Resonant searches at INFN
At INFN Laboratori Nazionali di Frascati, I coordinate the Theory Work Package of FLASH, developing the modelling and interpretation of axion and high-frequency gravitational-wave signals in a resonant haloscope.
I am a theoretical physicist at the University of Salerno and INFN working at the interface of particle physics, astrophysics, and cosmology. I use the Universe and precision experiments as laboratories for new fundamental physics, with particular emphasis on axions and ultralight particles, dark-matter substructure, black holes, gravitational waves, and dark energy.
My research connects early-Universe dynamics and nonlinear structure formation to concrete observables in haloscopes, radio telescopes, gravitational-wave detectors, atomic sensors, and cosmological surveys. I coordinate the Theory Work Package of FLASH and co-developed ASTRA, a radio programme searching for axion conversion in neutron-star magnetospheres.
Before joining Salerno in 2025, I was a Tenure-track Associate Professor at Shanghai Jiao Tong University and a Fellow at the Tsung-Dao Lee Institute, a Marie Skłodowska-Curie FELLINI Fellow at INFN Frascati, a GRAPPA Fellow at the University of Amsterdam, and a postdoctoral researcher at NORDITA in Stockholm.
My work has received the 2021 Buchalter Cosmology Prize (Third Prize) and an NSFC Research Fund for International Excellent Young Scientists for the project Astrophysical Axion Laboratories.

Fundamental physics across the early Universe, the sky, and precision experiments.
My research is organized around four connected questions: how new light particles are produced, how they structure the Universe, how they interact with compact objects, and how they can be detected.
From early-Universe production to miniclusters, streams, axion stars, and dark radiation, I study how light bosonic fields evolve and which observables preserve their cosmological history.
Explore this theme 02I translate axion and high-frequency gravitational-wave theory into measurable signals for resonant haloscopes, radio telescopes, atomic sensors, and multimode detector networks.
See active programmes 03I use primordial and astrophysical black holes, superradiance, compact binaries, and high-energy messengers as precision probes of dark sectors and gravity.
Explore this theme 04I investigate dark energy, cosmological tensions, neutrino interactions, cosmic strings, reionization, and departures from standard thermal and expansion histories.

My work increasingly connects fundamental theory to experimental design, signal modelling, and observational strategy.
At INFN Laboratori Nazionali di Frascati, I coordinate the Theory Work Package of FLASH, developing the modelling and interpretation of axion and high-frequency gravitational-wave signals in a resonant haloscope.
I co-developed ASTRA, a radio search for QCD-axion conversion in neutron-star magnetospheres. The programme links theory, telescope strategy, and signal modelling across a multi-year observing campaign.
I initiated Green Bank Telescope searches for axions in Andromeda and contribute to broader efforts using resonant detectors, atomic sensors, and multimessenger observations to test ultralight physics.

A hybrid detector framework extending gravitational-wave searches from radio to optical frequencies.
Connecting ultralight dark sectors to time-dependent signatures in neutrino oscillations.
Exploring energetic particle production from evaporating ultralight black holes.
A telescope strategy for transient radio signals from dense axion structures.
Establishing transient radio bursts as a probe of axion miniclusters.
A systematic map of axion constructions, phenomenology, and experimental targets.
Training researchers across theory, computation, and experiment.
I supervise projects spanning axion phenomenology, cosmology, compact objects, gravitational waves, and data analysis for experimental searches. Students are encouraged to connect formal modelling with observables, build reproducible numerical tools, and collaborate internationally.
I welcome enquiries from motivated MSc and PhD students interested in theoretical astroparticle physics. A useful first message includes your CV, transcript, research interests, and the timescale or funding route you are considering.
Projects are based at the University of Salerno and INFN and can involve collaborators in FLASH, telescope programmes, Virgo/LVK, and partner institutes across Europe, China, and the United States.

Monte Carlo modelling shows that observable streams should be rare, recent, and dynamically cold, with spectral widths narrower than typical haloscope bandwidths.
