In the past decade, we have detected hundreds of gravitational waves, advancing our understanding of the Universe and its governing laws. In this talk, I will present the theoretical models and data analysis tools I have developed for interfacing...

Abstract: Machine learning (ML) is an increasingly vital tool at the Compact Muon Solenoid (CMS) experiment at CERN’s Large Hadron Collider, from online data collection to offline interpretation. I will trace how ML is driving new-physics discovery...

LIGO, Virgo, and KAGRA have recently announced the discovery of over 200 new compact binary mergers in low latency during their fourth observing run (O4), a majority of which are stellar-mass binary black hole mergers. The first segment of this run...

Abstract: The Laser Interferometer Space Antenna is a planned space-based detector that will measure gravitational waves in the milli-hertz regime. One of the primary targets for LISA is an extreme mass ratio inspiral (EMRI), where a stellar mass...

Abstract: Atomically thin crystals form a vast family of 2D quantum materials, with only a few well studied. Engineered structures like stacked 2D crystals and moiré superlattices offer exceptionally rich and highly tunable platforms for exploring...

Cosmological observables, from the Lyman-alpha forest to the Milky Way substructure, offer unique avenues for probing dark matter and neutrino sectors. Moreover, they often reveal anomalies and tensions that could signal new physics. I will review...

The commonly observed Type Ia supernovae likely occur when one star in a binary undergoes a sudden detonation triggered by the transfer of mass from a closely orbiting companion. Due to the short orbital period of 5-10 minutes of many explosion...

Abstract: Classical" accretion disks are geometrically thin, radiatively efficient and mechanized by turbulent viscosity. Yet, many observational and theoretical issues challenge this standard model, suggesting that we are missing essential-but...
