Maria S. (Sukie) Rayas, M.D.

Assistant Professor of Pediatrics

I am an assistant professor in the division of pediatric endocrinology and diabetes. My interests include learning about cystic fibrosis-related diabetes (CFRD) and other CF endocrine related disorders. The majority of my research and presentations have focused on improving the screening, diagnosis, and management of CFRD. For the past 7 years, I have helped develop a multidisciplinary clinic for CFRD patients in the CF Center with the CF center director and staff. I am now also the endocrinologist dedicated to seeing the adult CF patients with endocrine disorders.  I have a KL2 research grant and a multi-center research grant that collaborates in recruiting and treatment of patients with CF-related diabetes issues.
