Dark matter is a mysterious substance that constitutes 85% of the matter in our universe. Although its existence has been established from the enormous gravitational influence that it exerts in the evolution of the universe, its fundamental nature remains unknown. An exciting possibility is that dark matter is made of particles that interact very weakly with atoms to induce low-energy nuclear or electronic recoils in an instrumented target on Earth. I will present the DAMIC program, which searches for dark matter signals in the bulk silicon of charge-coupled devices (CCDs) deployed deep underground. I will also present the status of Selena, a novel detector concept inspired by DAMIC that is uniquely capable to address important questions in neutrino physics and astrophysics.
