Projects and research interests

XMM-Newton Survey Science Centre (SSC):

development and maintenance of the source-detection software tasks
development of stacked source detection
development and compilation of the source catalogue from overlapping observations

XMM2ATHENA consortium (2021-2024):

WP4 co-lead "Enhanced stacked catalogue"
based on a re-engineered source-detection strategy, optimised for higher sensitivity to very faint X-ray sources
contributions to sensitivity estimator, variability assessment, source classification, science validation, and other Work Packages

Source detection in stacked observations

Late stages of stellar evolution:

data analysis and spectral modeling
X-ray and multi-wavelength diagnostics of magnetic cataclysmic variables
compact objects, white dwarfs in binaries and planetary nebulae
