*Black holes* are one of the most fascinating predictions of
Einstein’s general relativity. With a high-resolution image of a supermassive
black hole at the center of M87 by the Event Horizon Telescope and recent
gravitational wave observations of binary black hole collisions by LIGO at hand,
there are no longer any doubts that black holes exist in our Universe. However,
the very existence of black holes still raises many *fundamental theoretical
questions*. Those related to quantum processes, such as the mystery of black
hole entropy, information loss, quantum evaporation and black hole
thermodynamics, are expected to provide key insights towards understanding how
to reconcile gravity with quantum theory. Other are purely classical and range
from describing astrophysical processes to pure mathematical physics.

In
this project we are going to investigate certain aspects of black hole physics,
the specific topic being determined by the taste of the student and recent
developments in the field. This may include my *current interests* (see
https://inspirehep.net), such as the
“black hole chemistry” and its holographic interpretation, probing the
quantum information aspects of spacetimes with the Unruh-De Witt detector, or
purely classical investigations of separability of various test field equations
in black hole backgrounds employing hidden symmetries. I am also very open to
novel ideas and directions.
