Abstract: 

The nature of dark matter, such as its mass and interactions, remains elusive despite the convincing evidence for its existence from the astrophysical observations.
The environment around the black hole can provide us a promising playground to study the dark matter properties due to the large density of dark matter accreting to the black hole.
I will explore the multi-messenger probes on the dark matter in the vicinity of black holes. More concretely, I will discuss how the gravitational waves can probe the dark matter effects on the black hole binary evolution, and how the enhanced dark matter annihilation around a black hole can be probed by the neutrinos and the multi-wavelength signals covering the radio, CMB and gamma rays.
