David J. Larson, director of scientific marketing for material analysis technology developer CAMECA Instruments Inc., has been appointed a fellow of the Microscopy Society of America (MSA). The MSA is a nonprofit organization dedicated to the promotion and advancement of techniques and applications of microscopy and microanalysis in all relevant scientific disciplines. Fellows have been conferred the MSA's Distinguished Scientist Award and are senior distinguished members of the organization, making significant contributions to the advancement of the field of microscopy and microanalysis through a combination of scientific achievement and service. The appointment is restricted annually to 0.5 percent of total MSA membership. Larson was selected for his “pioneering contributions to the development of atom probe science and technology, especially its application to complex materials systems, and for his many contributions to the Society.” Larson received his Ph.D. from the University of Wisconsin and is currently the president of the International Field Emission Society. Prior to joining CAMECA, he held staff positions at Seagate Technology and Oak Ridge National Laboratory and was a U.S. National Science Foundation International Research fellow at the University of Oxford. “I am very pleased and honored to be included in the list of scientists that the Microscopy Society of America has designated as fellows,” Larson said. “Since 1942, MSA has supported, promoted, and pioneered the development and application of microscopy. I am proud to have contributed to a very small part of that.” CAMECA is a manufacturer of scientific instruments for material micro- and nanoanalysis.
