Staff Profile

Dr Danielle Leonard

Lecturer in Astronomy


I am interested in testing and constraining extensions to the standard cosmological model, especially alternative theories of gravity and dynamical dark energy. To do this, I use observables which are sensitive to the growth of large-scale structure, in particular weak gravitational lensing and galaxy clustering.

I also work on weak gravitational lensing and galaxy clustering more generally, including improved methods for mitigating, and exploiting astrophysical modelling uncertainties such as the intrinsic alignment of galaxies and galaxy bias.

In general, I am excited by any project which involves unpacking standard assumptions in cosmological analyses to ensure that our findings are as robust as possible.

I am a member of the Large Synoptic Survey Telescope Dark Energy Science Collaboration (LSST DESC).

In Fall 2019, I am the Lecturer for PHY 1021, Introductory Astrophysics.
