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.
Dr. Katherine Seldin is a faculty member and licensed clinical psychologist in the University of Washington’s Department of Psychiatry and Behavioral Sciences. Before joining this department, Dr. Seldin completed her PhD in Clinical Psychology at the University of Washington, residency at Northwestern University Feinberg School of Medicine, and fellowship at the University of Ilinois Chicago.
Dr. Seldin specializes in delivering evidence-based cognitive behavioral therapies (CBTs), including mindfulness-based and exposure-based psychotherapies such as Acceptance and Commitment Therapy (ACT) and Exposure and Response Prevention (ERP). Her research interests include mood disorders, sleep, digital intervention, emotional impulsivity, and ecological momentary assessment methodology.
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.
Christina Warner, MD (she/her) is the attending psychiatrist for the Early Psychosis Clinic and Partial Hospitalization Program at Seattle Children’s Hospital. She has clinical expertise in mood disorders, psychosis spectrum disorders, First Episode Psychosis, chronic suicidality, mood dysregulation, neurodiversity, and Dialectical Behavior Therapy.
Dr. Warner is a Washington native and graduate of the Seattle Public School system with a vested interest in expanding access to high quality mental health care in her community.
I am a child and adolescent psychiatrist committed to improving outcomes for young people who face complex difficulties and systemic barriers. As a clinician, I aim to establish meaningful therapeutic relationships with young people and those supporting them, while also working to advocate for public policy and health systems that improve access to quality mental healthcare.
My main role includes providing inpatient care to older adolescents at the Child Study and Treatment Center through the Behavioral Health Administration, Washington State Department of Social and Health Services, and acting as training lead for psychiatry at this site. My clinical interests include the transition from adolescence to adulthood, the emergence of mood disorder and psychosis, early intervention for personality disorder, and developmental disabilities. I have academic interest in medical education, health service development, and the social determinants of mental health.
My interests focus on understanding etiology of substance use among adolescents and young adults, high risk events and the development of brief intervention and prevention efforts to reduce substance related harm. I have worked for over 20 years conducting research in governmental, private and academic settings to assess needs, assist in policy decisions and design intervention and prevention efforts. I am keenly interested in exploring opportunities to implement evidence-based approaches to enhance policies and practice.
My research broadly aims to better understand the etiology of depression and risk behaviors such as suicide and substance use across development, and translate findings to inform prevention and intervention strategies for youth and families. My work focuses on partnering with communities and primary care clinics to improve access to and use of effective mental health services.
My current projects include studies focused on adapting and evaluating suicide prevention intervention and implementation strategies for use with adolescents and their families in primary care and outpatient medical settings, including developing and adapting brief, just-in-time, and digital interventions to expand access to services.
In addition to research, I am also a clinical psychologist in the Mood and Anxiety Disorders Program and the Crisis Care Clinic at Seattle Children’s Hospital.
Dr. Connor Gallik, PhD, is the attending psychologist for the Adolescent Program on the Psychiatry and Behavioral Medicine Unit at Seattle Children’s Hospital and Acting Assistant Professor in the Department of Psychiatry and Behavioral Sciences at University of Washington.
Prior to joining the staff and faculty at Seattle Children’s/UW, Dr. Gallik completed his graduate education at the University of Connecticut with an emphasis in child and adolescent clinical psychology. He completed his clinical internship at Pacific University’s Psychology and Comprehensive Health Clinic and went on to complete a postdoctoral fellowship in clinical psychology at Seattle Children’s Hospital with an emphasis in DBT and inpatient care.
His research focuses on understanding factors related to the mental health and wellbeing of transgender and gender diverse (TGD) TGD youth and evidence-based practice on inpatient units. Clinically, he is interested in working with children, adolescents, and their families, with a focus on TGD youth. Dr. Gallik also provides training in TGD affirming care for mental health and medical professionals and speaks to community audiences about supporting transgender youth.
