Abstract: Recent measurements of the Hubble Constant (H_0) through distance ladder techniques have revealed a noticeable tension with the Planck H_0 value that was obtained under the assumption of the cosmological "standard model", i.e., a flat Lambda cold dark matter …

Abstract: Many fundamental properties of neural networks are still not well understood. This talk studies two of these from an adversarial perspective. I begin with my main line of research and examine the apparently-fundamental susceptibility of neural networks to adversarial …

ABSTRACT: Weak-scale Supersymmetry can help to resolve several puzzles presented by the Standard Model, including the nature of dark matter and the naturalness of the Higgs mass, and has motivated a robust search program at the Large Hadron Collider. Searches …

Abstract: Cosmological inflation is the leading hypothesis to resolve the problems in the Big Bang theory. It predicts that primordial gravitational waves were created during the inflationary era, which then imprinted large-scale curl patterns in the cosmic microwave background (CMB) …
April 2018 marks the 2nd data release (DR2) of the ESA Gaia space mission. A new era in astrometry begun. Accurate positions, proper motions and parallaxes for over a billion stars are now available on the sub-mas level. The properties …

ABSTRACT: This talk will present the first measurement of monoenergetic muon neutrino charged current interactions. The MiniBooNE experiment at Fermilab has been used to isolate and study 236 MeV muon neutrino events originating from charged kaon decay at rest. The …
ABSTRACT: The central puzzle that drives the field of quantum foundations is the measurement problem: what gives rise to the appearance of wave function collapse? While there is no single answer to this question that has wide acceptance, this is …
Abstract The radiation environment at the High Luminosity LHC requires CMS to replace its silicon tracker with one that is more radiation hard and granular. The new tracker is designed twenty years after the original one, and has new unique …

ABSTRACT: Current cosmological measurements have left us with deep questions about our Universe: What caused the expansion of the Universe at the earliest times? How did structure form? What is Dark Energy and does it evolve with time? New experiments …
Abstract: The identification of hadronically decaying tau leptons at the LHC is challenging. I will review the methods for tau reconstruction at ATLAS and how the identification of tau leptons has enabled several interesting and novel measurements in exotics and …
