Quantum mechanically a black hole emits thermal radiation and has an entropy equaling a quarter of its surface area in Planck units. This implies the existence of black hole microstates, something inconceivable in classical gravity! In fact, the appearance of Planck units suggests Quantum Gravity holds the key to the puzzle.

String theory, a candidate for the theory of quantum gravity, succeeds in explaining how black holes might have microstates. Furthermore, it reproduces black hole entropy from counting black hole microstates. I will discuss how this remarkable feat is achieved, and will touch upon my contribution in this field.
