    Travis Tierney is a pediatric functional neurosurgeon who recently completed fellowship training at Nicklaus Children’s Hospital in Miami. He graduated from Johns Hopkins in 2003 and stayed on for the Halsted Internship in General Surgery before finishing his residency training in Neurosurgery at Massachusetts General Hospital. In 2011, he completed a fellowship in Stereotactic and Functional Neurosurgery with Dr. Andres Lozano at the University of Toronto. That same year, he joined the Brigham and Women's Hospital faculty as Director of Stereotactic and Functional Neurosurgery, where he was site PI for the essential tremor study. Dr. Tierney’s research background includes expertise in neuron survival during brain development, local drug delivery, cell and gene therapies, and neuromodulation. His current clinical interests include childhood neuropsychiatric disease, movement disorders, and epilepsy. His current clinical research focuses on minimally invasive surgery for pediatric epilepsy, including laser interstitial thermal therapy (LITT) and MR-guided Focused Ultrasound (MRgFUS).

    Dr. Elias served as the Principal Investigator for this international, randomized, controlled trial of focused ultrasound thalamotomy to treat essential tremor. He is a Professor of Neurological Surgery and Neurology at the University of Virginia, and serves as the Director for Stereotactic and Functional Neurosurgery. His clinical research involves the use of MR Guided Focused Ultrasound for the treatment of movement disorders like essential tremor and Parkinson’s disease. His team successfully treated the first essential tremor patient with focused ultrasound thalamotomy in February of 2011. Since then, several clinical trials have demonstrated the feasibility of successfully delivering acoustic energy through the intact scalp and skull. Other research interests include laser interstitial thermal therapy and image- guided deep brain stimulation. In the laboratory, he is studying the use of focused ultrasound to reversibly modulate the central nervous system for non-invasive brain mapping. Academically, Dr. Elias serves on the Editorial Board of the Journal of Neurosurgery and holds the rank of Professor with Tenure in the School of Medicine. He serves on the Advisory Board for the International Essential Tremor Foundation.

    Dr. Pejman Ghanouni is an Assistant Professor of Radiology at the Stanford University Medical Center. Dr. Ghanouni’s clinical and research focus is on the development of clinical applications of MR guided focused ultrasound. In 2016, he was named by the Focused Ultrasound Foundation as a co-Director of the Stanford Focused Ultrasound Center of Excellence. He has treated over 100 patients with this technology, and uses MRgFUS to treat patients with uterine fibroids, painful bone tumors, soft tissue tumors, and prostate cancer. In collaboration with Drs. Casey Halpern and Jaimie Henderson of Neurosurgery, Dr. Veronica Santini of Neurology, and Dr. Kim Butts Pauly of Radiology, he also uses MRgFUS to treat patients with Essential Tremor.
