Dr. Ji’s program of research focuses on sleep health in community-based populations and in particular, the role of habitual daytime napping and nocturnal sleep patterns in cognitive impairments and psychological symptoms in children and adolescents. In addition, Dr. Ji’s research has integrated serum micronutrient status with sleep disturbances to understand lifestyle risk factors for neurobehavioral development in adolescents. As a nurse scientist with methodological expertise in technology-based interventions, Dr. Ji has also involved in symptom management programs for ethnic minority women. She teaches in the undergraduate program in the area of health, vulnerability, and diversity.
