Executive Board


Mark Devlin (Spokesperson)

Mark Devlin (Spokesperson) is the Reese W. Flower Professor of Astronomy and Astrophysics at the University of Pennsylvania. He received his Ph.D. from the University of California at Berkeley in 1993 and his B.A. in Physics and Math from the University of Wisconsin – Madison in 1988. His research is primarily in the area of cosmology and the evolution of structure in the universe as well as extra-galactic and galactic star formation. To further this work, his group at the University of Pennsylvania specializes in the design and construction of novel telescopes and cryogenic receivers operating at millimeter and sub-millimeter wavelengths. He is the currently the Co-Director of the Atacama Cosmology Telescope – ACT (NSF), the PI for the Balloon-borne Large Aperture Telescope – BLAST (NASA), and the PI of the MUSTANG instrument in the Green Bank Telescope (NSF). He is a fellow of the American Physical Society and currently sits on NASA’s Astrophysics Sub-Committee. |


Brian Keating (Simons Observatory Director)

Brian Keating is an astrophysicist with the University of California, San Diego’s Department of Physics and the Center for Astrophysics and Space Sciences. He and his team of 15 undergraduates, graduate students, and postdocs develop sensitive instrumentation to study the early universe in the radio-, microwave- and infrared-wavelength regimes of the electromagnetic spectrum. He is the author of nearly 100 scientific publications and holds two U.S. Patents. Professor Keating received his B.S. from Case Western Reserve University and his Ph.D. from Brown University in 2000. Later, he did his postdoctoral research at Stanford University and was an NSF Postdoctoral Fellow at Caltech before coming to UCSD in 2004. In 2007 he received the Presidential Early Career Award for Scientists and Engineers at the White House from President George W. Bush for his work on a telescope he c0-invented and fielded at the US Amundsen-Scott South Pole Research Station called “BICEP”. Presently, Professor Keating is one of the leaders of a collaboration operating two observatories in the Atacama Desert of Chile called POLARBEAR and the Simons Array. He is a member of the Board of Trustees for the National Museum of Mathematics (MoMath), the San Diego Air & Space Museum, Math for America, San Diego and the Arthur C. Clarke Center for Human Imagination. Dr. Keating is also a licensed commercial pilot with single-engine, multi-engine, turbine and instrument ratings. He is honored to transport patients in-need as a Command Pilot for Angel Flight West.


Kam Arnold

Kam Arnold is an Assistant Professor of Physics at the University of California, San Diego. Prior to that, Professor Arnold was the project manager and a co-investigator on the Simons Array project, the cutting-edge cosmic microwave background (CMB) polarization experiment currently deploying to the Chilean Atacama Desert. Professor Arnold received his Ph.D. at the University of California, Berkeley working on the pre-cursor to the Simons Array – POLARBEAR – which produced the first non-zero measurement of B-mode polarization in the CMB using CMB data alone.


Akito Kusaka

Akito Kusaka is a Divisional Fellow in the Physics Division at the Lawrence Berkeley National Laboratory (LBNL). His interest is in observational cosmology, in particular the measurement of cosmic microwave background (CMB) polarization. His present research includes technology development for the next generation Stage-4 CMB experiment and participation to ongoing Stage-3 experiments. He has been a member of the management team of POLARBEAR / Simons Array collaboration since 2014, when he took his current position at LBNL. He was previously a postdoctoral fellow at Princeton University and at the University of Chicago, working on ABS and QUIET CMB experiments. He received his Ph.D. in physics from the University of Tokyo in 2007, on the measurement of the CP violation in B meson system at Belle experiment.


Adrian Lee

Adrian Lee is a Professor of Physics at University of California, Berkeley. He received his Ph.D. from the Stanford University, where he worked development of techniques to directly detect Dark Matter particles. His current research is in measurements of the 2.7 K Cosmic Microwave Background. He participated in the MAXIMA experiment which was one of the first experiments to show that the geometry of the space in the universe is Euclidean and to confirm the presence of Dark Energy in the universe when its data was combined with data from other experiments. He has played a pioneering role in the use of superconducting transition-edge sensors (TES) as bolometers and the development of absorber-coupled and planar-antenna-coupled focal-plane arrays using that technology. He is NSF Principal Investigator of the POLARBEAR and Simons Array experiments in Chile which measure polarized fluctuations in the Cosmic Microwave Background, with the goals of characterizing gravitational lensing of the fluctuations and to search for a signal from inflation which is a hypothesized to occur a small fraction of a second after the Big Bang.


Lyman Page

Lyman Page has made measurements of the CMB temperature anisotropy and, more recently, polarization for thirty years. Data from his thesis experiment confirmed the DMR discovery of the anisotropy. Since then he has led or co-led half a dozen different CMB experiments. He was a founding member of the Wilkinson Microwave Anisotropy Probe and the founding director of the Atacama Cosmology Telescope project. Using a wide variety of techniques, he has made measurements from the South Pole, Saskatoon, and Cerro Toco Chile, and used balloon and satellite platforms. He has won a number of awards and is a member of the National Academy of Sciences. He is the Chair and James S. McDonnell Distinguished University Professor of Physics at Princeton University.


David Spergel

David Spergel is the Charles Young Professor of Astronomy on the Class of 1897 Foundation and Chair of the Department of Astrophysical Sciences at Princeton University. After September 2016, he will be the Founding Director of the The Flatiron Institute’s Center for Computational Astrophysics. Spergel was a member of the WMAP science team and the lead author of the most cited paper in physics in the new Millennium which described the cosmology based on its results. Spergel is a MacArthur Fellow, a Fellow of the APS, and a member of both the National Academy of Sciences and the American Academy of Arts and Sciences. Spergel shared the Gruber Prize, the Heinemann Prize, and the Shaw Prize for his work on cosmology. Spergel is currently chair of the NAS Space Studies Board, a member of the NASA Advisory Council, and co-chair of the WFIRST science team.


Suzanne Staggs

Suzanne Staggs received her PhD in physics from Princeton University in 1993, and her B.A. in physics from Rice University in 1987. After two years as a Hubble Fellow at the University of Chicago, she joined the faculty at Princeton, where she is currently the Henry deWolf Smyth Professor of Physics. She is currently on the AAAC, a fellow of the APS, and the PI of Advanced ACTPol. Her research focus is the experimental study of the cosmic microwave background (CMB) radiation, including precise measurements of its electromagnetic spectrum and thus its blackbody temperature, and exploration of its polarization properties and fine-scale angular anisotropies. Her present CMB work focuses on searching for the signature in the CMB polarization of gravity waves from an inflationary epoch in the primordial universe, and in using the CMB as a backlight to probe the growth of gravitationally-bound structures in the last thirteen billion years. This growth depends on such fundamental quantities as the nature of dark energy, and the mass of the neutrino.
