Professional
- Since September 2024, I have been an elected member of the Steering Committee of the Irish Mathematical Society (three-year term), and of its subcommittee developing a schedule of IMS prizes.
- In June 2025, I was co-organiser, with Eimear Byrne, Ronan Egan and John Sheekey, of the first Dublin Discrete Mathematics Workshop (DDMW2025), held at UCD and DCU, 23–27 June 2025. This resulted in a special issue of the Journal of Algebraic Combinatorics, which is currently being finalised. The workshop received funding from DCU and UCD.
- Co-founder of the DCU–UCD Discrete Mathematics Seminar series.
- In 2018 I was guest editor, with Dardo Goyeneche and Ilias Kotsireas, of the special issue of Mathematics in Computer Science (vol. 12, no. 4) arising from the 2017 Budapest workshop on Hadamard matrices, complex Hadamard matrices and applications.
- In 2014 with Luke Morgan and Eric Swartz, I organised the Algebra/Combinatorics section of the Eighth Australia New Zealand Mathematics Convention, University of Melbourne.
Údarás na Gaeltachta
- Member of the AI steering committee
- November 2026: co-organiser of 2-day conference "Todhchaí na dteicneolaíochtaí teanga i ré na hintleachta saorga" a conference on AI and minority languages hosted by Údarás na Gaeltachta in Galway.
- October 2026: participated in International AI Summit organised by the Department of Enterprise, Tourism and Employment at the RDS, Dublin.
Dublin City University (2022–2025)
- Programme Chair, Gnó agus Gaeilge, 2022–2025. I initiated a programme of school visits and an Irish-language university day for Gaelcholáistí students; enrolment grew from 7 students in 2022 to 19 in 2025.
- I developed a series of workshops on AI Awareness, delivered in Gaeilge and English for third level educators. This was delivered at campuses in Limerick, Dublin and Thurles as well as online; over 100 lecturers participated in total.
- I developed a 2-day workshop on techniques in linear algebra aimed at graduate students, covering normal forms for linear transformations and quadratic forms; and applications in algebra and combinatorics. This event was delivered multiple times in Ireland, as well as in Australia, Croatia and Finland.
- Contributed to the development of institutional policy on AI and academic integrity.
Worcester Polytechnic Institute (2016–2021)
- 2020–21: Chair of the (elected, campus-wide) Committee on Advising and Student Life.
- 2020–21: Member of the Graduate Program Committee, Department of Mathematical Sciences. I developed, and brought to the department for approval, a syllabus for the Graduate Comprehensive Exam in Linear Algebra, and in 2020 chaired the committee that set, delivered and graded three GCE exams.
- 2016–2020: Member of the Undergraduate Committee, Department of Mathematical Sciences.
Refereeing and Reviewing: I have written approx. 100 referee reports for approx. 30 journals, including those listed below.
