Biography

Ronan has been a member of technical staff in Bell Labs since September 2011 and is primarily working on Vibration Energy Harvesting (VEH) for wireless sensor networks. He also contributes to projects on autonomously powered ICT equipment and thermal management (such as cooling of high density photonic integrated circuits). Ronan is based in Dublin, not far from his home town of Swords. His background is in Aeronautical Engineering and holds a PhD degree from research related to damage mechanics of composite materials for aircraft structures. Both B.Eng and PhD. degrees were received from the University of Limerick, Ireland.

Ronan has experience in both experimental and numerical analysis techniques, with a particular emphasis on non-linear finite element modelling and now uses these skills in Bell Labs to overcome various technology challenges for the ICT sector. Ronan’s main research area on energy harvesting for wireless sensor networks is a topic that generates a lot of interest with so many technical and non-technical people since everyone understands the pain of having to recharge or replace batteries! Ronan also has a keen interest in thermal management issues, which are an interesting and persistent set of challenges that can exist in many types of ICT equipment.
