Hunting for Sub-GeV Dark Matter: From the SENSEI experiment to Oscura and Beyond

This presentation will focus on the SENSEI experiments, the first to use Skipper-CCD technology to search for sub-GeV Dark Matter (DM). I will discuss recent results from SENSEI, showcasing our progress from initial prototypes to current findings at the underground SNOLAB facility. Additionally, I will introduce Oscura, a follow-up experiment that promises to expand our DM search capabilities significantly. Finally, I will touch on the DarkNESS mission, the first space initiative to utilize Skipper-CCD technology, which offers a unique perspective for DM exploration.
