My main interest subject is Number Theory: transcendental number theory, Diophantine equations, recurrent sequences, Diophantine approximation and elementar number theory.
I obtained my undergraduate and master degree in Mathematics from Universidade Federal do Ceará and doctor degree in Mathematics from Universidade de Brasília.

My preferred number is \(\log \pi = 1.14472988584940017414342735135\ldots\) which I hope to prove (at least) its irrationality.
My Erdös number is 2 (Marques\(\to\)Luca\(\to\)Erdös).
