Title: Professor in Theoretical Physics
Dario Martelli studied Physics at the University of Pisa and the Scuola Normale Superiore of Pisa, and obtained his PhD from the International School of Advanced Studies in Trieste. He held research positions at CERN in Geneva, and the Institute for Advanced Study in Princeton among others.
In 2010 he joined the Department of Mathematics of King's College as a Lecturer in Theoretical Physics. He was appointed Reader in 2012 and became a Professor in 2013. He held a five-year EPSRC Advanced Fellowship and has recently been awarded a prestigious ERC Starting Grant to lead a research team working on a research project at the interface of string theory, gauge theory, and geometry.
In 2010 Professor Martelli won the SIGRAV Prize from the Italian Society of General Relativity and Gravitational Physics for his work in string theory. He wrote a number of publications in collaboration with Prof S.-T. Yau, concerning Sasaki-Einstein geometry and its relationship to string theory, and worked with Prof J. Maldacena on aspects of the string theory/gauge theory correspondence.
Dario's research interests are centred around the gauge/gravity correspondence in string theory and geometric structures arising in this context. In particular, he is interested in supergravities and their supersymmetric solutions. The class of solutions based on Sasaki-Einstein manifolds is an instance where the interplay of geometry with the AdS/CFT correspondence has led to advancements on both sides. He discovered the first example of an infinite family of Sasaki-Einstein metrics and obtained important results in Sasakian geometry.
Recently his work has focused on supersymmetric gauge theories in the background of curved manifolds. In particular, he has been studying localization techniques that allow to obtain analytic results in the context of strongly coupled quantum field theories, and the embedding of these in string theory via the gauge/gravity duality.
Another line of research concerns applications of the AdS/CFT duality to study physical systems arising in condensed matter physics, possibly with non-relativistic symmetries. In particular, he is interested in holographic applications of consistent Kaluza-Klein trancutions of supergravity theories.
