Elvira Isganaitis's clinical interests include pediatric diabetes (type 1, type 2 and monogenic), the prevention of childhood obesity and diabetes, and general pediatric endocrinology. She received her MD degree from McGill University in Montreal, after which she obtained a Master's in Public Health at the Harvard School of Public Health, followed by residency training in general pediatrics at University of California San Francisco (UCSF) and a subspecialty fellowship in pediatric endocrinology at Massachusetts General Hospital.

Dr. Isganaitis' overarching career goal is the prevention of childhood obesity and diabetes and their complications. She is particularly interested in the role of early life risk factors such as maternal and paternal obesity, birth weight, and postnatal nutrition as contributors to childhood obesity. Her research uses novel “-omics” platforms such as transcriptomics, metabolomics and inaccessible human tissues such as umbilical cord blood, breast milk, and placenta to discover the mechanisms by which early life exposures contribute to future metabolic disease.

She currently divides her time between patient care in the Joslin Pediatric Clinic, basic research on cellular and epigenetic mechanisms of developmental programming and clinical trials for type 1 and type 2 diabetes in youth.
