Research Topics

Dr. Leorey Saligan examines the nature and causes of fatigue in relation to cancer and its treatments. The purpose is to understand and identify biobehavioral mechanisms of fatigue in order to develop more effective ways to manage it and, as a result, improve patient outcomes. His research program is guided by the NIH Symptom Science Model.

Dr. Saligan is introducing clinically relevant approaches to phenotype cancer-related fatigue (CRF) to drive biomarker discovery. He is also leading studies to identify biomarkers of CRF and understand functional pathways to explain its cause. In addition, Dr. Saligan is conducting proof-of-concept clinical trials that target the biochemical and physiologic effects of active markers identified in CRF studies in order to validate their clinical relevance.

Biography

Dr. Saligan received his PhD in nursing from Hampton University. In 2007, he joined NINR as a postdoctoral fellow within the Symptom Management Branch, where he became a Lead Associate Investigator of a clinical trial involving individuals with fibromyalgia. In 2009, he became an Assistant Clinical Investigator and Principal Investigator of several clinical protocols, including:

  • Effect of Ketamine on Fatigue Following Cancer Therapy (15-NR-0037)
  • Investigating Molecular-Genetic Correlates of Fatigue Experienced by Cancer Patients Receiving Treatment (11-NR-0014)
  • Molecular-Genetic Correlates of Fatigue in Cancer Patients Receiving Localized External Beam Radiation Therapy (09-NR-0088)
  • Fatigue in Healthy Individuals (09-NR-0131)
  • Evaluation and Diagnosis of Potential Research Subjects with Pain and Fatigue Syndromes (08-NR-0132

Dr. Saligan became a tenure-track investigator in 2012 and expanded his research program to investigate the biobehavioral mechanisms of fatigue. He also serves as an officer within the United States Public Health Service.
