The Biobehavioral Branch supports research into the interplay of behavioral, biological, and environmental determinants of health and wellness across populations. The research focuses on the following areas:

Digestive Disorders Unit (Principal Investigator: Dr. Wendy Henderson)

This research focuses on improving the understanding of the mechanisms involved in symptom distress related to digestive disorders, specifically the biobehavioral relationships between inflammation and patient symptoms. The long-term goal of this research is to identify genetic or other biologic/physiologic factors to improve diagnoses and predict patient-related clinical outcomes. 

Clinical Neuroscience Unit

This research area examines the influence of circadian rhythms on symptoms such as pain and fatigue across conditions and populations. Research includes studies examining genomic profiles to illuminate the determinants of sleep and circadian rhythm in prostate cancer patients prior to and throughout the treatment process.
