Optimizing the Placement of Automated External Defibrillators in Marin County, CA — A Location-Allocation Analysis
This study evaluated the spatial and temporal coverage of public automated external defibrillators (AEDs) in Marin County, California, from 2019 to 2024 to determine whether existing AEDs were optimally located to maximize Out-of-hospital cardiac arrest (OHCA) coverage and to identify additional placement opportunities. We defined coverage as the proportion of OHCAs occurring within 100 meters…
Factors Associated with Latent Tuberculosis Treatment Initiation for Primary Care Patients in a Large Health System
Background: One of the mainstays of eliminating tuberculosis as a public health threat is through the treatment of latent tuberculosis infections (LTBI). To determine ways to improve LTBI treatment rates, we assessed factors associated with LTBI treatment initiation in United States (US)-based primary care clinics. Methods: Using electronic health record data, we identified adult primary…
Pediatric Oncology and Bone Marrow Transplant ICU Patients in Children’s and General Hospitals
Pediatric oncology and hematopoietic stem cell (HCT) care in the US is increasingly provided at children’s hospitals (CH), but many children still receive care at general hospitals (GH). Little is known about the characteristics of pediatric oncology and HCT patients treated in intensive care units (ICUs) at these institutions, or how outcomes differ for patients…
Receipt of Glucagon-Like Peptide-1 Receptor Agonists Among rural Patients with Obstructive Sleep Apnea and Excess Weight
Successful weight loss is more difficult for those with OSA, and gaps in weight management care are more pronounced in rural areas. Glucagon-Like Peptide-1 Receptor Agonists (GLP-1RAs) are promising agents to improve the effectiveness of weight management care patients with OSA and excess weight living in rural areas. We sought to test the association of…

Advancing Sexual Health for Cisgender Women: A Series of Studies Addressing Doxycycline Post-Exposure Prophylaxis, Vaginal Health, and Antimicrobial Resistance in Kenyan Women
Abstract Globally, high rates of sexually transmitted infections (STIs) persist even in the face of effective antibiotic treatment, with young women living in Africa facing a disproportionate burden. Sexually transmitted infections can lead to dire reproductive health consequences for women, including severe complications and significant economic burdens related to lost productivity and quality of life….
Early Childhood Education and Violence Prevention Across the Life Course and Generations
Abstract High-quality early childhood education may buffer against social and structural drivers of interpersonal and self-directed violence. This dissertation examined associations of Head Start—a large-scale early childhood education program for low-income children, launched in 1965 as part of the War on Poverty—and violence-related outcomes within and across generations. Intragenerational analyses found that attending Head Start…
Retention, mental health, and scalable treatment programs for youth living with HIV: An exploration of social and behavioral influences
Abstract Background: Adolescents and young adults living with HIV (AYLHIV) are at higher risk of negative health outcomes including disengagement from care, viral non-suppression, depression, and anxiety. This additional risk may be partially explained by the substantial changes in relationship structures, cognitive functioning, and independent self-management of HIV that occur throughout adolescence, but age-specific data…
Workplace injuries, early opioid prescribing, and disability in Washington State
Abstract INTRODUCTION: From the late 1990s through early 2010s, opioid prescribing increased dramatically in workers’ compensation (WC) systems, following national trends within the United States. The increase in opioid prescribing coincided with an increase in overdose deaths and morbidity linked to prescription opioids. While subsequent policy interventions including Prescription Drug Monitoring Programs (PDMP) and updated…
The methamphetamine use continuum and associated risk factors among cisgender men and transgender people with male sex partners
Abstract The methamphetamine (meth) epidemic in the United States (US) disproportionately impacts cisgender men and transgender people who have sex with males (CMTSM). This confers a disparate burden of meth-related sequelae, including cardiovascular, cognitive, and psychiatric conditions. Among CMTSM, meth is syndemic with HIV, posing a threat to the US initiative of Ending the HIV…
Examining Mental Health and Recovery Following School Shootings
Abstract This dissertation examines the mental health impacts of school shootings in the United States, with a particular focus on the effects on subpopulations, gaps in existing research, and the importance of incorporating survivor perspectives into study design, interpretation of findings, and dissemination. Since 1999, over 380,000 students have been exposed to firearm violence while…
