About me


Welcome to my webpage!

I am Pilar and my Chihuahua's name is Ada.

I am currently a Postdoc in the Algorithms Research Group at Université Libre de Bruxelles in Belgium, hosted by John Iacono.

I finished my Ph.D at Universitat Politècnica de Catalunya and Carleton University, under the supervision of Prosenjit Bose and Rodrigo Silveira.

My main research interests are Graph Theory, Computational Geometry, Combinatorics and Algorithms.
