How he started using computation. How he went from being a postdoc researcher in Bristol to joining a consulting firm and what he learned there. • 05:40 • You went from not liking computers and Fortran to enjoying it during your PhD and consultancy. Next thing you are director of computing services in UCD. Quite a career path! • Dennis talks about how he made the transition from physics to computing using the skills he had learned in UCD and consultancy and why he wanted to move back into a university. • Developing and running the computing early infrastructure in UCD and building up the computing resources for the campus and researchers. • 1982 making the first proposals for what became HEANET. • 10:30 • You had this interest in networking technologies. At some point during your time in UCD you were offered the secondment to the National Science Foundation (NSF) • Dennis talks about how he got the position of Director of Networking at the NSF to build a network of networks to allow computer users to use the national supercomputer centre, using a common set of protocols and standards (TCP/IP) • 17:50 • Do you think it would go to where it is now? Did you foresee what it is today (Internet of Things / “always connected”). What is the next big thing? • Dennis talks about the contribution that computer scientists have made to science. The impact of AI and machine learning developments but the problems of training them on poor datasets. The difference between the Internet and applications that run on it and the pressing need for regulation of applications, services and data. • 24:45 • Bringing it back to people considering computer science or a PhD. Do you have any advice? • How to make choices when looking at an undergraduate degree. What a good education gives you. Looking back on his own choices. How to make a change of direction and overcome setbacks and mistakes.
