Post Summary
Novel optical access and metro networks are essential to support fast growing capacity requirement, driven by future applications and services for 6G and beyond. Networks are also evolving to support a large variety of signals across larger access and metro network areas. For these novel scenarios, flexibility becomes an essential feature, driven by the development of flexible components and open networks.
Development of Digital Twins, capable of building dynamic models from information gathered form live networks become essential to manage network requests, while maintaining high availability and optimal resource utilization.
One Post Doctoral researcher position is available to work in the area of Digital Twins for optical networks, making use of intelligent AI-driven control planes.
The applicants should have a solid theoretical background on machine learning and optical networks and willing to engage in testbed-oriented research. The work will be carried out in the OpenIreland research infrastructure, a large-scale testbed for experimentation in open optical, wireless and cloud technologies.
The position will be based in the School of Computer Science and Statistics, with Prof. Ruffini research team and affiliated with the ADAPT research centre on AI, at Trinity College Dublin, Ireland and will be funded under the Research Ireland Investigators award project. The researcher will have the opportunity to build their research portfolio within a range of projects within the team. The position will be under the direction of Prof. Marco Ruffini.

Standard Duties and Responsibilities of the Post

The primary focus of the EPR will be to perform research on the National Research Ireland project, although they might also work on other projects. In addition, the EPR’s activity will be broader and the EPR is also expected to:

• • Conduct a specified programme of research under the supervision and direction of the Principal Investigator
  • Engage in the dissemination of the results of the research in which they are engaged, as directed by, with the support of and under the supervision of the Principal Investigator. (Actively publish research findings in high impact journals and at key conferences as part of the research group effort to disseminate research outputs).
  • Engage in the wider research and scholarly activities of the research group, School or University
  • Interact closely with postgraduate research students associated with the same research group and possibly have an agreed role in supporting these students in their day-to-day research in conjunction with an academic supervisor.
  • Take leadership and contribute to generation of papers, reports and other funding proposals.
• • Carry out administrative work to support the program of research where required, including regular funding agency reports and internal reports etc.
  • Carry out additional duties as may reasonably be required within the general scope and level of the post.
  • Support collaboration with industry in areas relevant to the research group
  • Engage in appropriate training and professional development opportunities as required by the Principal Investigator, School or University, in order to develop research skills and competencies.
  • Gain experience and contribute to grant writing with the support of and under the supervision of the Principal Investigator
  • Acquire generic and transferable skills (including project management, business skills and postgraduate mentoring/supervision).
• • Contribute to broader outreach and engagement activities such as organising technical meetings, outreach to schools and other interested parties etc.
