Child Development, First 5 Orange County, Conrad N. Hilton Foundation, the Council on Social Work Education, and Los Angeles County.

 

In addition to her scholarship, Dr. Perrigo places a strong emphasis on engaging and mentoring student research collaborators. She teaches courses on social welfare practice and infant and early childhood mental health. Her teaching approach highlights the historical and structural forces that underlie both oppression and opportunity. Through her collaborative guidance, students develop practical, meaningful, and pertinent knowledge and skills that resonate within the realm of social justice and welfare.

Shannon L. Dunlap

/in /by

Shannon’s research is interdisciplinary and centers on adolescent and family development, mental health, stress and support. Her mixed-methods dissertation uses a life history calendar qualitative approach to interview transgender adolescent-parent dyads to explore their stress and support experiences across the adolescent life-span. Additionally, her dissertation includes a quantitative survey to further describe adolescent and parent perceptions of current adolescent psychological distress and school experiences. This research is important because it explores the role of parent- adolescent stress and support for adolescent gender identity development and affirmation.

Shannon earned her MSW from the University of Southern California and spent the 8 years prior to her doctoral training as a clinical social worker with children, families and adolescents. Specifically, she has worked as a clinical social worker within the field of child-adolescent mental health, LGBT adolescent mental health and youth HIV. During her PhD training, Shannon coordinated multiple research projects which included developing research protocols, collecting both quantitative and qualitative data and grant writing. Shannon has developed expertise in qualitative methodology and analysis, family mental health and qualitative dyadic analysis. Shannon used her clinical social work and research experiences within her teaching. During her doctoral education, she taught both MSW and Public Affairs undergraduate courses including human behavior, child and adolescent psychopathology and research methods.

Shannon received funding for her work from the American Psychological Foundation Roy Scrivner Memorial Research Grant and a National Research Service Award (NRSA) F31 predoctoral fellowship from NICHD. Shannon’s funding enabled her to expand her work to explore transgender adolescent-parent stress and support outside the contexts of her dissertation. During her doctoral studies and through her F31, she has collaborated with and been mentored by scholars across multiple institutions including UCLA, USC, Children’s Hospital Los Angeles, Pitt and University of Hawaii. Through these collaborations, she published a manuscript as a lead author in the Journal of Sexuality Education and has collaborated on multiple manuscripts published in AIDS Care, Substance Use and Misuse, Journal of Social Work Practice in the Addictions, and LGBT Health. Shannon plans to apply knowledge gained to: (1) develop larger grants and context specific interventions to support transgender children, adolescents and their families across multiple social domains; and (2) build upon the broader field of child, adolescent and family research and health.
