Tel: +1 608 262 7964

I have redefined my mission in line with my interest in preserving the history, particularly in terms of conducting oral history interviews of early pioneers in EPMA and in the development of our society. I work closely with Mike Marko, who is the archivist of the Microscopy Society of America. We conduct oral history interviews of both pioneers as well as individuals who have made significant advances in our fields. These are archived and made available via MSA, though MAS ones will in the future be available via a link on the MAS website. I have interviewed over a dozen individuals, including several in France who worked Castaing, as well as Peter Duncumb in the UK. With assistance from the family of David Wittry, inventor of the ARL microprobe and a founder of Electron Probe Analysis Society of America (EPASA), the first name of our organization, I accessed his files which were in themselves an archive of EPMA in the 1950s. And I have been bequeathed by the previous archivists with some documents from the early years of the society, many of which have been scanned and will also be available online.

After dropping out of college at the height of ‘turbulent 60s’ and then spending many years as an arc-welder and union gadfly in a shipyard, John returned to school and become a geologist. By 1983, he had gotten his B.S. in Geology at the University of Maryland, and soon after was at Johns Hopkins, spending 2 field seasons in the Aleutians studying Shishaldin Volcano. Around 1985, he became acquainted with the MAC probe at the Geophysical Lab in DC, spending many nights straining his eyes trying to see the microscope’s image of the sample surface and punching commands on the teletype (“surely you jest”) and being warned by David George “do not touch the PHA dials”. He did a post-doc at the Smithsonian in 1989 studying anhydrite inclusions in the Nevado del Ruiz pumice, using the Smithsonian’s 9 spectrometer ARL-SEMQ under the eyes of Gene Jarosewich and Joe Nelen. He next analyzed anhydrite in Pinatubo pumice with the new Hopkins JEOL 8600, before being hired to run the probe lab at Wisconsin. There he babysat the ARL-SEMQ while waiting for a new CAMECA SX51 to come. He is now the proud father of a CAMECA SXFive FE. His oddest objects of study have been metal found in Oscar Meyer hot dogs and white crystals on cheese. He has 59 publications and 143 abstracts. He is also a historian, the archivist of MAS, and has been an amateur radio operator (WA3BTA) since 1964.

The purpose of the Strategic Planning Committee (SPC) is to coordinate with MAS council to identify key objectives that best fulfills the mission of the society, and to create long-term plans and action items that will achieve these objectives. Currently, there are two key objectives the SPC is focused on. These are: 1) to develop a sustainable solution for retaining and effectively utilizing institutional knowledge and 2) enhance membership retention and participation in society functions.

Vin is a Senior Scientist in the Functional Materials Organization at General Electric Global Research (GEGR) where he performs surface analysis to support research programs at GEGR, GE businesses, and strategic partners. Vin obtained a B.S. degree in chemistry from Marshall University in 1987 and a Ph.D. in physical chemistry (1994) from the University of Pittsburgh, under the guidance of Prof. John T. Yates, Jr. After completing his degree, Vin accepted a post-doctoral position at Argonne National Laboratory where he was part of a multi-laboratory team that designed, built, and tested a novel reflectron analyzer for real-time, in-situ, studies of surfaces during film growth at mTorr pressures using pulsed ion beam techniques – the work resulted in a 1997 R&D 100 Award. Currently. Vin’s research is focused on the applications of ToF-SIMS analysis, emphasizing how multivariate statistical analysis tools facilitate data reduction. Vin is also working with external laboratories in order to evaluate advanced microstructural characterization techniques such as Atom Probe Tomography and Helium Ion Microscopy and show the benefits these techniques have for industrial materials. Vin holds 6 U.S. patents, more than 90 publications in refereed journals, more than 140 GEGR internal manuscripts, numerous contributed and invited talks. Vin has co-authored 3 book chapters and edited one book “Surface Analysis and Techniques in Biology” (Springer, 2014). He serves as a mentor to many researchers.

The MAS Fellows Committee was established to recognize eminent scientists, engineers, and technologists in the field of microanalysis of materials and related phenomena to serve as ambassadors for the Society. Members of MAS who have distinguished themselves through outstanding research and service to the microanalysis community are eligible for this recognition. Relevant career pursuits include, but is not limited to, technique development, applications, theory development, and distinguished service to the society. The MAS Fellows Committee has created a process for soliciting and judging nominations on an annual basis. Election as a MAS Fellow will be highly selective but should represent a broad cross-section of the MAS membership.

He has published over 250 papers and 17 patents in these fields in that time. Tom has driven innovation in instrumentation for atom probe tomography over the past two decades. He continues to pursue microscopy innovations such as atomic-scale tomography by developing new detector technologies and combining atom probe tomography with electron microscopy in a single instrument. Tom was a member of the Executive Council of the Microscopy Society of America (MSA) from 2000 to 2002 and the International Steering Committee of the International Field Emission Society (IFES) from 2002 to 2008.
