David S Simons

Scientist Emeritus

David Simons is a physicist in the Materials Measurement Science Division at the National Institute of Standards and Technology in Gaithersburg, Maryland. He received his undergraduate education at the Carnegie Institute of Technology and his Ph.D. in solid state physics from the University of Illinois. After a postdoctoral appointment at the University of Illinois he served as a chemist in the mass spectrometry group at the Knolls Atomic Power Laboratory in Schenectady, New York for three years before moving to the National Bureau of Standards (now NIST) in 1979. During his career Dr. Simons has specialized in the applications of secondary ion mass spectrometry to microelectronics and to nuclear forensics. He currently serves as a consultant to the International Atomic Energy Agency and to the Department of Energy's National Nuclear Security Administration.  He was a NIST Fellow and is a Fellow of AVS-The Science and Technology Society.  He has served as the co-chair of the Fifth International Conference on Secondary Ion Mass Spectrometry and of the AVS Topical Conferences on Quantitative Surface Analysis.
