Augusto Sagnotti (born 1955) is an Italian theoretical physicist at Scuola Normale (since 2005).

Biography

Sagnotti earned a

Caltech in 1983 (advisor: John H. Schwarz). He was Post-Doctoral Fellow at Caltech (1983–84) and Miller Research Fellow at U.C. Berkeley (1984–86).[citation needed
]

Sagnotti was Junior Faculty at the

]

Sagnotti's main contribution to physics is perhaps the analysis of the

open and closed strings, non supersymmetric but free of tachyons.[11][12] He has worked extensively on higher spins, arriving at a geometric formulation of their free field equations in terms of higher-spin curvatures.[13]

More recently, Sagnotti has been working on the proposal of a possible link between "

inflationary phase, and on the exploration of some of its possible imprints on the CMB,[18] in particular, the proposal that the low value of the CMB quadrupole[19] and a first peak for l ~5[20]
be a manifestation of the onset of the inflationary phase.

Awards and honors

Sagnotti received the Carosio Prize from the University of Rome “La Sapienza” in 1979, a Miller Fellowship from U.C. Berkeley in 1984, shared with Massimo Bianchi the 1994 SIGRAV Prize of the Italian Society for General Relativity and Gravitation,[21] and received the Margherita Hack Prize for Science in 2014 for his work on the quantization of gravity and a Humboldt Research Award in 2018.[22] He was also Andrejewski Lecturer at Humboldt Universitat in Berlin in 1999.
