Dr. Raff’s basic research focuses on the hypothalamic-pituitary-adrenal axis and the short-and long-term consequences of neonatal stress and therapeutics. His translational research focuses on the interaction of obesity and pain in human adolescents. His clinical research focuses on the development of diagnostic endocrine tests and, in particular, using the measurement of salivary cortisol to evaluate the hypothalamic-pituitary-adrenal axis in a variety of human diseases and stress models and the development of cortisol assays to use in ACTH stimulation testing.

Dr. Raff is heavily involved in medical, graduate, pharmacy and undergraduate education. He is Course Director Endocrinology/Reproduction Integrated Course for medical students in their preclinical phase. He teaches first year endocrine physiology to medical and pharmacy students and Endocrine Clinical Fellows. He is the course director of the Introduction to Organ Systems Physiology for first year graduate students. Dr. Raff is the author of two textbooks: Vander’s Human Physiology, an undergraduate textbook, and Medical Physiology: A Systems Approach, a medical student-level textbook. He also teaches Applied and Rehabilitative Systems Physiology at Marquette University College of Health Science. He was an inaugural inductee into the MCW Society of Teaching Scholars in 1991 and was elected to Alpha Omega Alpha as a Faculty Member by the MCW senior medical student class of 2005.

Laboratory Studies

• Evaluating the interaction of neonatal stress and common clinical interventions on the hypothalamic-pituitary-adrenal (HPA) axis and metabolism in an animal model of human prematurity.
• Studying the role of the HPA axis in relapse of opioid addiction in a rat model of sleep disruption.
• Using a newly developed liquid chromatography-tandem mass spectrometry (LC-MS/MS) method to measure salivary cortisol and cortisone in the diagnosis of Cushing’s syndrome.
• Evaluation of the ACTH (cosyntropin) stimulation test for the diagnosis of adrenal insufficiency utilizing new generation cortisol assays.
• Measuring serum and salivary biomarkers in patients with mild traumatic brain injury and obesity.
