I am a theoretical physicist working in the field of elementary particle physics. My main research interests revolve around (super)string theory, gravity and quantum field theory. More recently, I have been thinking about Artificial Intelligence and how Machine Learning algorithms can be employed to address fundamental questions in formal quantum field theory.

Research topics

• Non-perturbative dynamics and duality in Quantum Field Theory

• Supersymmetry and supersymmetry breaking

• Machine learning applications to Quantum Field Theory

• Holographic dualities

• String theory

• Black Holes

BootSTOP: a STochastic OPtimizer for Conformal Bootstrap studies  - GitHub link and a dedicated website link 
(Release 2 is now available. It includes the modifications of the improved truncation methods with tail approximation, more pre-generated conformal blocks and access to all the PyGMO algorithms.)
