 iversité de Montréal\,\nCharles J. Amick Memorial Lecturer 2009-2010\, U
 niversity of Chicago\nWe will present some recent mathematical and numeric
 al contributions related to two multiscale problems. The first problem ste
 ms from our wish to model a periodic microstructure with embedded defects:
  our goal is then to construct a numerical approximation of the solution t
 hat is accurate at the vicinity of the defects. The second problem is a pr
 oblem set on a perforated domains\, with perforations possibly heterogeneo
 usly located throughout the domain. We introduce a MsFEM type approach wel
 l suited for the situation under consideration.  The works are joint work
 s with Xavier Blanc (Paris 7) and Pierre Louis Lions (College de France) f
 or the former problem\, and Frederic Legoll (Ecole des Ponts) and Alexei L
 ozinski (Universite de Besancon) for the latter problem.
