N. JEREMY KASDIN is the assistant dean for engineering programs at the University of San Francisco. He is also the Eugene Higgins Professor of Mechanical and Aerospace Engineering, emeritus, at Princeton University. Previously, he was a member of the Princeton faculty for 20 years and held the post of vice dean of the School of Engineering and Applied Science. Prior to that, he was the chief systems engineer for NASA’s Gravity Probe B spacecraft. While at Princeton he studied techniques for high-contrast imaging from ground and space using coronagraphs and starshades. He was the principal investigator for the Coronagraphic High Angular Resolution Imaging Spectrograph (CHARIS) instrument on the Subaru Telescope on Maunakea, HI. He is the adjutant scientist for the coronagraph instrument on NASA’s Wide Field Infrared Survey Telescope. He earned his Ph.D. in aeronautics and astronautics from Stanford University. He has previously served on National Academies committee, including the Astro2010 Panel on Particle Astrophysics and Gravitation.
DAVID B. KIEDA is a professor at the University of Utah (UU) in the Department of Physics and Astronomy. He also serves as the dean of the UU Graduate School. Kieda is the head of the UU experimental gamma-ray astronomy research group. He has led the development of new technologies for observational high-energy astrophysics, including work on the Fly’s Eye/High-Resolution Fly’s Eye, the Very Energetic Radiation Imaging Telescope Array System (VERITAS), HAWC, and the Cherenkov Telescope Array (CTA) observatories. Kieda also works on the development of techniques for visible band imaging of nearby hot stars with an angular resolution better than 100 micro-arc seconds. He received the Utah Governor’s Medal of Science and Technology and is a fellow of the American Physical Society. He earned his Ph.D. in physics from the University of Pennsylvania. He has not previously served on an Academies’ committee.
ANDREA N. LOMMEN is a professor and the chair of the Physics and Astronomy Department at Haverford College. Previously she held the same positions at Franklin and Marshall College. Dr. Lommen has founded efforts in gravitational wave detection using pulsars through both the North American Nanohertz Observatory of Gravitational Waves and the International Pulsar Timing Array. She is currently leading efforts to demonstrate pulsar timing capabilities in the x-ray regime as part of NASA’s Neutron Star Interior Composition Explorer. She has received a National Science Foundation CAREER award. She received a Ph.D. in astrophysics from the University of California, Berkeley. She has not previously served on an Academies’ committee.
BRIAN D. METZGER is an associate professor at Columbia University in the Department of Physics. His research covers a wide range of topics in theoretical high energy astrophysics, mostly related to compact objects, nucleosynthesis (astrophysical origin of the elements), and the electromagnetic counterparts of gravitational wave sources. Dr. Metzger has received a New Horizons Breakthrough Prize in Physics and a Bruno Rossi Prize of the American Astronomical Society. He earned his Ph.D. in physics from the University of California, Berkeley. He has not previously served on an Academies’ committee.
JAMES H. YECK is a researcher with the University of Wisconsin, Madison. He serves as the interim project director for the Cosmic Microwave Background-Stage 4 (CMB-S4) project. Previously he was the director general of the European Spallation Source (ESS) in Lund, Sweden, and the project director of the IceCube South Pole Neutrino Observatory. He has more than 30 years of project director and project manager experience leading projects in both federal and contractor roles. He currently chairs and serves as a member of numerous advisory committees for projects and facilities sponsored by the Department of Energy and National Science Foundation, including LIGO and the Large Synoptic Survey Telescope. He holds an M.S. in mechanical and nuclear engineering from Northwestern University. He has not previously served on an Academies’ committee.
NICOLAS YUNES is a professor of physics at the University of Illinois at Urbana-Champaign. Previously he was an associate professor of physics and one of the founding directors of the eXtreme Gravity Institute at Montana State University. Key areas of research have included gravitational wave theory, modeling and data analysis with ground- and space-based detectors, black hole and neutron star theory, and tests of general relativity with gravitational waves, binary pulsars, and solar system observations. He has received the Young Scientist Prize of the International Union of Pure and Applied Physics and the International Society on General Relativity and Gravitation, the NASA Einstein Fellowship, and the Juergen Ehlers Thesis Prize from the International Society on General Relativity and Gravitation. He is an editor of Classical and Quantum Gravity. He received a Ph.D. in physics from the Pennsylvania State University. He has not previously served on an Academies’ committee.
