**About the role**: Telecommunication networks virtualization will facilitate dynamic physical resources allocations to virtual functions and services. In particular, automatization of dynamic counter-measures (CM) placements and dynamic network reconfiguration (moving target defense - MTD) will be allowed. Some recent works aim at exploiting this capacity in term of CM placements, in order to stop/reduce cyber-attacks [Bazgan et al. ; Mahjoub et al, 2018]. However these solutions only consider static or bi-level solutions that do not take into account future evolutions of the network state for making decisions. Other recent works around MTD concern real-time network reconfiguration, that consists, for instance, of regularly making servers offline over time [Eghtesad et al., 2019], changing IP addresses continuously, dynamically change virtual machines locations, etc. [Sengupta, 2020]. Finding optimal policies of such reconfigurations is a real challenge because this need to seek optimization/planning algorithms for very large states space and under uncertainty. **About you**: PhD in computer science or applied mathematics that has to be defended after (inclusive) October 2019 and not been realized in Orange. Specialty: decision science, operations research, optimization, A PhD in optimization/planning under uncertainty, in particular in the domain of Markov decision processes will be appreciated. **Additional information**: **Department**: The ambition of the Innovation Division is to take Orange's innovation further and strengthen its technological leadership, by mobilizing our research capacities to foster responsible innovation in the service of people, to clarify the Group's strategic choices term and influence the global digital ecosystem. We train experts in the technologies of today and tomorrow, and ensure continuous improvement in the performance of our services and our efficiency. The Innovation division brings together 6,000 employees worldwide dedicated to research and innovation, including 740 researchers. Holders of a global vision with a wide variety of profiles (researchers, engineers, designers, developers, data scientists, sociologists, graphic designers, marketers, cybersecurity experts, etc.), the women and men of Innovation are attentive and countries, regions and business units to make Orange a trusted multi-service operator. "Within Innovation, you will be integrated into a research team at the forefront of innovation and expertise on the networks of the future (5G+, virtualization, fixed-mobile convergence, mobile edge computing, Named Data networking, ).You will be part of a research ecosystem alongside engineers of studies in anticipation (shorter term) allowing the concrete implementation of the concepts studied, benefiting from simulation platforms (4G/5G)”. **Contract**: Post Doc
