Data-Intensive AstroNomical Analysis [D.I.AN.A.]
I lead the D.I.AN.A group at the University of Bristol. In the past, I co-lead the AGN Work Package in Euclid (2019-2025).
My group uses large multiwavelength datasets to understand the impact of supermassive black holes in the evolution of galaxies. We develop automated methods for creating high-fidelity multiwavelength datasets, harness machine-learning methods for object classification & physical parameter estimation, and explore the impact of AGN in galaxy evolution through the statistical analysis of large datasets.

Public Codes
Star - Galaxy - QSO classification [GitHub]
Unsupervised machine-learning classification - application of HDBSCAN
classify sources using photometry
method presented in Logan & Fotopoulou 2020
Astro-PostgreSQL Docker image [GitHub]
Run a PostgreSQL deamon through docker, including the pg_sphere and pg_healpix extensions.
pg_sphere provides astronomy related definitions such as points, coordinates, etc
pg_healpix provides access to tessellation ID of sky coordinates.
AstronomicAL [GitHub]
An interactive dashboard for visualisation, integration and classification of data using Active Learning presented in Stevens et al., 2021
INSPEC-Z [GitHub]
Interactive visualisation and verification of 1D spectra with matplotlib.
Convenience functionality for managing large surveys, e.g. filtering, flag homogenisation
Simple conda installation and docker image (only for Mac OS)
Self-hosted AI [GITHUB]
Run LLMs with additional context locally, server them your peers, maintain privacy.
