Where

Graduate course on Supergravity for first Ph.D. students at Scuola Normale

Lectures delivered at SISSA (2006/07-2009/10) at the EPFL (Spring 2009), at the LACES School 2009 and LACES 2021, at the SEPnet (Queen Mary, Uni. Southampton, Royal Holloway, Spring 2010) and at the Scuola Normale Superiore (Pisa, Winter 2011, Winter 2018 and Winter 2019).

The LACES 2021 lectures are also visible on YouTube.
