Mars and frame-dragging: study for a dedicated mission
, 2008 In this paper we preliminarily explore the possibility of designing a dedicated satellite-based mission to measure the general relativistic gravitomagnetic Lense-Thirring effect in the gravitational field of Mars.

Semiclassical Analysis of the Wigner $9J$-Symbol with Small and Large Angular Momenta
, 2011 We derive a new asymptotic formula for the Wigner $9j$-symbol, in the limit of one small and eight large angular momenta, using a novel gauge-invariant factorization for the asymptotic solution of a set of coupled wave equations.

Sparse Bayesian mass-mapping with uncertainties: hypothesis testing of structure [PDF]
, 2018 A crucial aspect of mass-mapping, via weak lensing, is quantification of the uncertainty introduced during the reconstruction process. Properly accounting for these errors has been largely ignored to date.

The vacuum seagull: evaluating a 3-loop Feynman diagram with 3 mass scales
, 2017 We study a 3-loop 5-propagator Feynman Integral, which we call the vacuum seagull, with arbitrary masses and spacetime dimension using the Symmetries of Feynman Integrals method. It is our first example with potential numerators.

Duals of nonabelian gauge theories in $D$ dimensions
, 1994 The dual of an arbitrary $D$-dimensional nonabelian lattice gauge theory, obtained after character expansion and integration over the gauge group, is shown to be a {\em local} lattice theory in the eigenspace of the Casimir operators.
