The Interdisciplinary Centre for Security, Reliability and Trust (SnT) invites applications from highly motivated PhD candidates in the general area of machine learning and radio resource allocation for emerging wireless networks within its Signal Processing and Communications (SIGCOM) research group. SnT carries out interdisciplinary research in secure, reliable and trustworthy ICT systems and services, often in collaboration with industrial, governmental or international partners. For further information, you may refer to

The SIGCOM research group is headed by Prof. Symeon Chatzinotas, and mainly carries out research activities in the areas of signal processing for wireless communication systems, including satellite communications, and is currently expanding its research activities towards quantum information systems. Use cases of interest include IoT verticals, unmanned aerial vehicles, integrated satellite-space-terrestrial networks, quantum communications and key distribution, spectrum management and coexistence, tactile Internet, and autonomous transportation. Furthermore, our activities are experimentally driven and supported by the SDR CommLab, the SDN Lab, the 5G-Space Lab, our SW Simulators, and our OTA Facilities.

We’re looking for people driven by excellence, excited about innovation, and looking to make a difference. If this sounds like you, you’ve come to the right place!

Your Role

The successful candidate is expected to work on an emerging topic of Semantic and Task-oriented Communications Design for 6G Networks. The purpose of this project is to develop a novel communication design paradigm for multi-agent cyber-physical 6G systems which simultaneously maximizes the task effectiveness metric and the network resource usage. The developed task-oriented communication design is expected to apply to various important application domains, such as Industrial IoT, Multi-UAV systems, and multi-layer wireless networks.

The successful candidate will work under the supervision of Prof. Symeon Chatzinotas and Dr. Thang X. Vu and join a strong and motivated research team lead by Prof. Symeon Chatzinotas.

The position holder will be required to perform the following tasks:

  • Work on an emerging research topic of Semantic and Task-oriented communications design for 6G networks
  • Carry out research in the predefined areas
  • Disseminate results through scientific publications in the top-tier venues
  • Present results in top-tier international conferences and workshops
Your Profile

Qualification: The candidate should possess a Master degree in Electrical Engineering, Computer Science, or equivalence.

Experience: The ideal candidate should have some knowledge and experience in a number of the following topics:

  • Background in one of some topics in wireless communications: multiuser system, resource allocation, scheduling
  • Optimization techniques and tools: convex optimization, successive convex approximation, stochastic gradient decent
  • Experience in machine learning (both theory and application) and/or multiagent reinforcement learning is an asset
  • Programming skills in MATLAB are required. Experience in Python is an advantage

Language Skills: Fluent written and verbal communication skills in English are required.

Here’s what awaits you at SnT
  • A stimulating learning environment. Here post-docs and professors outnumber PhD students. That translates into access and close collaborations with some of the brightest ICT researchers, giving you solid guidance
  • Exciting infrastructures and unique labs. At SnT’s two campuses, our researchers can take a walk on the moon at the LunaLab, build a nanosatellite, or help make autonomous vehicles even better
  • The right place for IMPACT. SnT researchers engage in demand-driven projects. Through our Partnership Programme, we work on projects with more than 55 industry partners
  • Multiple funding sources for your ideas. The University supports researchers to acquire funding from national, European and private sources
  • Competitive salary package. The University offers a 12 month-salary package, over six weeks of paid time off, meal vouchers and health insurance
  • Be part of a multicultural family. At SnT we have more than 60 nationalities. Throughout the year, we organise team-building events, networking activities and more
  • Boost your career. Students can take advantage of several opportunities for growth and career development, from free language classes to career resources and extracurricular activities

But wait, there’s more!

In Short
  • Contract Type: Fixed Term Contract 36 Month (extendable up to 48 months if required)
  • Work Hours:  40.0 Hours per Week
  • Location: Kirchberg
  • Employee and student status
  • Job Reference: UOL05061

The yearly gross salary for every PhD at the UL is EUR 38979 (full time)
