Postgraduate Research Student

Room Number: Mathematical Sciences Building, Room: MB-402


Diego is a 4th year PhD student under the supervision of Dr. Juan A. Valiente Kroon and part of the Geometry and Analysis group at Queen Mary University of London. Previously, he completed his undergraduate studies in Physics at UNAM (Mexico) and obtained a masters degree in Astrophysics at the same university where he studied some cosmological models under an extended theory of gravity.

His current research focuses on the mathematical aspects of the General Theory of Relativity using conformal methods. Currently, he is carrying out investigations about the construction of anti-de Sitter-like spacetimes with a tracefree matter component. In this context, the allowed type of boundary data on the conformal boundary represent an interesting problem. He also has analysed the so-called Conformal Einstein Field Equations and their properties. Previously, he studied problems related to the existence of continuous symmetries on the aforementioned spacetimes.
