As a general fact, directed polymers in random environment are localized in
the so called strong disorder phase. In this talk, based on a joint with Francis Comets, we will consider the exactly solvable
model with log gamma environment,introduced recently by Seppalainen.
For the stationary model
and the point to line version, the localization can be expressed as the trapping
of the endpoint in a potential given by an independent random walk.
