Abstract: Event Horizon Telescope (EHT) observations of M87* provide a means of constraining parameters of both the black hole and its surrounding plasma. However, intrinsic variability of the emitting material introduces a major source of...

Abstract: Recently a fruit fly brain was reconstructed in electron microscopic detail. Tens of millions of synapses were identified on over 100,000 neurons' entangled branches, which would span a football field if unraveled end to end. This "fly...

In the era of high-dimensional data and simulation-based science, machine learning is transforming the different stages of the scientific method in astrophysics. I will present a summary of my research connected to generative models in two main...

Recent breakthroughs in gravitational wave and electromagnetic observations have given better and better insights into black holes and extreme gravity. While one usually thinks of black holes as the unyielding final state of gravitational collapse...

Abstract: Black holes (BHs) can acquire magnetosphere and horizon-penetrating magnetic fluxes from plasma inflow or mergers with magnetized neutron stars. Several numerical studies have shown that a black hole magnetosphere relaxes into a split...

Abstract: As the LHC moves into its high-luminosity era, discovery potential will hinge not just on data volume, but on the intelligence of real-time selection systems. The CMS experiment processes petabytes of data every second, using an FPGA-based...

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...
