The twistor space had shown to be a powerful tool to understand the scattering amplitudes in N=4 d=4 Super-Yang-Mills theory. In this project, we intend to utilize a similar approach in order to obtain a better understanding at loop level of N=8 d=4 supergravity as well as of N=1 d=10 SYM theory, which can be the key to find the origin of the pure spinor formalism.
