An endocrinology expert with more than 50 years of experience specializes in calcium and bone mineral metabolism, with extensive work involving osteoporosis, osteomalacia, vitamin D deficiency, calcium malabsorption, parathyroid disease, and kidney-related bone disorders. His background includes the hormonal regulation of bone formation and remodeling, particularly the roles of parathyroid hormone and insulin-like growth factor pathways in skeletal development, fracture healing, and the physiologic response of bone to mechanical loading and unloading. He also has prior expert witness experience involving endocrine and metabolic bone disease matters.

His areas of expertise include endocrinology, metabolic bone disease, renal osteodystrophy, osteoporosis, vitamin D disorders, intestinal calcium absorption, parathyroid hormone regulation, bone remodeling, and nutrition-related influences on bone health. Additional knowledge includes molecular mechanisms of vitamin D receptor function and hormonal disorders affecting bone mineral metabolism, along with research involving endocrine regulation of skeletal growth and tissue development.

In addition to bone and endocrine research, he has experience involving skin biology and calcium-mediated cellular differentiation, including keratinocyte differentiation, wound repair, and skin cancer development. His professional work has focused on endocrine and molecular pathways influencing bone development, tissue differentiation, and mineral metabolism. He holds a Bachelor of Arts in Biochemical Sciences, a Doctor of Medicine, and a Ph.D. in Biochemistry, and completed internship and residency training in internal medicine.
