In the relative quiet of the Central Identification Laboratory, Holland holds the awesome responsibility for approving the identifications of all U.S. military personnel from past military conflicts. During his tenure this has included over 1000 soldiers from World War I, World War II, the Korean War, the Cold War, and the Vietnam War -- including the Vietnam Unknown Soldier from Arlington National Cemetery.
Holland received a bachelor's degree in fine art from the University of Missouri and a Master's degree and a Doctorate degree in anthropology from the same institution. He worked as an archaeologist and museum curator before taking a position with the Department of Defense. He is one of less than 80 Diplomates of the American Board of Forensic Anthropology, is a Fellow of the American Academy of Forensic Sciences, a member of the American Society of Crime Laboratory Directors, a member of the Council of Federal Forensic Laboratory Directors, and a consultant to the New York State Police. He routinely briefs high-ranking military and government officials including the secretaries of State and Defense, and has served in scientific advisory roles to the National Institute of Justice and the International Commission on Missing Persons.
Holland and his laboratory are frequently featured on such programs as Discovery, Nightline, 60 Minutes, National Public Radio, and Nova.
