As a child and adolescent psychiatrist at the Child Study and Treatment Center, I am deeply inspired by the resilience of the youth we serve and by the collaborative spirit of our multidisciplinary teams. My work is grounded in curiosity, compassion, and respect for the complex systems that shape young people’s lives. My approach integrates evidence-based psychopharmacology with developmental and trauma-informed care, while always centering around the individual’s unique story and strengths. I value the relational and systemic dimensions of psychiatry: the interplay between family, community, and policy that influences recovery and growth. The multidisciplinary, relational model at CSTC reflects these values and continues to shape how I think about psychiatry: not only as a science, but as a deeply human endeavor.
My research and clinical interests include third-wave, cognitive-behavioral interventions for adolescents and young adults, family-based and parenting-related support for families of youth engaging in risky or challenging behavior, suicide prevention, prevention of child maltreatment, increasing equitable access to evidence-based services, and effective collaboration with clients who have been labeled as “resistant” by prior treatment providers.

I am an Acting Assistant Professor in the Department of Psychiatry and Behavioral Sciences at the University of Washington, primarily working clinically at Harborview Medical Center. I work with the Recovery Clinic, Intake and Brief Intervention Services (IBIS), the Behavioral Health Integration Program (BHIP), and Addiction Consult Service.
I am fellowship-trained in Addiction Psychiatry, and board certified in both general and addiction psychiatry by the American Board of Psychiatry and Neurology.

I believe quality healthcare is a human right for all people and am excited help make that a reality as part of the Harborview system.
My lab develops and tests acceptance-based therapies delivered in digital and telehealth platforms, with a focus on addressing health disparities. The most preventable causes of premature death and human suffering are cigarette smoking and obesity. To this end, my research team focuses on designing, developing, and testing AI-based chatbot, smartphone app-delivered, and telephone coach-delivered contextual behavioral interventions for smoking cessation and for weight loss. Research aims include main outcome comparisons, mediators, moderators, intervention engagement, and therapeutic process predictors of outcome. This research is currently supported by multiple NIH R01-level grants. Our lab’s latest grant focuses on testing a smartphone app for helping American Indians and Alaska Natives stop smoking commercial cigarettes.

Dr. Dahyeon Kang is an Assistant Professor at the University of Washington School of Medicine. She earned her doctoral degree from the University of Illinois at Urbana-Champaign, where her work focused on the etiology of alcohol and substance use disorders through multimodal research methods, including alcohol administration, neuroimaging, transdermal biosensors, and ecological momentary assessments. At the University of Washington’s Department of Psychiatry, Dr. Kang investigates how individual and social factors interact to influence alcohol and cannabis use behaviors.
Dr. Clausell earned his doctoral degree in Clinical-Community Psychology from the University of Illinois at Urbana-Champaign in 2011.

Dr. Sandel-Fernandez’s research is focused on predicting impulsive and risk behaviors as they occur in people’s daily lives. She has conducted numerous studies using ecological momentary assessment (EMA) and self-monitoring data from therapy to build person-specific models of symptom dynamics including self-harm, substance use, and suicide attempts.
Dr. Sandel-Fernandez often takes an idiographic (person-specific) analysis approach to answer the question of when in time a person is most at risk for engaging in behaviors they would like to avoid, based on their context, emotions, and personal triggers. Her career goal is to improve treatment outcomes by tailoring evidence-based care to people’s diverse symptom experiences.
As a clinical and quantitative psychologist, my work bridges statistical practice and psychological theory to better identify for whom, under what conditions, and why substance-related health disparities are greatest across development. My substantive research seeks to understand how individual differences in stress and developing self-regulation shape substance use and disorder from adolescence through young adulthood, and how these associations explain substance use disparities among sexual and gender minoritized communities. Stemming from this work, my methodological research is centered on improving the analysis and interpretation of nonlinear effects spanning parametric and non-parametric methodologies.
