Research Interests
My area of research interest is in early origins of polycystic ovary syndrome (PCOS). My research to date has concentrated on the metabolic and reproductive phenotypes of girls who may have increased risk - daughters of affected women and girls with excessive weight gain during childhood and puberty. Our studies of early reproductive and metabolic findings in these at-risk girls provides a unique opportunity to better understand the ontogeny of this syndrome.
I have a general pediatric endocrine clinic in which I care for children with a variety of endocrine disorders, including thyroid, puberty, growth, adrenal, and pituitary disorders. In addition, I see patients in our multidisciplinary Endocrine Weight Management clinic, in which we care for children with excessive weight gain and endocrine co-morbidities of their obesity.
