My research is presently focused on the Hamiltonian structure of gravitational gauge theories, i.e. generalisations of Einstein's general relativity (GR) to include torsion, non-metricity and scale-invariance. The Hamiltonian formulation can further constrain such theories which are apparently ghost-free and causal.
My talk at the CfH conference covers some previous work from this year:
I have separate interests in the BBGKY hierarchy (though not in a gauge gravity context), cosmological tensions and neural networks.
I have previously worked on gravitational energy localisation and gravitoelectromagnetism in GR.
