Dimitrios A. Papaconstantopoulos was born in Athens, Greece, and graduated from the University of Athens with a B.S. degree in physics in 1961. He received a Ph.D. in theoretical solid state physics from the University of London, England, in 1966. He was a professor of physics at George Mason University from 1967 to 1977 and chairman of the physics department from 1974 to 1977. He is currently Head of the Complex Systems Theory Branch at the Naval Research Laboratory and Adjunct Professor of Computational Science at George Mason University. His areas of expertise include band structure calculations, superconductivity, and theory of alloys. He has authored 160 journal articles and 2 books and has given more than 200 presentations at professional meetings. He has won three Alan Berman Research Publication awards at NRL and the 1990 Sigma Xi Pure Science Award. He has been a Fellow of the American Physical Society since 1981.
