Ravindra Ajith DeSilva, Ph.D.
Instructor of Radiology and Radiological Science
Dr. Ravindra De Silva is an Instructor in the Johns Hopkins Medicine Department of Radiology and Radiological Science and a member of the Johns Hopkins Bayview Medical Center. He specializes in molecular imaging, carbohydrate chemistry, small molecule synthesis and clinical development and manufacturing of imaging and therapeutic agents.
Dr. De Silva received a B.S. chemistry special degree from University of Peradeniya Sri Lanka, and M.Sc. in Inorganic chemistry from National University of Singapore, Singapore. In 2009 he received a Ph.D. in Organic Chemistry from Wayne State University in Detroit, Michigan.
Before joining Johns Hopkins faculty, he worked an Instructor/ Assistant lab-director at C-TRIC facility University of Colorado Denver, where he was responsible for all clinical development and manufacturing of radiopharmaceuticals for clinically relevant disorders.
As Radiochemistry Director at the Center for Translational Molecular Imaging (CTMI), Johns Hopkins Bayview Medical Center, Dr. De Silva is responsible for clinical development and manufacturing of new imaging and therapeutic agents discovered by Johns Hopkins Scientists and their collaborators. CTMI is the first Academic Research Organization (ARO) created for development of novel radiopharmaceuticals that make possible the vision of individualize medicine.
