About
I am a theoretical physicist at the Federal University of Santa Catarina (UFSC), Brazil, specializing in General Relativity and Modified Gravity. My research focuses on the classical and quantum dynamics of particles in curved spacetime, with particular emphasis on black hole physics, compact star structure, and extensions of General Relativity.
Over the past decade I have published more than 40 papers in journals including Physical Review D, European Physical Journal C, Classical and Quantum Gravity, and Annals of Physics. I am also interested in Artificial Intelligence and its applications to scientific research and data analysis.
Feel free to reach out for discussions or collaborations.
Research areas
Black hole physics — Kiselev, regular, and rotating black holes in modified gravity (f(R,T), Rastall, Rainbow gravity). Thermodynamics, shadows, acoustic analogues, and the Rastall-Rainbow unification.
Compact stars — Neutron stars, quark stars, and protoneutron stars in extended gravity theories. TOV and generalized TOV equations, Bayesian astrophysical constraints, hyperons and Δ resonances, equations of state.
Quantum mechanics in curved spacetime — Scalar and fermionic fields in cosmic string backgrounds, topological defects, Melvin universe, and non-inertial effects. Klein-Gordon oscillator in nontrivial spacetimes.
Modified and extended gravity — f(R,T), f(T,T), Rastall, Rainbow gravity, and Finsler geometry extensions. Theoretical formulation and astrophysical signatures.

Equations I find beautiful
Einstein field equations
\[G_{\mu\nu} + \Lambda g_{\mu\nu} = 8\pi G\, T_{\mu\nu}\]The foundation of General Relativity: spacetime geometry on the left, energy-matter content on the right. Every black hole and every compact star I study lives inside these equations.
Tolman–Oppenheimer–Volkoff equation
\[\frac{dP}{dr} = -\frac{(\varepsilon + P)(M + 4\pi r^3 P)}{r(r - 2M)}\]The stellar structure equation in full GR — governs the interior of neutron stars, quark stars, and every compact object I model. A relativistic correction to Newtonian hydrostatics that changes everything at high densities.
Klein–Gordon equation in curved spacetime
\[\frac{1}{\sqrt{-g}}\, \partial_\mu \!\left(\sqrt{-g}\, g^{\mu\nu} \partial_\nu \Phi\right) - m^2 \Phi = 0\]The simplest relativistic wave equation generalized to any curved background. The starting point for all my work on quantum dynamics in cosmic string spacetimes, topological defects, and Rainbow gravity.
Maxwell’s equations (covariant form)
\[\nabla_\mu F^{\mu\nu} = J^\nu \qquad \nabla_{[\mu} F_{\nu\rho]} = 0\]The most elegant formulation of electromagnetism — two equations that say everything. The Melvin universe, where I study charged fields, is entirely built from solutions to these.
