Abstract: Warm inflation provides an attractive solution to the so-called eta-problem that generically plagues supergravity and string theory models, with additional dissipation damping the inflaton's motion and simultaneously producing radiation during inflation.
Abstract: n-DBI gravity is a gravitational theory introduced in arXiv:1109.1468[hep-th], motivated by Dirac-Born-Infeld type conformal scalar theory and designed to yield non-eternal inflation spontaneously. I explain that any solution of Einstein gravity with a particular curvature property is a solution of n-DBI gravity.
Abstract: The knowledge of the Universe is essentially based on the theory of general relativity (GR). If from one hand, solar system data is in excellent agreement to the theory, available cosmological evidence on the other, is consistent with GR provided one assumes the existence of dark energy and dark matter.
Abstract: One of the most interesting and current phenomenological extensions of General Relativity is the so-called f(R) class of theories; a natural generalization of this includes an explicit non-minimal coupling between matter and curvature.
Some of my research interests are:
o Black hole physics
o General relativity, numerical relativity and gravitational radiation
o Supergravity, string theories and the gauge/gravity duality
o Differential geometry
o Casimir effect and quantum field theory
o Cosmology and inflationary models

Some distinctions/awards:
Gr@v is a team of researchers, based at the Mathematics and Physics Department of Aveiro University, Portugal, working on strong gravity and high energy physics. The group was established in 2010. In January 2015 Gr@v integrated the FCT funded CIDMA research unit (UIDB/04106/2020 and UIDP/04106/2020), as the Gravitational Geometry and Dynamics research group. In January 2025 colleagues from the U. Algarve joined CIDMA and the group.
