I am a licensed clinical psychologist in the University of Washington’s Department of Psychiatry and Behavioral Sciences, working in adult inpatient care within the Center for Behavioral Health & Learning. I bring specialized training in serious mental illness, inpatient psychiatric care, serving populations with comorbid substance use and/or medical complexity, and enjoy working collaboratively within multidisciplinary teams to optimize patient-centered care. I also bring a global public health background in improving service delivery and access in low-resource settings across Africa and Asia.
I graduated with a PsyD in clinical psychology from the University of Denver, after completing my pre-doctoral internship at Mt. Sinai/Elmhurst Hospital in New York. During this internship, I completed rotations in the adult inpatient unit, the child partial hospitalization program, psychiatric emergency room services, and the consultation-liaison psychiatric service, serving a patient population that is among the most ethnically and culturally diverse in the world. I am dedicated to providing high quality, empathetic, and innovative interventions to our inpatient population.
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 lab based at Fred Hutch Cancer Center develops and tests acceptance-based therapies delivered in digital and telehealth platforms. 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.

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.

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.
I am a trained Behavioral Scientist with a PhD in Health & Human Performance. The main goal of my work is to reduce substance-related harms and improve quality of life for people experiencing problems related to their substance use. I work closely with community members who use drugs to inform my line of research and address key needs identified. My primary appointment is at the Harm Reduction Research and Treatment (HaRRT) Center within the UW School of Medicine and hold an Affiliate Faculty appointment within the School of Public Health. My aim is to adapt, refine, and disseminate harm reduction programs through digital health interventions to empower individuals and ameliorate substance-related harms.
My scholarship is dedicated to reducing behavioral health disparities in Indigenous, immigrant and refugee communities. I have 13 years of experience and expertise in community-based participatory research (CBPR) science and practice, mixed-methods multi-level research design, cultural adaptation and translation of evidenced based interventions and culture-based practices, survey and measurement development, and dissemination and translation of findings. I am interested in examining culture-centered, land-based healing practices and mechanisms in addressing substance use, sexual health, and climate change impact.
