About me

I am the current Maria Victoria Bernido-Carpio Research Fellow of the Research Center for Theoretical Physics in Jagna Bohol, Philippines. I obtained by PhD in Mathematics at Mindanao State University, Iligan Institute of Technology (MSU-IIT) in the Philippines under the supervision of Jocelyn Vilela of MSU-IIT and Roozbeh Hazrat of Western Sydney University, Australia where had a 1-year research fellowship.

Broadly, my research lies in the areas of Leavitt Path Algebras and Monoids with group action. In particular, I’m interested in answering questions about the relationship of representation of the talented monoid and the representation of the corresponding Leavitt Path Algebra, especially the graded isomorphism conjecture. Indeed, as of now, in all of my research, I make use of a graded version of the graph monoid, the so-called talented monoid. But I am open to learn new techniques and methods. You can read more about my work in my current research section.
