The Drell-Yan process provides a versatile platform for a multitude of physics research, from precision Standard Model measurements and searches for new physics, to detector efficiency studies. This talk covers two analysis conducted during my PhD using Drell-Yan processes with the ATLAS experiment. Firstly, a precision cross-section measurement of the charged-current Drell-Yan process using the full Run 2 dataset, performed at high-transverse masses beyond the resonant W peak region - a region previously not measured. Secondly the neutral-current Drell-Yan process was used to perform a luminosity measurement during 2022, a process known as Z-counting. This measurement is used at ATLAS to monitor the stability of the primary luminosity measurement.
