Neurological Surgery


Professor of Neurosurgery and Oncology
Irving J. Sherman Research Professor



Dr. Riggins received his medical and Ph.D. degrees from Emory University, where he graduated from the Medical Scientist Training Program. He entered directly into a research fellowship in the Johns Hopkins Oncology Department.

Research Summary

Professor of Neurosurgery and Oncology at Johns Hopkins, Dr. Gregory Riggins directs the Brain Cancer Biology and Therapy Research Laboratory. The main goal of his research is to locate and evaluate molecular targets for new brain tumor therapies. A major component of this research is the location of new small molecules.

Dr. Riggins is the inaugural recipient of the Irving J. Sherman, M.D. Research Professorship in Neurosurgery Research. He is author of more than 6O research publications. He has worked with the Cancer Genome Anatomy Project to coordinate a large cancer gene expression database, SAGE Genie.
