Soojung Ahn, PhD, RN

Postdoctoral Scholar

Soojung Ahn Dr. Soojung Ahn is a postdoctoral scholar under the mentorship of Dr. Mulubrhan Mogos and Dr. Mariann Piano at Vanderbilt University School of Nursing. Her research interests include an emphasis on cardiovascular disease prevention, subclinical biomarkers, and lifestyle modification. She is particularly interested in the population of family caregivers of patients with chronic illness. Utilizing cardiovascular subclinical markers (e.g., arterial stiffness and blood pressure variability), her research aims to investigate the role of psychological and behavioral factors, such as depression, caregiver stress, sleep deprivation, and physical inactivity, in caregivers’ cardiovascular health. Dr. Ahn earned her doctoral degree from the University of Virginia School of Nursing where she conducted a dissertation study that focused on the associations among psychological distress, sleep quality, and 24-hour blood pressure variability in family caregivers. Expanding her dissertation study, Dr. Ahn plans to conduct a pilot study that examines temporal associations and clustering patterns of psychological symptoms, sleep quality, and levels of physical activity in relation to cardiovascular disease risk among family caregivers of older adults with multiple health conditions.
