Sangchoon Jeon, PhD

Senior Research Scientist


Dr. Sangchoon Jeon is a biostatistician who was trained in statistics (BS, MS) and epidemiology (PhD). His dissertation was evaluating cancer-related symptom changes using alternative survival analysis approaches with considering important statistical assumptions. Primarily, Dr. Jeon has actively participated in evaluating cognitive behavioral interventions for adolescents with diabetes, sleep disturbance in heart failure patients, symptom management in cancer patients, and an exercise intervention for breast cancer survivors. Jeon is currently participating as biostatistician on the method core for the Yale Center for Sleep Disturbance in Acute and Chronic Illness.

He is currently interested in parametric and non-parametric methods for analyzing circadian rhythmicity of continuous motor activity, and prediction of symptoms and mortality in heart failure patients. Notably, his recent publications in evaluating actigraph data in heart failure patients show the discrepancy between actigraphy and polysomnography in sleep disturbance and the associations between RAR metrics, daytime symptoms, and functional performance.
