Joshua M. Smyth

Joshua M. Smyth's research focuses on how people's emotions, stress, and health behaviors (like physical activity and eating) fluctuate in daily life, often tracked using smartphone-based surveys and wearable sensors (a method called ecological momentary assessment or ambulatory assessment). His work also examines mobile health interventions designed to improve well-being, physical activity, and mental health, including in populations such as adolescents, breast cancer survivors, and young adults. This research combines methods from psychology, behavioral medicine, and digital health to understand and intervene in everyday psychological and physical health patterns.

Publication output has declined somewhat over the past decade, from around 35-40 papers per year in 2017-2018 to roughly 17-24 per year in recent years, with a 5-year average of about 18 publications annually.
