Dr. Brian Justus, a research scientist in the Optical Sciences Division of the Naval Research Laboratory (NRL), has been elected a Fellow of the Optical Society of America (OSA). He is recognized for experimental discoveries leading to the development of new optical materials and optical methods for the detection of ionizing radiation.

According to Elizabeth Rogan, OSA's executive director, "The distinction of fellows at OSA is reserved for those members of the optics and photonics community who are at the top of the profession. Dr. Justus fit this distinction and has offered valuable insights and contributions to the ongoing understanding of optical science." OSA Fellows are selected on a variety of criteria such as record of publications related to optics, service to OSA, achievements in optics or management ability. The number of fellows is limited by the bylaws to 10 percent of the total membership.

Dr. Thomas Giallorenzi, former superintendent of the Optical Sciences Division, explained that, "Dr. Justus's current research in the development of new optical materials that are used for the detection of ionizing radiation recently led to a breakthrough in the field of optical fiber scintillation dosimetry. Many groups have worked for years to develop an optical fiber dosimeter that could be used to verify the radiation dose a cancer patient receives during an external beam radiotherapy treatment. All previous efforts failed, primarily due to an inability to eliminate Cerenkov radiation in the optical fibers when they are exposed to high-energy radiation. Dr. Justus developed a novel, doped fuse quartz phosphor that possesses properties ideally suited for time-gated detection of the luminescence signals measured during the radiotherapy treatment. His approach effectively eliminated the Cerenkov interference and removed the final obstacle to development of a commercially viable optical fiber dosimeter system. The doped fused quartz phosphors, and the gated optical fiber dosimeter system that he developed, were patented and recently licensed. The system is currently under commercial development."

Dr. Justus received his B.S., M.S. and Ph.D. degrees in physical chemistry from the University of California, Riverside, CA, in 1977, 1979 and 1983, respectively. He came to NRL in 1983 as an NRC/NRL postdoctoral associate in the Optical Sciences Division. Dr. Justus became a permanent staff member of the division as a research scientist in 1985. He served as Head of the Quantum Electronics Section from 1998 to 2006 and was recently selected to his present position as Head of the Optical Physics Branch.

He is a member of the Optical Society of America and served as a Topical Editor in the area of General Optics for the OSA's premiere journal, Optics Letters, from 2002 to the present.

Dr. Justus received numerous awards while at NRL. These include: the NRL Alan Berman Research Publication Award (1992, 1995, 1996 and 2005); Thomas Edison Patent Award (1996 and 1997); and the NRL Technology Transfer Award (1997 and 2005). Dr. Justus has written over 50 scientific papers published in refereed journals and co-authored three book chapters. Dr. Justus holds over 20 patents with five recently licensed by the commercial community and generating income for NRL.
