Construction and analysis of quasi-local isolated horizons for near-horizon spacetime models.

Addressing challenges of overlapping compact binary coalescences in future gravitational wave detectors. Developing techniques for identification and characterization to enhance parameter estimation accuracy. Gained expertise in matched filtering (PyCBC), unmodeled analysis (cWB), and Bayesian parameter estimation (bilby).

Comprehensive study of non-circular encounters in the context of gravitational wave ringdowns, through fitting techniques and the reconstruction of waveforms that capture the physics of eccentric, non-circular mergers.

Study of decoherence of stationary superpositions in spacetimes with Killing horizons. Analysis framed via the local two-point function of quantum fields and applications to black hole induced decoherence.

Implementation and testing of quadratic mode injections, development of parameter estimation strategies, and analysis of the detectability of non-linear/quadratic ringdown modes.

Enhancements to inspiral–merger–ringdown (IMR) consistency tests using time-domain analyses: algorithmic improvements, SNR threshold refinement and investigation of higher-mode systematics on GR tests.

Constructing high-resolution density and peculiar velocity field maps using DESI galaxy-survey data and neural networks. Aims to enable velocity-field reconstructions for cosmological analyses of dark matter and dark energy.
