How their research is transforming health care
Sarah’s research and scholarly interests focus on advancing health promotion, disease prevention, and equitable access to high-quality pulmonary care. Her work emphasizes lung cancer screening, rural health disparities, and improving care delivery models for vulnerable and underserved communities. Through her leadership in Prisma Health’s Lung Cancer Screening Program and her involvement in Project GROW—a grant-funded initiative aimed at improving screening outreach in rural South Carolina—she has helped expand education, access, and early detection strategies across primary care settings.
Her research also explores the evolving role of advanced practice providers in pulmonary and critical care medicine, particularly through postgraduate training models. As the founder of the first Nationally Accredited Outpatient Pulmonary APP Fellowship, she has contributed to improving standardized clinical education, fostering multispecialty collaboration, and strengthening the pipeline of pulmonary APPs prepared to deliver evidence-based, high-quality care.
Sarah regularly presents at national conferences and contributes to publications, professional guidelines discussions, and multidisciplinary educational programs. Her ongoing work aims to reduce health disparities, enhance screening uptake, and elevate the clinical impact of advanced practice providers within complex pulmonary specialties.
