Dr. Scott M. Blackman is an assistant professor of pediatrics at the Johns Hopkins University School of Medicine. His areas of clinical expertise include pediatric endocrinology.

Dr. Blackman cares for infants and children with all types of endocrinologic disorders, including diabetes mellitus and disorders of growth, puberty, and the thyroid and pituitary glands. He has a special interest in atypical forms of diabetes, including diabetes associated with cystic fibrosis (CF). To improve the clinical care for people with endocrine complications of CF, he started a multidisciplinary clinic for pediatric patients with CF and cystic fibrosis-related diabetes (CFRD).

He completed his undergraduate studies at Princeton University and received his M.D. and Ph.D. degrees from the Vanderbilt University School of Medicine. He completed his internship and residency in pediatrics and fellowship in pediatric endocrinology at Johns Hopkins. Dr. Blackman has been a faculty member in pediatric endocrinology since completing his fellowship in 2007.

Dr. Blackman’s research interests include identifying genetic variants responsible for CFRD, which is seen commonly seen in teenagers and adults with cystic fibrosis. His long-term research goals include understanding molecular mechanisms of diabetes, such as type 1 and type 2 diabetes as well as CFRD.

He is a recipient of the 2014 Gilead Research Scholars Award for Cystic Fibrosis and has received awards from the Pediatric Endocrine Society and Cystic Fibrosis Foundation. He serves on the Program Planning Committee for the North American Cystic Fibrosis Conference and on the editorial board of the Journal of Cystic Fibrosis.

He serves on study sections for the NIH (NIDDK) and the Cystic Fibrosis Foundation.  He is a member of the Society for Pediatric Research and is a U.S. News Top Doctor. more

Research & Publications

Research Summary

Dr. Blackman’s primary research interest is in how gene variants cause diabetes and other metabolic diseases in people with cystic fibrosis (CF). His projects aim to determine how CFTR and other genes combine to cause cystic fibrosis-related diabetes (CFRD) and other complications of CF.
