Dionysios graduated from Cornell University, and obtained his PhD at Harvard University under the supervision of Professor Andrew Strominger. After that he held research positions at Stanford University, the Institute for Advanced Study, and was the Delta ITP fellow at the University of Amsterdam. In 2018 he was awarded a University Research Fellowship from the Royal Society and moved to King’s College London.

Research interests

Dionysios’ research lies at the interface of black hole physics, cosmology and the gauge/gravity duality. An important goal of Dionysios' research is to extend modern ideas such as the AdS/CFT correspondence to a more general class of spacetimes. These include spacetimes experiencing an accelerated phase of expansion, including those describing our own Universe during its early and late time cosmological epochs. The models and mathematical tools Dionysios applies in his research include higher spin gauge theories, matrix models, conformal field theory, Euclidean quantum gravity, lower dimensional models, and the theory of disorder and glassiness. One of Dionysios' research aims to construct and develop simplified models of cosmological spacetimes that exhibit enhanced mathematical control. In turn, such models can be studied throughout regimes where standard tools describing physical phenomena at low energies or large scales, such as effective field theory, need to be replaced.
