The University of Galway invite applications for a fully funded 4-year PhD position in Theoretical High-Energy Physics, funded by the Research Ireland Pathway grant “Integrability in Non-Lorentzian Holography” led by Andrea Fontanella, starting in September 2026.
The main focus of the PhD project is to further develop the recently discovered non-relativistic and Carrollian holography, to construct integrability techniques for non-Lorentzian theories, and to explore applications of non-Lorentzian holography to flat space holography.

Turning noise into signal with soft matter models
Abstract
For more than a hundred years, scientists have carefully analysed the apparently random fluctuations in Brownian trajectories to learn about soft systems. In a more general sense, however, the information hidden within experimental fluctuations is typically underexploited, due to challenges in unambiguously linking fluctuation signatures to underlying physical mechanisms. In this talk, I will discuss our recent work developing new approaches to interpreting fluctuations in experimental data from a variety of soft systems, and thereby turn ‘noise’ into signal. In particular, I will share some recent results taking a fresh look at fluctuations in equilibrium colloidal monolayers. Here, we have combined experiment, simulation and theory to explore how simply counting colloids can reveal details of self and collective dynamics in interacting systems [1,2,3]. I will then discuss ongoing work to extend this understanding to confined driven systems [4], with the long-term goal of elucidating characteristic fluctuations in our synthetic nanopore experiments [5].
