Improved understanding of quantum chromodynamics (QCD) is crucial for advanced precision in LHC data analysis: nearly all LHC collisions used in physics analysis contain jets of hadronic radiation produced by QCD. Jets are reconstructed using signals from the ATLAS inner tracking detector and calorimeters, and calibrated using in situ techniques. Differential cross-section measurements of jets and jet substructure are multi-faceted physics analyses that enable the testing of new theoretical predictions including resummed analytical predictions and higher-accuracy parton shower Monte Carlos. In this seminar, I will review the prospects for extractions of Standard Model parameters from jet substructure, and I will present new measurements of novel event shape observables performed by ATLAS that are constructed using interdisciplinary data-science techniques.
