I received my BMath degree from Universidad Central de Venezuela, in my hometown Caracas, where I also worked as an Instructor teaching undergraduate maths courses. Later on, I completed my PhD in pure mathematics at the University of Melbourne under the supervision of Arun Ram and Craig Westerland.

Before joining SUTD, I worked as a Postdoctoral Fellow and Assistant Professor in the Department of Mathematics at the University of Western Ontario, and as a software developer for an independent project in London, UK.

Research Interests

My research to date sits at the interface of algebraic combinatorics and homotopy theory, more specifically in Schubert calculus problems. For my bachelor’s thesis I worked on topics of differential geometry and algebraic topology in the form of de Rham cohomology. I am currently also interested in the pedagogy of mathematics and exploring areas of applied maths.
