Adam Riess is a Bloomberg Distinguished Professor, the Thomas J. Barber Professor in Space Studies at the Krieger School of Arts and Sciences, a distinguished astronomer at the Space Telescope Science Institute and a member of the National Academy of Sciences.
He received his bachelor's degree in physics from the Massachusetts Institute of Technology in 1992 and his PhD from Harvard University in 1996. His research involves measurements of the cosmological framework with supernovae (exploding stars) and Cepheids (pulsating stars). Currently, he leads the SHOES Team in efforts to improve the measurement of the Hubble Constant and the HIgher-z Team to find and measure the most distant type Ia supernovae known to probe the origin of cosmic acceleration.
In 2011, he was named a co-winner of the Nobel Prize in Physics and was awarded the Albert Einstein Medal for his leadership in the High-z Supernova Search Team's discovery that the expansion rate of the universe is accelerating, a phenomenon widely attributed to a mysterious, unexplained "dark energy" filling the universe. The discovery was named by Science magazine in 1998 as "the Breakthrough Discovery of the Year."
His accomplishments have been recognized with a number of other awards, including a MacArthur Fellowship in 2008, the Gruber Foundation Cosmology Prize in 2007 (shared), and the Shaw Prize in Astronomy in 2006.

Charles L. Bennett is Bloomberg Distinguished Professor, Alumni Centennial Professor, and a Johns Hopkins University Gilman Scholar in the Department of Physics and Astronomy with a joint appointment at the Applied Physics Laboratory. His major field of research is in experimental cosmology. In particular, he has contributed to the establishment of a standard model of cosmology, and currently engaged in testing and extending that model.
Bennett led the Wilkinson Microwave Anisotropy Probe (WMAP) mission. WMAP was competitively selected in 1996 as a NASA Explorer mission, launched in June 2001, and its first scientific results were issued in February 2003. WMAP quantified the age, content, history, and other key properties of the universe with unprecedented accuracy and precision. This was recognized by Science magazine as the 2003 "Breakthrough of the Year." The WMAP satellite ended its nine years of scientific observations in August 2010 and the full data analysis was published in 2013.
Previous to his work in WMAP, Bennett was the deputy P.I. of the Differential Microwave Radiometers (DMR) instrument and a member of the Science Team of the Cosmic Background Explorer (COBE) mission. The scientific results from this work included the first detection of variations across the sky of the temperature of the cosmic microwave background radiation. Currently, Bennett is working on a ground-based microwave telescope called the Cosmology Large Angular Scale Surveyor (CLASS) to make critical measurements of the history of the universe, including its first moments. He is also a member of the Euclid space mission consortium and the Subaru Prime Focus Spectrograph (PFS), aimed at measuring the properties of the dark universe: dark matter and dark energy.
Bennett has received several awards and honors, including the 2015 Caterina Tomassoni and Felice Pietro Chisesi Prize, the 2012 Gruber Cosmology Prize, the 2010 Shaw Prize in Astronomy, the 2009 Comstock Prize in Physics, the 2006 Harvey Prize, and the 2005 Henry Draper Medal. He twice received the NASA Exceptional Scientific Achievement Medal, once for COBE and once for WMAP. He also received the NASA Outstanding Leadership Medal for WMAP.
Bennett received his PhD in Physics from MIT in 1984 and his BS degree in Physics and Astronomy, cum laude with High Honors in Astronomy, from the University of Maryland, College Park in 1978. He was also a summer trainee Fellow of the Carnegie Institution of Washington, Department of Terrestrial Magnetism from 1976 to 1978. He joined the scientific staff of the NASA Goddard Space Flight Center in 1984 and later became the Infrared Astrophysics Branch Head, and then a Senior Scientist for Experimental Cosmology and a Goddard Senior Fellow. Bennett became a professor at the Homewood campus of the Johns Hopkins University in January 2005. Bennett is a member of the National Academy of Sciences, a Fellow of the American Association for the Advancement of Science (AAAS), a member of the American Academy of Arts and Sciences, and a Fellow of the American Physical Society (APS).

Francesca Serra joined the Physics and Astronomy department at Johns Hopkins University in 2016. She obtained her BA and Masters degree from the University of Parma (Italy) and her PhD from the University of Cambridge (UK). She was a postdoctoral researcher at the University of Milan (Italy) and at the University of Pennsylvania.
She is a soft matter experimentalist and her research is focused on liquid crystals. This phase of matter intermediate between liquid and solid is familiar to all of us for its use in liquid crystal displays. However, while liquid crystals in displays are usually "well-behaved" ordered fluids, interesting properties emerge when these materials are under confinement and forced to form topological defects. Francesca Serra is interested in studying liquid crystal topological defects in terms of their optical properties and their interaction with living cells.

Hal Weaver has been pursuing space-borne, rocket-borne, airborne, and ground-based investigations in planetary science since 1978. For his doctoral degree (Ph.D. in physics from The Johns Hopkins University in 1982), he performed the first systematic investigation of cometary ultraviolet (UV) emissions using the NASA/ESA International Ultraviolet Observer (IUE) satellite, providing circumstantial evidence that water was the dominant volatile constituent in cometary nuclei.
In 1985-1986 he made infrared (IR) observations of Comet Halley from the NASA Kuiper Airborne Observatory (KAO), which resulted in the first unambiguous, direct detection of water in comets, and for which he was awarded the NASA Medal for Exceptional Scientific Achievement in 1988. In 1996, asteroid 1984 FN was renamed to asteroid "Halweaver" in recognition of Weaver's work on the chemical composition of comets.
Weaver has led many investigations of comets using the Far Ultraviolet Spectroscopic Explorer (FUSE) and the NASA/ESA Hubble Space Telescope (HST). In March 2007, Weaver was appointed as a Co-Investigator on the Alice Ultraviolet Spectrograph, which is one of the principal NASA contributions to the ESA-led Rosetta comet mission.
Weaver joined the Senior Professional Staff at The Johns Hopkins University Applied Physics Laboratory in May 2002, and he has been a member of the Principal Professional Staff since 2006. He is currently the Project Scientist on the New Horizons Mission, which is the first spacecraft mission to Pluto and the Kuiper belt. In 2005, Weaver co-led a team that discovered two new satellites around Pluto (Nix and Hydra), and he was also on the team that discovered two other small Plutonian satellites, "P4" in 2011 and "P5" in 2012.

- Research in the Area of Theoretical Astrophysics, Particularly As It Applies to Active Galactic Nuclei, Black Holes, and High - Energy Astrophysics
Currently his work is focused on the physics of accretion disks, especially with a view toward linking the physics of MHD turbulence within these disks to the light they produce. To do this, he works with large-scale numerical simulation codes whose physics repertory includes the MHD equations in full general relativity and radiation diffusion (see picture below, illustrating magnetic field structure in matter accreting onto a spinning black hole). Using similar tools, he is also engaged in developing photon signals of gravitational wave sources like the merger of supermassive black holes, with the hope of enabling ordinary telescopes to identify examples of these events.
His book, Active Galactic Nuclei: From the Central Black Hole to the Galactic Environment, is the standard graduate-level textbook on quasars, radio galaxies, and related objects. Published by Princeton University Press in 1999, it is aimed at advanced graduate students and researchers in the field.
Julian H. Krolik conducts research in the area of theoretical astrophysics, particularly as it applies to active galactic nuclei, black holes, and high-energy astrophysics.
Research Interests: The X-ray background, hot ISM/IGM, X-ray instrumentation, solar wind charge-exchange, and various topics concerning the Earth's magnetosheath

Luciana Bianchi is a research professor in the Department of Physics and Astronomy of the Johns Hopkins University. She earned her PhD in astronomy (summa cum laude) from the University of Padua. Prior to joining the Johns Hopkins University in 1996, she held research positions at Italian institutes, the European Space Agency (Vilspa, Spain), and the Space Telescope Science Institute (Baltimore, MD).
She has authored more than 500 scientific publications, including invited papers and reviews.
She is a member of the International Astronomical Union (IAU), the American Astronomical Society (AAS), the European Astronomical Society (EAS), and the Sociedad Española de Astronomía (SEA). She has been serving in panels and committees for NASA, for the European Research Council, national space agencies and foundations, and in several international panels and forums.
Bianchi's research on massive stars, stellar populations, and star formation in nearby galaxies is pursued with observing programs using space-borne telescopes such as GALEX (UV), HST (UV to near-IR, including large treasury programs to characterize star-forming regions in galaxies of the Local Group), UVIT (UV), and large ground-based telescopes.
Bianchi was a co-investigator in NASA's GALEX mission, leading studies of nearby galaxies. She leads the "UV sky" project, which provides the first comprehensive view of the sky at ultraviolet (UV) wavelengths and the characterization of hundreds of millions astronomical sources from the GALEX sky surveys, with matched databases at longer wavelengths, as well as time-domain studies. One of the results is an unprecedented census and characterization of the elusive hot white dwarfs in the Milky Way, which prompted revisions of current Milky Way models, and large follow-up programs with HST.
She has been involved in development and testing of astronomical instrumentation, and has led or participated in design, development, and science operations of space-borne observatories from IUE to GALEX.

N. Peter Armitage has been at Johns Hopkins University since 2006. He received his B.S. in Physics from Rutgers University in 1994 and his PhD from Stanford University in 2002. He is a physicist whose research centers on material systems which exhibit coherent quantum effects at low temperatures, like superconductors and "quantum" magnetism. Dr. Armitage's principal scientific interest is understanding how is it that large ensembles of strongly interacting, but fundamentally simple particles like electrons in solids act collectively to exhibit complex emergent quantum phenomena. He is exploiting (and developing) recent technical breakthroughs using very low frequency microwave and THz range radiation to probe these systems at their natural frequency scales. The material systems of interest require novel measurement techniques as their relevant frequencies typically fall between the range of usual optical and electronic methods.
