Personal History:

Assistant Professor of Neurosurgery, Anatomy and Neurobiology at the University of Maryland School of Medicine, Dr. Woodworth received his B.S. in Chemistry from Tufts University, M.D. from Johns Hopkins University, and completed his residency in neurosurgery at Johns Hopkins. Dr. Woodworth received additional fellowship training in Nanomedicine (Johns Hopkins) and Neuro-endoscopy (Cornell NYPH). Dr. Woodworth is the Director of Neurosurgical Oncology, and an active member of the UM Greenebaum Cancer Center. He specializes in the treatment of patients with benign and malignant tumors of the brain and spine.

Research Interests:

As Director of the Department's Translational Research Laboratory, Dr. Woodworth studies and develops advanced drug and gene delivery systems for brain cancer. A long-standing problem in the treatment of glioblastoma, the most common and deadly primary brain cancer, is delivery of therapeutics to invading tumor cells. Systemically administered therapies reach these cells in low concentrations due in part to the intact blood brain barrier (BBB), and in part due to their far distance from the main or resectable tumor mass in functioning brain tissue. Therefore, effective delivery to the invading cancer cells, in particular modulation of genes and cellular pathways responsible for the disease pathogenesis, represents a promising therapeutic approach. To address these challenges, Dr. Woodworth investigates the delivery of therapeutic nanoparticles and drug formulations augmented by MR-guided focused ultrasound (MRgFUS) and convection enhanced delivery (CED). The laboratory also collaborates with leading brain cancer researchers to test these therapies in the most advanced and relevant brain cancer models. These approaches are anticipated to provide safe methods to achieve sustained therapeutic delivery, while achieving targeting efficiency beyond what can be realized with standard, often more complex strategies. In addition, it is envisioned that such delivery systems could be broadly used to treat a variety of brain disorders.
