Geoffrey S. F. Ling, M.D., Ph.D., is a medical doctor who retired from the United States Army as a Colonel. He served as the Director of the Defense Advanced Research Projects Agency (DARPA) Biological Technologies Office from 2014 until 2016. He is considered to be the "US Army's premier subject matter expert on traumatic brain injury (TBI)", and was for years the only neuro-intensive care specialist in the US military.

Prominent in his research portfolio are neuroscience, specifically, Preventing Violent Explosive Neuro Trauma (PREVENT), the prevention of traumatic brain injury, and development of responsive, brain-controlled, artificial arms. He also serves as the Deputy Director of the Defense Sciences Office. Ling is a recipient of the Humanitarian Award from the Brain Mapping Foundation.

Ling earned his BA with honors from Washington University, and earned his doctorate in pharmacology from Cornell University School of Medicine (1982). He completed post doctoral training in Neuropharmacology at the Sloan-Kettering Memorial Cancer Center (1982-1985). In 1989, Ling earned an M.D. from Georgetown University School of Medicine. Both his neurology internship (1989-1990) and later residency (1990-1993) were completed at Walter Reed Army Medical Center. From 1993-1995 Ling had a Fellowship at Johns Hopkins University, Neurosciences Critical Care Unit.

Ling completed two combat tours: Afghanistan (2003) and Iraq (2005), as well as four "Gray Team" tours to study combat brain injuries. His medical studies of the war in Afghanistan and Iraq show that over 50% of those who died of wounds had head injuries.

Prior to his position as Deputy Director at DARPA Ling was a tenured professor and Acting Chair of the Department of Neurology at the Uniformed Services University of the Health Sciences (USUHS). He worked at the USUHS from 1995-2012 and for many years was the Army's only neuro-intensive care physician. Ling is also an Adjunct Associate Professor of Neurology and Anesthesiology & Critical Care Medicine at Johns Hopkins Hospital and a member of the White House Office of Science and Technology Policy (OSTP). Ling served as an Army doctor for 27 years, and retired in 2012. Ling and his work have been featured twice on the TV show 60 Minutes, in 2009 and 2012.
