Ryna Beth Marinenko

In 1972 Ryna Marinenko began working at the National Bureau of Standards (now NIST) and in 1974 she joined the Microanalysis Section in 1974 she (now the Microanalysis Research Group) where she is a Senior Scientist.   Her work and research interests on qualitative and quantitative WDS and EDS x-ray microanalysis with the electron microprobe has concentrated on the certification of standards for microanalysis and the development of digital wavelength dispersive compositional mapping for which she received the NIST Bronze Medal in 1988 and shared an IR-100 award in 1987 for the latter.  Microanalysis standards certified under her leadership include multielement bulk alloys and glasses as well as glass microspheres.  Related projects include the micro-characterization (for composition, heterogeneity, and thickness) of high technology materials such as bulk high-temperature superconductors, thin films used in opto-electronic devices, and bulk and thin film ferroelectric ceramics.  She is a member of the Sigma-Xi, and MAS (Microbeam Analysis Society), and is an active member of the latter organization in which she served as a Director and President, and presently writes the newsletter.  She is also the US TAG (Technical Advisory Group) chairman for the ISO TC 202 (International Standards Organization Technical Committee 202) for Microbeam Analysis.
