Eamonn de Leastar is currently co-founder and Chief Technical Officer of the Telecommunications Software Systems Group (TSSG).

After graduation in 1982, he taught computer science at Dundalk Institute of Technology, where he was responsible for a range of new curricula within this sector. He then moved into industry, gaining significant experience in senior programmer, analyst, quality assurance and project leadership roles. This included periods at Wordstar International, developing some of the first work processors on the then newly established PC standard and at Contel Business Systems porting the Unix operating system to a new range of hardware. In the early 90s, while compiler group team leader at Glockenspiel Ltd, he oversaw the implementation of the first commercial C++ compilers on a range of platforms.

Since 1992 he has worked at Waterford Institute of Technology as a Lecturer in Computer Science, establishing the TSSG with colleagues in 1997. Prior to the establishment of the group his research interests were dominated by real time process control applications, where he developed and led the implementation of a range of control applications with Honeywell Measurex (calibration and head control systems) and Waterford Crystal (tank furnace monitoring). During this period he completed an MSc by research in process control- developing an innovative approach to controlling PLC devices via C++ application framework technology.

Since the establishment of the TSSG, Mr. de Leastar has been a member of the management team, and led a range of research projects ensuring that the TSSG is one of the most successful groups within the Irish third level sector. He has acted as technical director of SUSIE and Bandwidth programmes and led the RBS programme.

Eamonn de Leastar received a BSc (Hons) in Computer Science in 1982, and an MSc in Computer Science in 1994, both from University College Cork.
