DESCRIPTION:The advent of attosecond technology and the generation of inte
 nse ultrashort laser pulses raises the possibility\nto investigate atomic\
 , molecular\, and nuclear physics at this new time-scale\, bringing a revo
 lution in our microscopic\nknowledge and understanding of matter. Two fasc
 inating and complementary challenges of Attoscience are to identify\nthe p
 hysical mechanisms underlying the correlated multi-electron dynamics--of f
 undamental interest to\, for instance\, molecular\nimaging--in atomic syst
 ems and to devise schemes to probe/control these mechanisms.\n\nWe discuss
  first the mechanisms underlying the correlated electron dynamics for two 
 fundamental processes: a) non-sequential double ionization in\nstrongly dr
 iven He b) multi-electron ionization by a sequence of attosecond collision
 s when a single photon is absorbed by multi-electron atoms.\nCurrently\, t
 he state of the art is time-resolving multi-electron effects in processes 
 where one electron leaves the atom.\nFor the first time\, we present the t
 wo-electron streak camera that allows for time-resolving electron-electron
  correlation of\nintra-atomic collision dynamics.\n\n\n
