The topic of my thesis is the disentanglement and characterisation of gravitational wave signals sourced by different astrophysical objects that would be detected by the future Laser Interferometer Space Antenna (LISA).

LISA is expected to detect a plethora of gravitaional wave signals from different astrophysical sources once in mission. While containing rich information on the sources, the signals are usually long-lived and superposing in the LISA data. It is thus crucial to disentangle and characterise these signals to infer astrophysical models for the formation and evolution of the population of the compact binaries. I work on the data analysis techniques which need to be robust and capable to deal with growing volume of the data, accumulated as observation time goes.
