Observational routes into the puzzles of gravity, cosmology, and the quantum universe.

I work on astrophysics, cosmology, and the physics of gravity, with a particular interest in observational hints that can address fundamental questions.
I study how quantum gravity may alter black-hole horizons, interiors, entropy, and singularities, with the aim of turning microscopic models into observable signatures.
I develop waveform, time-frequency, and Bayesian methods for testing strong gravity with present and future observatories, including ringdown spectroscopy, stochastic backgrounds, LISA sources, and post-merger echoes.
I explore how ultraviolet-complete, holographic, and quantum descriptions of gravity can explain cosmic initial conditions, tested against inflationary predictions and precision cosmology.
I investigate whether cosmic acceleration and current cosmological tensions reveal departures from general relativity, including cuscuton-like theories, horizon-scale Lorentz violation, and scale-dependent gravity.
I use cosmological simulations, analytic models, and interpretable machine learning to map dark objects and understand nonlinear structure, from dark-galaxy prediction to halo outskirts and phase space.
I use the thermal and kinematic Sunyaev–Zel’dovich effects to trace hot electrons, galaxy motions, and the baryonic content of halos and intergalactic space while separating radio, dust, and infrared foregrounds.
I study observable signatures of black holes, neutron stars, white dwarfs, and modified strong gravity. Accretion spectra, self-lensing, and eclipses complement gravitational-wave tests.
I investigate operational and analogue probes of quantum spacetime, from detectors in superposed geometries to condensed-matter systems that reproduce black-hole thermodynamics, alongside surveys of unresolved foundational questions.
I apply statistical and multiscale physics to radiation transport, microscopic energy deposition, and temperature profiles in tissue. This work helps clarify the mechanisms that shape FLASH ultra-high-dose-rate radiotherapy and other particle-therapy responses.
During the COVID-19 pandemic, I developed data-driven models of local epidemic growth that separated the effects of population density, demographics, climate, susceptible depletion, and interventions. The work connected transparent modelling to public dashboards and accessible public communication.
