I grew up in northern New Jersey (mostly), the second of four brothers. I graduated from M.I.T. with degrees in mechanical engineering and biology, and received my medical degree from the Duke University School of Medicine. I came to Johns Hopkins in 1987 for Pediatric Residency training, and have been here ever since. I completed fellowship training in Pediatric Endocrinology and joined the faculty in 1993. During my early years on the faculty, my efforts were basic science-focused. I spent 5 years of additional research training after my fellowship in the Department of Biological Chemistry, and then had my own laboratory for a number of years. My research interest was the molecular basis of insulin resistance and obesity, with studies examining the role of the adipocyte in these states. However, a number of years ago now I realized that my greatest professional enjoyment came from my interactions in a clinical context with medical students, residents, and fellows, and I changed my professional focus to be much more teaching centered. I supervise and precept pediatric endocrine fellows, pediatric residents, and medical students caring for pediatric endocrine patients in both the inpatient and outpatient settings. I see patients with the complete range of hormonal concerns in an active general pediatric endocrine clinic, and follow children with type 1 and type 2 diabetes mellitus in the comprehensive pediatric diabetes clinic at Johns Hopkins. I also work closely with pediatric residents and medical students as a frequent ward and teaching attending on the general pediatrics inpatient service. I have been the fellowship director for the Pediatric Endocrine training program since 2003.
I live in Towson with my wife Sara, who is the lab manager for the Dietz lab in the Institute for Genetic Medicine at Hopkins. We have two daughters: Merrit is attending Towson University, and Hallie is attending Boston University.
I have played squash since my days at M.I.T., and more recently have spent much time running, competing in race distances from 5K to marathons.
