Dr Raff's laboratory has two main research areas of interest. His basic research on the hypothalamic-pituitary-adrenal axis focuses on the short- and long-term consequences of neonatal hypoxia. His laboratory has discovered that activation of the synthetic pathway for corticosterone (the main glucocorticoid of the rodent) by neonatal hypoxia is mediated by a novel second-messenger cascade. 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.

Dr. Raff is heavily involved in medical, graduate, pharmacy and undergraduate education. He is Course Director of the second year medical student Endocrinology/Reproduction Integrated Unit. He teaches first year endocrine physiology to medical and pharmacy students and Advanced Endocrinology for graduate students and Endocrine Clinical Fellows. 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 role of androgens and corticosteroids in the development of the hypothalamic-pituitary-adrenal (HPA) axis 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.
