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

Associate Professor of Pediatrics

Currently seeking M.S. students

I am an Associate 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 as well as gaining insights into Health Disparities witihin our populations.. The majority of my research and presentations have focused on improving the screening, diagnosis, and management of CFRD. For the past 10 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 recently completed a KL2 research grant and I am involved in a multi-center research grant that collaborates in recruiting and treatment of patients with CF-related diabetes issues.  I have varied research interests that will garner future research support.  My upcoming project will be with the Jaeb Health and Research Foundation in conjunction with the Cystic Fibrosis Foundation to conduct resarch for  the Cystic Fibrosis Bionic Pancreas.
