Dr. Michael Schukat

Dr. Michael Schukat leads the OSNA research group. He is a Lecturer in the Discipline of Information Technology @ NUI Galway since 2002. His research interests include cyber security (with particular focus on (time synchronisation) network security), real-time embedded systems and medical informatics.

Originally from Germany, he studied Computer Science and Medical Informatics at the University of Hildesheim, where he graduated with an M.Sc. (Dipl. Inf.) in 1994. He continued his research there and received a Dr. rer. nat. for his work in the area of DC powered magnetic flow meters in 2000. Between 1994 and 2002 he worked in various industry positions where he specialised in deeply embedded real-time systems for industrial control, medical devices, automotive subsystems and network storage systems.

Dr. Hugh Melvin

Dr. Hugh Melvin  is based at the Discipline of Information Technology, NUI, Galway since 1997. His technical and strategic role within OSNA stem from his background and interests in Real-Time Systems, cybersecurity, and SmartGrid.  More generally, his research scope extends to  Internet Multimedia, Timing Systems, Wireless Technologies, and Energy & Environmental Informatics.  Prior to 1997, he worked for 9 years in Power Engineering, latterly as  Maintenance Manager (Electrical & Control) for the 1000MW ESB Moneypoint Power Station.   Graduated with a B.E from UCD in 1988,  an MBA from University of Limerick in 1997, a Research M.Sc from NUI Galway in 2000, and a PhD from University College Dublin in 2004. He is also a co-chair of the NIST public working group on cyber-physical systems.

He also manages the Performance Engineering Laboratory research group at NUI Galway (PEL), which though having a broader ICT scope, dovetails significantly with that of  OSNA. His expertise in Power Systems and ICT provides useful building blocks for his work on SmartGrid and related cybersecurity challenges.

Dr. Padraig O Flaithearta

Dr. Padraig O Flaithearta

Padraig joined OSNA in 2015 as a Research Associate and Network Engineer after having received his Ph.D from NUI Galway. As part of his doctoral work Padraig specialised in time synchronisation protocols and developed a novel network delay calculation mechanism using RTCP, which enables the accurate calculation of one-way delay across networks and thus enables QoS improvements for multimedia applications.
Padraig’s areas of expertise are in wireless networking, time synchronization systems, network delay optimization, network protocols, software-defined networking, telecommunications, cyber security and IoT. Padraig is also a member of the Performance Engineering Laboratory (PEL).

Joe Desbonnet

Joe is an software engineer with over 20 years of experience in software development. He was a founder of ‘Galway.Net’ one of the world’s first commercial database driven city guides in 1994 and has since been involved in several startup businesses in the internet and technology space.
Joe has extensive experience with the Linux operating system, having been using it daily since 1993. He was very active in the evangelizing the technology in the early days, giving talks and attending major Linux conferences. Joe has used Linux as a server operating system (having run web application servers from this platform since the dawn of the web) but also in desktop, kiosk and embedded applications configurations.
He currently has a technology consultancy company and is actively involved in research projects the National University of Ireland, Galway. In his spare time Joe blogs about technology ( and is an active contributor to open source projects in the electronics/embedded software area.

Pablo Cortijo M.Sc.


Pablo contributes to OSNA’s developments as a PKI specialist. He graduated at the Universidad Politécnica de Madrid as a Computer Engineer in 2003, and has ever since worked in the field of Computer Security. He has participated in numerous innovative security projects – he notably designed and deployed a series of very large (some nation-wide), resource-demanding PKIs that were used as part of e-Passport and e-ID inspection/issuance systems. His technical background includes other security domains, such as Identity and Access Management/Control.
