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.

Before joining this department, I completed my Ph.D. in clinical psychology at Purdue University, residency at the University of Washington, and fellowship at the University of Pennsylvania.
My research interests primarily center around romantic relationship functioning and personality disorder (PD) measurement. My line of PD research centers around how the use of a trait-based, dimensional approach to assessing and measuring PDs may increase construct validity, reliability, and diagnostic accuracy relating to PDs. My romantic relationship research centers around how romantic relationship functioning and interpersonal behaviors are associated with psychopathology diagnoses and symptoms.
As a clinician, I specialize in treating suicidality and self-harm using comprehensive Dialectical Behavior Therapy; in treating PTSD using Cognitive Processing Therapy and Prolonged Exposure; and in treating anxiety-related disorders using exposure therapies like Exposure and Response Prevention for OCD and Exposure for Social Anxiety. I am also passionate about providing couples’ therapy.

She has clinical expertise in disruptive behavior disorders, comprehensive assessment, Dialectical Behavior Therapy, Exposure Therapies, Parent Training, and Trauma-Focused Cognitive Behavioral Therapy.
Dr. Friesen’s research interests broadly focus on advancing knowledge of least restrictive interventions in acute and complex care contexts, trauma-informed care, and interventions designed to address children’s disruptive behavior problems. She has collaborated on and co-led efforts to design and implement a multi-tiered, Modified Positive Behavioral Interventions and Supports (M-PBIS) model of care aimed at increasing positive behavior interventions, reducing restraint and PRN use, and ameliorating racial gaps in care delivery.

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.
