| Dr Laverty is a Reader with the School of EEECS at Queen’s University Belfast. His work is mainly focused on Electrical Power System metrology and time transfer technology, with adjacent work in data systems, cyber security and machine learning. He has expertise on low carbon technology and sustainable generation systems, as well as electric vehicles and battery systems. He is known as the founder of the open source project “OpenPMU”, a device which produces accurate time synchronised observations of electrical power system phenomena.
Recently he has been working to address the vulnerability arising from reliance on “space-based” time to synchronise power system apparatus. He has developed novel methods to detect GNSS spoofing attacks using commodity equipment. Protocols such as PTP and SyncE, although widely utilised in substations and data centres, do not lend themselves to wide area distribution over public networks. NRENs provide an opportunity to investigate challenges and solutions towards creating national time transfer networks. Dr Laverty is working on terrestrial time transfer technologies using mixed media (fibre and microwave) to provide resilient time transfer to critical national infrastructure. |
