Abstract: The most sensitive searches for dark matter (DM) with mass above ~10 GeV/c2 use the dual-phase xenon time-projection chamber (LXe-TPC) technology. In the U.S., development of this technology is spearheaded by the LUX-ZEPLIN experiment, with first science data coming …
- Abstract: In order to infer cosmological parameters from data of upcoming surveys like DESI, we will use summary statistics such as the power spectrum. An accurate estimate of their covariance matrix is crucial for the inference analysis. The traditional process …
Abstract: What is the nature of dark matter? What leads to the fundamental forces having such disparate strengths? Can we explain the small mass of the Higgs boson without excessive fine tuning? These outstanding questions are part of a broad …
Abstract: The talk will present my PhD project research which focuses on advancing the standardization of various transients to be used as cosmological probes and the evaluation of the Hubble constant (H0). With SN Ia, I will present interesting results …

Abstract: Modeling galaxy-dark matter connection is essential in deriving unbiased cosmological constraints from galaxy clustering observations. We show that a more physically motivated galaxy-dark matter incorporating secondary biases can result in more accurate predictions of galaxy clustering, and that it …
Abstract: Accelerator-based, long-baseline neutrino oscillation experiments are uniquely positioned to explore the CP-violating nature of the neutrino sector. This talk will briey discuss the experimental technique before surveying selected topics spanning both current and future generations of such experiments. First, …
Abstract: MicroBooNE is a Liquid Argon Time Projection Chamber (LArTPC) detector and is the first of three such detectors to be commissioned as part of the Short Baseline Neutrino (SBN) program at Fermilab (FNAL), and has been taking data since 2015. One …
Abstract: Large-scale structure (LSS) surveys have exploded in size over the last few decades, cataloguing the locations and shapes of hundreds of millions of galaxies. The unprecedented precision enabled by such datasets puts extraordinary demands on the control of systematic …
Abstract: The Standard Model of particle physics described the interactions between the elementary particles that compose our universe. To study these interactions, protons collide at very high energies at the Large Hadron Collider, generating hundreds of particles through every bunch …
Abstract: The Higgs boson is the only fundamental spin-0 particle in the Standard Model (SM) of particle physics, associated with an ever-present field that is the source of mass and linked to electroweak symmetry breaking, making it a particle …
