He works clinically with this population and is also sought after by legal experts for consultation regarding PTHP. He served as a primary witness in one of the first US trials in which PTHP developed following a concussion/mild traumatic brain injury.  In addition, Dr. Batson provides medicolegal consulting services and manages multi-disciplinary evaluations for traumatic brain injury cases across the fields of endocrinology, neurology, neuroradiology and neuropsychology. He also works in collaboration with doctors in the fields of sleep medicine, neuropsychiatry and neuro-optometry, particularly with respect to traumatic brain injury related sleep, psychiatric and visual disorders.

He has generated a number academic writings on the topics of post-traumatic hypopituitarism (PTHP), selection criteria and eligibility for growth hormone replacement in patients with hypopituitarism, the management of hypogonadotropic hypogonadism in type 2 diabetes mellitus, a review of triiodothyronine (T3) therapy in hypothyroidism, the diagnosis and management of hyperaldosteronism, and guidelines for the diagnosis and management of polycystic ovary syndrome. He has also conducted literature reviews in the areas of psychotic disorders following traumatic brain injury, hypogonadotropic hypogonadism following traumatic brain injury, and a review of the cosyntropin stimulation test in secondary adrenal insufficiency diagnosis. Most recently, he served as a content expert for a  Cochrane Systematic Review  on biofeedback and IBS and co-authored a chapter on the comprehensive treatment of osteoarthritis published in  Metabolic Therapies in Orthopedics recently featured in the Hopkins Reader, Johns Hopkins Medicine. He is the recipient of the 2012  Natural Standard Research Collaboration  Award for excellence in multidisciplinary, evidence-based research practices, healthcare communications and information. 

He is one of the only licensed naturopathic physicians in the United States with formal university training and mentorship in conventional endocrinology and is a diplomate in endocrinology with distinction. His clinical practice focuses on evaluating and managing select endocrine conditions including hypopituitarism, hypothyroidism, male and female hypogonadism, and polycystic ovarian syndrome, as well a screening for a variety of endocrine conditions with referral/coordinated care involving generalists and specialists in the fields of endocrinology and neuroendocrinology.
