Donal O'Mahony graduated with first class honours in Engineering from Trinity College Dublin in 1982. His first job was with SORD Computer Corporation in Japan and Dublin. Sord was a Japanese startup company with aspirations to displace Apple as the then leader in micro-computers. O'Mahony served as their operating system specialist, working with CP/M, CP/M-86, the UCSD P-System, Sord's proprietary operating system and the emerging MS-DOS. A brief exposure to the new IBM PC in late 1982 caused him to go to work with IBM Ireland helping to launch the original IBM PC. He was recruited by Trinity College as a lecturer in Computer Science in 1984 where he later completed a PhD in the area of software reusability.
Around 1990, he set up the Networks & Telecommunications Research Group which did pioneering work in the esablishment of the global X.500 directory service (initially implemented over an academic X.25 network infrastructure called IXI) and in using the system in a wide variety of applications including a pre-web form of electronic commerce. In 1988, when Local Area Networks were beginning to appear on the mass-market, he published a textbok with Prentice-Hall publishers entitled Local Area Networks and their Applications which became a best-seller in this emerging field and was subsequently published in Japanese, Polish as well as in a low-cost edition for the Indian market. . His research group took part in the Cordless Business Communication (COBUCO) European project in 1996 which aimed to produce a demonstrator for the emerging 3G mobile cellular system. This experience led the group to develop a vision for 4G systems that eschewed traditional cellular architectures for a more interenet-like system that provides seamless mobility, end-to-end security across a network operated by very many competing nework operator. This vision is still being actively pursued today.
The group has also been very active in the development of novel security protocols, in particular in Electronc Payment and in 1997, he and two of his research students published Electronic Payment Systems with Artech House. This book became the leading text in this area, went to 2nd edition, and was awarded a 'best seller in class" award by Amazon.Com in 2000.
In 1998/99, O'Mahony was awarded a Fulbright scholarship to spend a sabbatical year at Stanford, California. In addition to his research work at Stanford he became involved with the very active technology entrepreneurship programme. He started a web company called LetterPost.Com in late 1998. A business plan was developed in conjunction with a colleague and entered into Stanford Entrepreneur's E-Challenge where it was repeatedly subjected to the scrutiny of judges from the Sand Hill road venture capital community and reached the final of the competition. O'Mahony continued as CEO of letterpost.com until it was acquired by the Escher Group in 2000.
O'Mahony is a senior member of the IEEE and was made a fellow of Trinity College in May 2000
