* Branching processes with random environment: theory and applications

We have been working on branching processes with random environment, not necesaarily Markovian. Our main contributions concern non-Markovian migration. This allowed us to study the role of correlation in many queueing models, such as networks of infinite server queues as well as polling models. We studied both discrete as well as continuous state models.
