Faculty and Research Fellows

Sarp Akcay Assistant Professor My research interests are in mathematical and computational general relativity, with specific focus on modelling compact binary inspirals and mergers that are detectable by either ground-based or space interferometers. I have done work in the fields gravitational self-force, effective-one body theory, gravitational waveform modelling for both decaHertz and milliHertz regimes, and gravitational wave parameter estimation. I am a member of the LISA Consortium and was previously a member of the LIGO-Virgo-KAGRA Collaboration.
Chris Kavanagh SFI-IRC Pathway Fellow My research focuses on analytic approaches, such as the post-Newtonian / post-Minkowskian approximations and gravitational self-force, to modelling black-hole binaries and their gravitational radiation as sources for gravitational wave detectors. I am also interested in the interplay between methods used for gravitational wave physics and those used for scattering problems in particle physics.
Adrian Ottewill Emeritus Full Professor I have over 30 years Faculty experience at Oxford University and UCD with a long record of research supervision of PhD and postdoctoral students in classical and quantum gravity with particular emphasis on gravitational wave astronomy, quantum field theory and wave propagation in curved space-time. I am a Fellow of the Institute of Physics and Royal Astronomical Society and have been a Member of the Royal Irish Academy for over 20 years.
Christiana Pantelidou Assistant Professor and RS–RI URF My research focuses on understanding non-linear phenomena in gravitational physics, including the phenomenon of gravitational turbulence and its potential astrophysical and cosmological ramifications. I am also interested in gravity in AdS and its relation to fluid dynamics through the AdS/CFT correspondence, real-time holography, quasinormal modes, black hole stability, and numerical relativity. I am very enthusiastic about public outreach and about promoting matters of Equality, Diversity and Inclusion.
Barry Wardell Associate Professor My research interests involve the study of black holes, gravitational waves and cosmic strings. I am particularly focused on numerical and perturbation theory approaches to solving Einstein’s equations of General Relativity. I co-lead the Multiscale Self-Force collaboration, am a member of the LISA DDPC, am a founding developer of the Black Hole Perturbation Toolkit, have contributed to the Einstein Toolkit, and am PI on the EMRIWaveforms ERC Advanced Grant.
Niels Warburton Assistant Professor and RS–RI URF My research centres around modelling gravitational wave emission from compact binary systems, with a particular emphasis on using black hole perturbation theory to model small mass-ratio systems. I am an active member of the LISA Consortium where I was the co-chair the Waveform Working Group and a coordinator for the EMRI waveform Working Package from from 2018-2024. I am currently a member of the LISA DDPC and the LISA Consortium Council.
Marc Casals Visiting Professor I am a Research Professor at the University of Leipzig, Germany, and a Visiting Professor at UCD. My research is in General Relativity and Quantum Field Theory in curved spacetimes, with a particular interest in classical and quantum black holes. On the classical side, my work ranges from black hole stability properties to black hole binary inspirals and gravitational waves. On the quantum side, my work covers Hawking radiation, quantum backreaction and higher-dimensional black holes.

Postdoctoral researchers

Susanna Barsanti Postdoc with Niels Warburton My primary interest focuses on modelling gravitational waves emitted by asymmetric binary systems, in particular Extreme Mass Ratio Inspirals (EMRIs), both in General Relativity and beyond. I am currently developing modified EMRI waveforms in alternative gravity theories and I am also interested in LISA data analysis with extreme and intermediate mass ratio inspirals.

PhD and MSc students

Kevin Cunningham RI PhD Fellow with Niels Warburton I am interested in modelling Extreme Mass Ratio Inspirals using Black Hole Perturbation Theory and self-force techniques, as well as gravitational wave memory effects, and metric reconstruciton techniques. I am a contributor to the Black Hole Perturbation Toolkit.
Chris Devitt RI PhD Fellow with Barry Wardell I am working on applying self-force techniques to modified theories of gravity, such as scalar-tensor and vector-tensor theories, with the goal of placing constraints on these theories.
Jakob Neef PhD researcher with Chris Kavanagh My work focuses on weak field expansions of self-force to obtain analytical solutions describing EMRI dynamics. Some of my work is available through the Black Hole Perturbation Toolkit. My PhD is funded by Research Ireland.
Giulio Taiocchi PhD researcher with Christiana Pantelidou I did my bachelor and master in Milan, and I did my master thesis in Lisbon at the Centra Group. I mainly work with asymptotically Anti de Sitter space time, through numerical methods, and I am interested in turbulent behaviours in General Relativity and Fluid Dynamics. My supervisor is Christiana Pantelidou.
Tien Van Truong MSc student with Barry Wardell I am studying full-time at University College Dublin for a MSc degree in Applied Mathematics & Theoretical Physics. I have experience in fundamental particle physics & cosmology from my Bachelor degree. I am studying resonant orbits around black holes for my Master thesis. My supervisor is Dr Barry Wardell.
