Adam Riess

(JHU/STScI)

Dr. Adam Riess is an Astronomer at the Space Telescope Science Institute and a Professor at the Johns Hopkins University in Baltimore, MD. Dr. Riess received his B.S. in physics from the Massachusetts Institute of Technology in 1992 where he was inducted into the Phi Beta Kappa Society. He received his Ph.D. from Harvard University in 1996. Between 1996 and 1999

Dr. Riess was a Miller Fellow at the University of California at Berkeley. He joined the faculty of Space Telescope Science Institute in 1999. In 1998, Dr. Riess published the first evidence that the expansion of the Universe was accelerating and was filled with Dark Energy, a result which was called the Breathrough Discovery of the Year by Science Magazine that year.

Riess has received numerous awards for his work in astrophysics, most noticeably, the Robert J. Trumpler Award from the Astronomical Society of the Pacific, the Bok Prize from Harvard University, the AURA Science Award from STScI, and the Helen B. Warner Prize from the American Astronomical Society, the Raymond and Beverly Sackler Prize, the Shaw Prize in Astronomy, the Gruber Cosmology Prize, and most recently, the Einstein Medal in 2011.

Riess was the winner of MacArthur "Genius" Grant in 2008 and was elected to the National Academy of Sciences in 2009.

(Texas A&M University)

Dr. Lucas Macri is an Assistant Professor of Physics & Astronomy at Texas A&M University, and a member of the George P. and Cynthia Woods Mitchell Institute for Fundamental Physics & Astronomy.

Dr. Macri was born in Buenos Aires, Argentina. He majored in Physics at Massachusetts Institute of Technology and obtained his Ph.D. at the Harvard-Smithsonian Center for Astrophysics. He was a Hubble and Goldberg fellow at the National Optical Astronomy Observatory in Tucson, AZ before moving to Texas A&M.

He has studied Cepheid variables in nearby spiral galaxies as part of several projects aimed at measuring the expansion rate of the Universe (the Hubble constant) with increasingly higher accuracy and precision.
