Christopher C. Joyner, 63, a Georgetown University professor of international law and director of the university’s Institute for Law, Science and Global Security, died Sept. 10 at Virginia Hospital Center in Arlington after complications from abdominal surgery.

The death was confirmed by his wife, Nancy Joyner.

Dr. Joyner joined the Georgetown faculty in 1994 and co-founded the Institute for Law, Science and Global Security in 2003.

In addition to hundreds of scholarly articles, he wrote or edited several books on subjects including the law of the sea, human rights and terrorism, and he was an expert on Antarctica and the law of the sea. Dr. Joyner was an officer in many professional organizations and committees in his field.

In January, he was a recipient of the Georgetown University Alumni Association’s Faculty Recognition Award. The citation noted his work as a lecturer for the university’s Travel Society, his participation in alumni voyages and his direction of the graduate program on international law and security in Florence, Italy. It also noted his attendance at Georgetown’s women’s soccer, lacrosse and basketball games.

Christopher Clayton Joyner, an Annandale resident, was a native of Aberdeen Proving Ground, Md., where his father was stationed in the Army.

He was a 1970 international affairs and history graduate of Florida State University, where he also received a master’s degree in international affairs in 1972 and a master’s degree in government in 1973. He completed a doctorate in foreign affairs from the University of Virginia in 1977.

Before joining the Georgetown faculty, Dr. Joyner taught at George Washington University, the University of Virginia, Dartmouth College and Muhlenberg College in Allentown, Pa.

He also served as a senior research fellow with the Woods Hole Oceanographic Institution in Massachusetts and what is now the Institute for Marine and Antarctic Studies at the University of Tasmania in Australia.

Survivors include his wife of 38 years, Nancy Douglas Joyner of Annandale; and two children, Kristin E. Joyner of Apopka, Fla., and Clayton D. Joyner of Annandale.
