Research
Professor Andreopoulos’ research is primarily focussed on precision measurements of neutrino mixing and new physics searches in the intensity frontier, neutrino interaction phenomenology and quantum information science.
Precision measurements of neutrino mixing and new physics searches.
I am centrally involved in preparations for the physics exploitation of the Fermilab Short-Baseline Neutrino (SBN) Program, in particular in the SBN Near Detector (SBND) and I am the PI of the Liverpool SBN team. I have served as a member of the SBND Executive Committee (2020-2023), member of the SBN Results Approval Committee (2023), chair of the SBND Speakers Committee (2019-2022), SBND Physics co-Coordinator (2017-2023), and Systematics & Oscillation Sensitivity WG co-Coordinator (2018-2022) for the overall SBN programme. I direct sterile neutrino oscillation analyses for SBN using the Liverpool-led VALOR analysis and develop methods using SBND-PRISM and high-statistics SBND data to refine neutrino–argon interaction models, constrain systematic uncertainties, and enable new physics searches at the O(1%) level. See here for the Liverpool SBN page.
I also participate in the physics exploitation of the Jiangmen Underground Neutrino Observatory (JUNO) in Southern China, near Hong Kong and Guangzhou. I am the PI of the Liverpool JUNO team and a new member of the international JUNO collaboration. My research focuses on ML-based event reconstruction, physics simulations, atmospheric neutrino studies aiming to enhance the JUNO neutrino mass ordering sensitivity, and dark sector searches. See here for the Liverpool JUNO page.
Previously, I was a member of the T2K experiment in Japan where, over the past decade, I performed flagship oscillation measurements. As founder and coordinator of the VALOR fitting group, I led the development of several peer-reviewed oscillation analyses between 2010 and 2020, contributing to numerous published T2K papers - an effort that culminated in the 2020 Nature paper on T2K neutrino CP violation constraint.
Information about our prolific contributions to T2K can be found here and here.
Comprehensive neutrino interaction modelling and global analysis of neutrino scattering data.
I am co-spokesperson of the international GENIE collaboration, and one of the main authors of the well-known GENIE event generator, as well as of the corresponding global analysis of neutrino scattering data informing GENIE tunes. GENIE conducts influential phenomenology research in the interface of nuclear and particle physics. It provides a bridge between theory and measurement, playing a central role in the interpretation of modern neutrino data.
Quantum computing applications in Particle Physics
I have a keen interest in Quantum Information Science, particularly its potential to transform computational approaches in fundamental physics.
Together with with researchers from the Fermilab Quantum Institute and PhD students at Liverpool, I'm involved in an exciting project to advance the frontier of quantum simulations for particle physics, with a focus on nuclear effective field theories (EFTs) relevant to neutrino interactions. We explore fault-tolerant quantum algorithms for simulating nuclear dynamics, from ground-state preparation to observable extraction. By comparing qubit-based and hybrid oscillator–qubit platforms, we aim to reduce the resource overhead of simulating pion dynamics, opening new possibilities for tackling classically intractable problems in neutrino-nucleus scattering.
