Dr. Sarah N. Arpin is an Associate Professor of Psychology at Gonzaga University, where she leads the Social Emotions, Relationships, and Health Research Lab. She earned her Ph.D. in Applied Psychology from Portland State University in 2015, with a specialization in Social Psychology and Quantitative Methods. Dr. Arpin's research bridges social and health psychology, examining how close relationships—particularly intimacy and loneliness—shape health and well-being. She focuses on the pathways through which social connection and disconnection influence health behavior outcomes such as substance use, sleep, and emotion regulation. Much of her work applies these insights to real-world contexts, including military populations, the workplace, and daily interpersonal interactions.
