MAIN RESEARCH INTERESTS

My research program explores the interface between quantum gravity phenomenology, nuclear astrophysics, and quantum field theory, with a unifying focus on testing fundamental physics through both theoretical modeling and observational signatures. At the core of this effort lies the development of beyond-Standard-Model frameworks that probe the limits of spacetime symmetry, high-energy interactions, and emergent gravity.

 

In quantum gravity phenomenology, I investigate:​​

• Higher-order gravity in arbitrary dimensions, where derivative expansions modify Einstein-Hilbert dynamics and black hole solutions, with implications for renormalizability and unitarity;

• Analogue gravity models in condensed-matter systems, which simulate exotic spacetime geometries (e.g., acoustic horizons) to test semiclassical gravity predictions;

• Lorentz symmetry violation (LSV) via the Standard Model Extension (SME), constraining spacetime anisotropy through astrophysical neutrinos, gamma-ray bursts, and gravitational waves.

 

My work in nuclear astrophysics connects these theoretical constructs to extreme environments:​

• Neutron star interiors as laboratories for modified electromagnetism (e.g., nonlinear Maxwell extensions) and nonminimal couplings;

• Neutrino propagation in strong magnetic fields, with attention to spin-flip transitions and magnetic moment anomalies;

• Exotic compact objects with quark matter or topological defects (e.g., magnetic monopoles), where higher-derivative terms alter mass-radius relations.

​

Within quantum field theory, I specialize in:​

• Neutral-particle electrodynamics, including Aharonov-Casher-type effects and emergent gauge structures;

• Gyromagnetic ratio deviations from Dirac’s prediction, probing composite models or spacetime granularity;

• Nonminimal couplings (e.g., axion-photon, curvature-fermion) that generate testable thresholds in high-energy collisions or cosmic-ray spectra.

 

This integrated approach—spanning mathematical consistency, astrophysical viability, and experimental constraints—aims to identify observational windows into quantum spacetime structure while advancing the dialogue between formal theory and multimessenger astronomy.
