Research & Publications
My research lies at the interface of theoretical astrophysics, astroparticle physics, gravitational-wave physics, and computational modeling.
I study compact objects as extreme laboratories for dark matter and beyond-standard-model physics. In particular, I am interested in how neutron stars, binary neutron-star systems, strong magnetic fields, dense matter, and dynamical spacetime curvature can generate observable signatures of hidden sectors.
My research trajectory has evolved from boson stars and gravastar models to dark-matter effects in neutron stars, gravitational-wave signatures in compact binaries, and axion/ALP–photon couplings in strongly magnetized relativistic systems.
