The hunt for SUSY at ATLAS: current status and challenges for Run 2

The LHC has restarted operations in 2015, and the experiments are efficiently collecting 
data at 13 TeV center-of-mass energy since several months. With a wide and 
comprehensive program of searches, ATLAS is hunting for Supersymmetry (SUSY), one 
of the most compelling theories beyond the Standard Model. In this talk, I will review the 
results of the Run 1 searches and the constraints on SUSY particle masses placed using 
8 TeV data, as well as first Run 2 results and the many challenges on the way for discovery.
