Abstract
Formulating a quantum theory of gravity lies at the heart of fundamental theoretical physics. This collection of lecture notes encompasses a selection of topics that were covered in six mini-courses at the Nordita PhD school "Towards Quantum Gravity". The scope was to provide a coherent picture, from its foundation to forefront research, emphasizing connections between different areas. The lectures begin with perturbative quantum gravity and effective field theory. Subsequently, two ultraviolet-complete approaches are presented: asymptotically safe gravity and string theory. Finally, elements of quantum effects in black hole spacetimes are discussed.

Report
The field of quantum gravity is very active and quite large. The present set of lectures gives a pedagogic introduction to the topic presented by very active young theorists. The notes start with the most important introductory material - the quantization of General Relativity and its treatment as a perturbative Effective Field Theory. This material includes a treatment of Quadratic Gravity, which forms a prelude for a subsequent description of Asymptotic Safety. String Theory is described in an introductory way. Finally the many issues posed by black holes is covered.
These lectures cover many topics which are crucial for understanding forefront work on quantum gravity. They are well-done.
I recommend publication for these lecture notes.
