Research Interests

Dr. Gallias primary research interests are in the development of novel therapeutics against malignant brain and skull base tumors, outcomes following endonasal endoscopic skull base surgery and development of next generation intraoperative endoscopic platforms.


Dr. Gary Gallia's specialty is endoscopic endonasal surgical approaches to skull base pathologies with a focus on neurosurgical oncology. He utilizes the latest techniques in preoperative imaging, computer guided surgical navigation, intraoperative monitoring and minimally invasive and neuroendoscopic approaches in the management of patients with benign and malignant brain tumors, metastatic tumors to the brain, skull base neoplasms and pituitary tumors.

Dr. Gary Gallia graduated summa cum laude from the Gibbons Scholar MD/PhD program at Jefferson Medical College and Thomas Jefferson University. He completed his general surgery internship at The Johns Hopkins Hospital where he was awarded surgical intern of the year. He then completed his neurological surgery residency and a postdoctoral fellowship in neuro-oncology at The Johns Hopkins Hospital. Following residency, he completed a minimally invasive and endoscopic neurosurgery fellowship with Dr. Charles Teo at the Prince of Wales Private Hospital and Sydney Children's Hospital in Sydney, Australia.

    Research Summary

    Dr. Gallia is involved in screening pediatric glioblastomas for mutations in the PIK3CA gene and identifying and testing PIK3CA/Akt pathway inhibitors. Also, along with Dr. Siu, he has performed transcript profiling of glioblastoma stem-like cells to identify and subsequently analyze candidate marker genes.
