Development of high-precision frameworks for the observation and interpretation of gravitational waves from compact binary coalescences, focusing on parameter estimation and numerical relativity comparisons.

Research Topics

• Parameter Inference: Pankow et al., “Novel scheme for rapid parallel parameter estimation of gravitational waves from compact binary coalescences”
• NR Comparisons: Healy et al., “Second RIT binary black hole simulations catalog and its application to gravitational waves parameter estimation”, Gayathri et al., “Eccentricity estimate for black hole mergers with numerical relativity simulations”
• LVK O3 Results: The LIGO Scientific Collaboration et al., “The population of merging compact binaries inferred using gravitational waves through GWTC-3”, Abbott et al., “Observation of Gravitational Waves from Two Neutron Star-Black Hole Coalescences”

Impact

• Major contributions to gravitational wave observations within the LIGO Scientific Collaboration (e.g., O3 populations paper, O3a catalog, NSBH discovery).
• Inference of eccentricity for event GW190521.
• Provision of science leadership and infrastructure for partner coalitions using RIT frameworks for source and population inference.
