Originally started as a forum for particle physicists to discuss recent developments in lattice gauge theory, the conference has since expanded to the largest of its type, covering a wide range of topics including algorithms and machines, code development, physics within and beyond the Standard Model, and other strongly interacting systems.

New Directions in Theoretical Physics is a series of international conferences organised by the Higgs Centre for Theoretical Physics, aiming to highlight new opportunities and stimulate an exchange of ideas across all areas of contemporary theoretical physics. All talks are plenary reviews aimed at a broad audience of theoretical physicists, intended to inspire and to promote valuable cross-disciplinary interactions.

This is an informal summary of: Variations on the Maiani-Testa approach and the inverse problem. The idea of this work, completed with Mattia Bruno at CERN, is to connect some new ideas for calculating scattering amplitudes via lattice QCD with a seminal publication on the topic, the work of Maiani and Testa published in 1990.

This is an informal summary of: The energy-dependent $\pi^+ \pi^+ \pi^+$ scattering amplitude from QCD, published in PRL. In some ways, this work represents the culmination of a many-year effort going back to my PhD thesis in 2014.

This is an informal summary of: The role of boundary conditions in quantum computations of scattering observables. There has recently been a major push, worldwide, to accelerate the development of quantum technologies and especially quantum computing.
