Biography

Alfredo is a Junior Fellow at the Harvard Society of Fellows. His research lies at the crossroads between quantum theory and classical gravity. In particular, he is adapting novel techniques from the S-Matrix program to the study of classical solutions in general relativity such as those describing spinning black holes, a correspondence that also sheds light on the puzzle of higher-spin particles. He is currently interested in observational signatures of these classical processes, which may be measured via gravitational waves such as the ones to be detected by LIGO/LISA, but also through electromagnetic radiation. Furthermore, he is studying the asymptotic structure of spacetime and its connection to the infrared problem of quantum theory, as well as novel geometrical structures underlying scattering amplitudes in a variety of theories.
