Dr. Nelson received his Ph.D. in clinical child psychology from the University of Kansas in 2008 following a clinical internship at Cincinnati Children's Hospital Medical Center. He subsequently completed his post-doctoral fellowship in pediatric psychology in the Stanford University School of Medicine before joining the UNL faculty in 2009. He has served as the Associate Director of Clinical Training at UNL since 2012.
Dr. Nelson's research interests are in pediatric psychology. Specifically, his work focuses on the intersection between health and behavior with an emphasis on health promotion in children and adolescents. He is interested in understanding the factors that influence pediatric health and key health behaviors (e.g., sleep, diet, physical activity) as well as interventions to improve health through behavior change. In his current work, he is pursuing these interests by studying a variety of pediatric populations (e.g., children who are overweight, low-income families, youth in residential treatment, children and adolescents with chronic medical conditions, rural adolescents) using a variety of methods (e.g., electronic daily diaries, momentary assessment using smart phones, actigraphy, performance-based cognitive tasks, medical record review, blood analysis, surveys). Below is a brief description of projects currently underway or in preparation in Dr. Nelson's lab.
Executive Control and Adolescent Health. Project examining the role of executive control across development on adolescent health-related factors (e.g., weight status, diet, physical activity, sleep, stress reactivity, substance use, psychopathology), with an emphasis on the environmental context in which executive control and health interact. Collaboration with Developmental Cognitive Neuroscience Laboratory at UNL and Boys Town National Research Institute.
Pediatric Sleep and Psychopathology Project. Exploring relationships between children’s sleep and mental health symptoms. Specific studies include daily-level investigations of bidirectional effects between sleep and psychopathology, sleep intervention development, and evaluation of a brief sleep protocol for children presenting with disruptive behavior problems. Collaboration with Boys Town.
Pediatric Obesity Treatment. Project focusing on developing, refining, and evaluating evidence-based interventions for families presenting to an interdisciplinary pediatric obesity clinic. Collaboration with Children’s Hospital and Medical Center.
Stress, Sleep, and Minority Health Disparities. Project focusing on the effects of stress on critical health behaviors (e.g., sleep) and, ultimately, health outcomes among racial/ethnic minority families. Collaboration with Sociology faculty at UNL.
Pediatric Health Technology and Telehealth. Developing and evaluating novel technology applications and telehealth intervention for pediatric health problems (e.g., chronic migraine, congenital heart disease). Collaborations with Emory School of Medicine and Cincinnati Children’s Hospital faculty.
Dr. Nelson's teaching interests are in clinical and clinical child psychology. He teaches courses in child psychopathology and assessment, abnormal psychology, and child treatment.
