In this article we consider a branching random walk defined as follows. It starts with a unique individual located at position 0 at time 0. At each integer time n, we choose a point process law $P_n$ at random. Then every individual currently alive dies, giving birth to children according to i.i.d. point processes with law $P_n$. We take interest in the impact of this random environment on the maximal displacement of the process.
