I am a PhD student at Departament of Mathematics of Universidade Federal de Minas Gerais (UFMG), Brazil.
I am mainly interested in applying (higher) categorical theory to Physics and Mathematics, and also in some aspects of differential geometry. Previously I was involved with mathematical aspects of Astrophysics.
The best way to contact me is through yurixm@ufmg.br.
I am co-founder of a research group on mathematical-physics and categorification called Math-Phys-Cat Group.

On an axiomatization proposal to the notion of strong emergence between Lagrangian field theories:
A generalized and simplified version of the above work:
On a functorial extension of Feynman rules from Feynman graphs to structured hypergraphs.
For the complete list, see here.
On an introduction to (algebraic) topology and differential geometry aiming the study of general spherically symmetric black holes (in Brazilian portuguese):
On an introduction to abstract homotopy theory by means of model categories and (infinity,1)-categories (in Brazilian Portuguese):

On a vertical categorification of Lie algebras (called Lie algebroidal categories) and a connection with Lie algebroids. A priori the Lie algebroidal categories differs from Lie 2-algebras of Baez-Crans, but further investigations are needed.
Currently I am (co)advising three master students (joint Rodney Josué Biezuner). For past advising, see here.
