He graduated from PhysMath School in Yerevan in 1993, after which he studied physics at MIT. After completing his Ph.D. in experimental nuclear physics in 2006 at the University of Illinois at Urbana-Champaign, Mr. Danagoulian moved to Los Alamos National Laboratory, where he worked on a variety of research programs including stockpile stewardship, physics beyond the standard model, and nuclear security. He then worked for six years in industry, developing an award-winning active interrogation system that uses fast neutrons to detect fissionable materials, such as uranium and plutonium, hidden in cargo containers. In addition to treaty verification technologies, Mr. Danagoulian’s research interests include advanced methods for screening of commercial cargoes for the presence of nuclear materials.
