b'2018-2019 YEAR BOOKTransitionsTrusteesIn May 2019 the Carnegie Board of Trustees unanimously elected Craig Barrett, former president65and chief executive officer of chip-maker Intel Corporation, as chairman of the Carnegie Board of Trustees. David Thompson, former president and chief executive officer of the global aerospace and defense company Orbital ATK, was unanimously elected as vice chair. They succeed outgoing cochairs Stephen P. A. Fodor, cofounder of the microarray technology company Affymetrix, and\x1f Craig BarrettSuzanne Nora Johnson, former vice chairman of Goldman Sachs, and outgoing vice chair, Bruce Ferguson, president of the American University of Iraq, Sulaimani.EmbryologyStaff associate Kamena Kostova joined the Department of Embryology in November 2018. She studies ribosomes, the factory-like structures inside cells that produce proteins, particularly the fundamental question of how cells respond when their ribosomes break down. She uses mass spectrometry, functional genomics methods, and CRISPR genome editing for this work. Kostova received a B.S. in biology from the Massachusetts Institute of Technology and a Ph.D. in biomedical\x1f David Thompsonsciences from the University of California, San Francisco. She was a recipient of a Fred Hutchinson Cancer Research Center 2018 Harold M. Weintraub Graduate Student Award.Geophysical LaboratoryStaff scientist Sally June Tracy joined Carnegie in early 2019. She studies how crystallizing materials behave in extreme environments to understand the fundamental physical behavior of materials under high-pressure and high-temperature conditions. Tracy uses dynamic compression techniques with high-energy X-ray sources at conditions that mimic impacts and the interiors of terrestrial and exoplanets. Tracy received her B.A. in physics from Occidental College and both a\x1f Kamena Kostovamasters and a Ph.D. in materials science from the California Institute of Technology. She was a postdoctoral scholar at Princeton University prior to Carnegie. Plant BiologyEvolutionary geneticist Moises Exposito-Alonso joined Carnegie as a staff associate in 2019. He investigates how plants will evolve to keep pace with climate change with large-scale ecological and genome-sequencing experiments and computational methods to forecast evolutionary outcomes of potential future biodiversity losses. He is also interested in developing genome\x1f Sally June Tracy engineering methods to help species adapt. Exposito-Alonso earned a B.S. in biology from the University of Seville, an MSc in quantitative and population genetics from the University of Edinburgh, and a Ph.D. in ecological genomics from the Max Planck Institute in Tbingen. He was also a postdoctoral fellow at the University of California, Berkeley.\x1f Moises Exposito-Alonso'
