From Wikipedia, the free encyclopedia

Rory Murphy (also published as Rory K. J. Murphy) is an Irish neurosurgeon and associate professor in the Department of Neurosurgery at Barrow Neurological Institute in Phoenix, Arizona. Murphy was a co-first author of a 2016 Nature paper focused on bioresorbable electronic brain sensors. He also worked as an investigator at Barrow for Neuralink's PRIME brain-computer interface clinical trial.[1][2][3]

Education

[edit]

Murphy received his medical degree from University College Cork in Ireland. He completed a neurosurgery residency at Barnes-Jewish Hospital, affiliated with Washington University in St. Louis. From 2016 to 2017, he completed a clinical fellowship in functional neurosurgery at the University of California, San Francisco.[1]

Career

[edit]

At Barrow Neurological Institute, Murphy serves as an associate professor in the Department of Neurosurgery. His clinical work focuses on complex cranial and spinal conditions, including tumors and spinal cord compression, along with peripheral nerve surgery. He holds board certification from the American Board of Neurological Surgery. His professional memberships include the American Association of Neurological Surgeons, AO Spine, the Congress of Neurological Surgeons, and the Cervical Spine Research Society Education Committee.[1]

Murphy serves as the site principal investigator for the U.S. Department of Defense's Cervical Spinal Cord Injury Trial. Earlier in his career, he served as a principal investigator for the Missouri Spinal Cord Injury Research Program.[1][4]

[edit]

In April 2024, Barrow Neurological Institute became the inaugural clinical trial site for Neuralink's PRIME Study. The study examines a brain-computer interface implant in patients with quadriplegia caused by cervical spinal cord injury or amyotrophic lateral sclerosis, also known as ALS.[3]

Murphy worked as an investigator on the study at Barrow. Coverage of the study's launch quoted Murphy describing the implant's goal as creating "a digital bridge between the brain and spinal cord" for patients with severe spinal cord injuries.[3]

Research

[edit]

Murphy shares co-first authorship with Seung-Kyun Kang, Suk-Won Hwang, and Seung Min Lee on "Bioresorbable silicon electronic sensors for the brain," published in Nature in 2016. The researchers described dissolvable, implantable silicon sensors designed to monitor intracranial pressure and temperature. After completing their purpose, the sensors safely resorb into the body, removing the need for surgical removal. By 2026, Google Scholar listed more than 1,100 citations for the paper.[2][5]

The research also received attention from the popular press. In January 2016, The Atlantic published an article centered on Murphy's work developing the sensors while practicing as a neurosurgeon. The article quoted Murphy on the day-to-day urgency involved in treating traumatic brain injuries. Murphy said, "I just took out a bullet from the back of a guy's head an hour ago."[6]

Wired also identified Murphy as a neurosurgeon working in brain-computer interface research in a 2026 article covering the field.[7]

Murphy's wider research record includes work on cervical spondylotic myelopathy, meningioma treatment outcomes, traumatic spinal cord injury, and peripheral nerve repair. His research has appeared in publications including the Journal of Neurosurgery, Neurosurgery, and Spine. As of 2026, Google Scholar reported more than 2,500 combined citations across his publications and an h-index of 22.[1][5]

Patents and industry work

[edit]

Murphy is named as a co-inventor on several U.S. patents involving implantable medical devices. These patents include systems designed to dynamically stimulate bone growth and electrical implant devices intended to increase patient compliance. Murphy is also a co-founder of the medical device company Intelligent Implants.[8][9]
