Dr Roger Giddings received his BEng (Hons) degree in Engineering Science and Technology from Loughborough University in 1989. He was awarded a PhD degree in Optical Communications in January 2012 from Bangor University.

In 1990 he joined Nokia Networks UK where he worked as a HW Design Engineer and Senior HW Design Engineer in the Advanced Primary Multiplexers Group & SDH Products Group. In 1998 he moved to Finland to continue working for Nokia Networks, in the SDH Access Products group where he worked on the HW development of Nokia’s first Optical Fiber Amplifier products. In 2000 he moved to Nokia’s Research Center as a Senior Research Engineer in the Computing Architectures Laboratory where he worked on various projects including Nokia’s first demonstration 3GPP system and designing and prototyping new product innovations for Nokia’s Business Units. In 2004 he joined the Nokia Emerging Business Unit as a Senior Hardware Specialist where he was the chief HW architect and designer for novel concepts in portable multimedia and personal communication consumer devices.

In 2007 he returned to the UK and joined the Optical Communications Research group at the School of Electronic Engineering, Bangor University, working  as an Experimental Researcher and studying for his PhD degree in the area of high speed optical communication systems for next generation optical networks. He successfully implemented an experimental system to demonstrate real-time DSP-based Optical OFDM transmission which was the world’s first Optical OFDM system capable of real-time end-to-end transmission at >10Gb/s. This work was part of the European-funded project ALPHA www.ict-alpha.eu.

In 2012 has was awarded a lectureship and was promoted to senior lecturer in 2016, he continues to research DSP-enabled optical communication systems to achieve dynamically reconfigurable optical networks that seemlessly converge traditional metro, access and 4G/5G mobile fronthaul/backhaul.

During his research at Bangor he has (co)authored more than 100 papers published in refereed professional journals and international conferences. He also acts as a reviewer for several leading journals, has acted as program chair and a TPC member for the SPPCom conference and was recently guest editor for a special issue of the Future Internet journal. http://www.mdpi.com/journal/futureinternet/special_issues/DSP_Optical

Digital signal processing (DSP) has recently emerged as a highly promising technology for meeting the high demands placed on future optical networks such as high capacity, cost-efficiency, green networks and highly flexible networks. This research area is focused on the application of DSP in optical communications to solve the future network challenges. Our world-leading real-time DSP-based optical communications test bed will be fully utilised to explore areas such as: advanced modulation techniques for escalating the data capacity of a single optical wavelength, driving the improvement in power efficiency at both the optical transceiver and network level and enhancing optical network resource utilisation through network aware intelligent optical transceivers.

• IET Openhouse Event 2023

  On the 14th of June, the School of Computer Science and Electronic Engineering hosted an IET Openhouse event where we opened our doors to the public to showcase the exciting world of STEM.

  The Engineering Open House Week is a constituent part of the Engineer a Better World campaign by the IET (The Institution of Engineering and Technology), aiming to inspire children to explore the captivating realm of STEM and explore the wide range of innovative and rewarding professions available in modern engineering.

  The event was tailored for children aged 5-13 and their parents / guardians, and we lined up three exciting and interactive activities for them to engage with. The NFI (Nuclear Futures Institute) gave a tour of their brand-new laboratory facilities, and also had some hands-on demos for children to interact with, including Lego Mindstorms and outreach equipment on loan to the NFI from Magnox, and the DSP Centre (Digital Signal Processing Centre) had the participants build their own torches and learn about Morse code, and then sent an encrypted Morse code message down an optical fibre for others to decrypt. Finally, Technocamps had them battle it out as code breaking teams to solve a number of mind-bending clues in order to open a box before other teams, or before their time ran out.
