Brief CV

Research Interests

Born and raised near Bologna, Italy, I studied there and obtained my Master Degree in 2007 and Ph.D. in 2011 from the University of Bologna. During my Ph.D., I was a visiting student at UC Davis, California, for six months. I spent four more years at the Physics Department in Bologna as a postdoctoral researcher, in the group of Prof. Fiorenzo Bastianelli. Over these years I worked mainly on the so-called worldline formalism, a first-quantized approach to quantum field theory that shares many features with the worldsheet approach to string theory.

In 2015 I moved to the University of Mons (Belgium) for a three-year postdoc position in the group of Prof. Nicolas Boulanger, where I focused on interacting higher-spin gauge theories. At the same time, I worked on adapting the worldline formalism to provide a first-quantized description of gravity.

Since 2018, I have been a postdoctoral researcher in the group of Prof. Olaf Hohm at Humboldt University in Berlin. Here I initially worked on \(\alpha'\) corrections with manifest T- duality symmetry and universal formulations of gauged supergravities, in terms of higher algebraic structures. The interplay between the worldline formalism and the homotopy algebra techniques applied to quantum field theory is at the core of my current scientific interests. In particular, since 2022 my research is devoted to establishing a first-principle derivation of the so-called double copy, a remarkable relation between gauge and gravity scattering amplitudes. This program involves several members of the group and crucially relies on homotopy algebraic techniques. Its long-term goal is to formulate perturbative gravity, as a full-fledged field theory, entirely in terms of gauge theory ingredients.
