Philosophy of Care 

I pursued training in both medicine and scientific research to combine my love of biology with my desire to help others. My goal as a physician is to give patients and families the information and guidance they need to make the best decisions for themselves. My goal as a scientist is to study patients with reproductive endocrine conditions to answer both basic questions about how the reproductive endocrine system works and how puberty starts, and practical questions that can have a direct impact on patient care.

Professional History

I am a pediatric endocrinologist and translational researcher with an interest in the reproductive endocrine system. In both my clinical practice and my research, I focus on how the reproductive endocrine system develops and functions before birth, in infancy, at puberty, and through adolescence and adulthood. I treat and study conditions that interfere with the function of the reproductive endocrine system; these conditions can cause disorders of sex development, differences in the development of the genitals, precocious or delayed puberty, and/or issues with fertility. My research focuses on the causes of these conditions, the impact of these conditions on patients, developing potential new diagnostic tests, and evaluating treatments for these conditions.
