Dear colleagues,

Please be informed of the following seminar:




SCHOOL of ENGINEERING SEMINAR

“Cosmostatistics: Tackling Big Data from the Sky”

Dr Jean-Luc Starck
Director of Research
Head of the CosmoStat Laboratory
CEA-Saclay, France

Monday – November 28, 2016 – 14h00
EPFL – room SV1717


Abstract: Since the dawn of time, humans have been wondering about their place in the Universe.  Over the past century, advances in modern physics, 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 spectrum, are the best strategy to fully understand and model the Universe in 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. These surveys prove to be a major “big data" challenge, which require the development of innovative statistical methods essential both for the data analysis and their physical interpretation. I will present some highlights of this methodology and more specifically show how novel techniques of sparsity and compressed sensing open new perspectives in analysing cosmological data. These enable us to answer fundamental questions about the nature of our Universe with impressive accuracy.

Short bio: 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 in 1993, at UCLA in 2004 and at Stanford in 2000 and 2005. Since 1994, he is a tenured researcher at CEA, where in  2010 he founded the CosmoStat laboratory, an interdisciplinary research group with a focus on industry-academia partnership. He has been strongly 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, signal processing, and applied mathematics, as well as three textbooks.





Best regards,
Pascal
