DESCRIPTION:Dr Jean-Luc Starck\, Head of the CosmoStat Laboratory\, CEA-Sa
 clay\, France\nSince the dawn of time\, humans have been wondering about t
 heir place in the Universe.  Over the past century\, advances in modern p
 hysics\, technology and engineering\, along with the unique possibilities 
 offered by space missions\, have opened new windows to explore the cosmos.
  All-sky surveys\, with observations across the entire electromagnetic spe
 ctrum\, are the best strategy to fully understand and model the Universe i
 n detail. Major upcoming research facilities\, such as the Large Synoptic 
 Survey Telescope (LSST)\, the Square Kilometer Array (SKA) and the Euclid 
 space telescopes will provide key elements to addressing this challenge\, 
 by producing high quality data of petabyte volumes.\n\nThese surveys prove
  to be a major “big data" challenge\, which require the development of i
 nnovative statistical methods essential both for the data analysis and the
 ir physical interpretation. I will present some highlights of this methodo
 logy and more specifically show how novel techniques of sparsity and compr
 essed sensing open new perspectives in analysing cosmological data. These 
 enable us to answer fundamental questions about the nature of our Universe
  with impressive accuracy.\n\nBio: Jean-Luc Starck is Director of Research
  and head of the CosmoStat laboratory at CEA-Saclay\, France. He obtained 
 his Ph.D from Nice Observatory in 1992 and an Habilitation from University
  Paris XI in 1999. He was a visitor at the European Southern Observatory i
 n 1993\, at UCLA in 2004 and at Stanford in 2000 and 2005. Since 1994\, he
  has been a tenured researcher at CEA\, where in  2010 he founded the Cos
 moStat laboratory\, an interdisciplinary research group with a focus on in
 dustry-academia partnership.\n\nProf. Starck has been heavily involved in 
 many ESA space missions\, including the upcoming Euclid space mission. He 
 is the recipient of the 2011 EADS prize of the French Academy of Science. 
 He has published over 200 refereed papers in astrophysics\, cosmology\, si
 gnal processing\, and applied mathematics\, as well as three textbooks.
