Professor In (Computer Science)
OREILLY INSTITUTE


Declan O'Sullivan is a Professor in Computer Science in the School of Computer Science and Statistics. He is a co-champion of the Trinity Digital Engagement interdisciplinary theme, and a Principal Investigator at the Science Foundation Ireland (SFI) ADAPT Research Centre (http://www.adaptcentre.ie). He was Head of the Discipline of Artificial Intelligence from 2012-2018. He was Director of Research and Deputy Head of School from 2017 to 2023.

Declan was presented with an "Excellence in Supervision of Research Students" award from Trinity in 2024. He was also elected as a Fellow of Trinity College Dublin for the quality of his research and contribution to college in 2019. He was awarded a B.A. (Mod) in Computer Science from TCD in 1985, an M.Sc. in Computer Science from TCD in 1988, and a Ph.D. in Computer Science from TCD in 2006. Declan has 13 years of research experience in industry, having worked for IONA Technologies from 1995 to 2001 and from 1988 to 1995 with Broadcom Eireann Research. During this time he achieved a successful track record as lead researcher, and in coordinating international research projects and the transfer of research into products.

He is currently primary supervisor for 7 Phd students: Jeffrey Sardina, Matt Murtagh-White, Claire Mc Namara, Sarah Alzahrani, Ali Bandeh, Mary Sharp, Gaye Stephens and co-supervising 2 PhD students: Delaram Golpayegani in TCD and Jiantao Wu in UCD.

He has supervised 25 Phd students to completion since 2006 as primary supervisor (19) or co-supervisor (6) : Albert Navarro; Alex Randles; Sinead Impey; Peru Bhardwaj, Lucy Mc Kenna; Harshvardhan Pandit; Gachpaz Hamed Roghaiyeh; Wessel Reijers; Haytham Assem; Ademar Crotti; Michael Glienecke; Alan Meehan; Brian Walsh; Hendrik Thomas; Seung-Hwa Chung; Paul Stynes; Liam Fallon; Wei Tai; Dominic Jones; Colm Conroy; Bo Fu; Aidan Boran; Song Guo; Ruairdhi Power; Karl Quinn, as well as the following 7 MSc by Research Theses completions : Rolando Hanlon, Sahil Mathur, Tewson Seeoun; Mark Stokell, Rami Shosha, Paul Mara and Austin Kenny. In addition he has supervised 65+ MSc Dissertations to date. Those he has supervised have continued their careers either as postdoctoral researchers in academia (with some now holding their own faculty positions) or by joining in a variety of technology companies and progressing into senior roles.

Declan O'Sullivan and his team are developing new theoretical, conceptual and algorithmic techniques for automated data integration in dynamic environments. The integration step of the data lifecycle has typically been a labour intensive activity, with increasingly brittle results due to the dynamic nature of today's environments. A systematic mechanism for continuous data integration is lacking, but is needed to deal with the dynamism of the data (velocity, variety) and schemata characteristics of modern environments. The team has particular expertise in W3C-based Knowledge Graphs, Semantic Web and Linked Data environments.
