Kalil G. Abdullah, M.D., MSc is an Assistant Professor in the Department of Neurological Surgery at UT Southwestern Medical Center.

He specializes in the treatment of adult brain tumors. 

Dr. Abdullah treats brain tumors using traditional microsurgery techniques and awake craniotomies to map intricate regions of the brain during surgery. He also uses endoscopic, tubular, and laser therapy to provide minimally invasive surgery options to his patients. He performs some of these surgeries using an intraoperative MRI scanner which allows him to see tumor resection in real time. He also performs fluorescence-guided tumor resections, and led the surgical team that performed the first such surgery in North Texas.

Dr. Abdullah earned his medical degree at the Cleveland Clinic Lerner College of Medicine, where he was a National Institutes of Health Howard Hughes Medical Institute Scholar. He completed a residency in neurological surgery at the University of Pennsylvania and then received advanced training in open and endoscopic neurosurgical oncology through a fellowship at the Wellington Hospital in New Zealand. He completed an additional research fellowship in stem cell biology and bioengineering at the University of Pennsylvania. He also holds a master’s degree in health economics and policy from the London School of Economics.

Dr. Abdullah directs an Integrated Brain Tumor Research Program that takes tumor tissue directly from the operating room to the laboratory to develop new drug and treatment targets. He is actively involved in both running and enrolling patients in clinical trials for brain tumors. 

He has published more than 100 research papers and has been an invited lecturer both nationally and internationally. He co-edited the seminal textbook on malignant gliomas, Glioblastoma
