I’m a postdoc researcher at the ILDA team at Inria.

I have a PhD in Computer Science from the Department of Computer Science of the University of Chile. My research interests are Information Visualization and Data Mining, mainly focused on spatio temporal data.

I love teaching and I believe learning should be for anyone. Because of this, I’m part of Niñas Pro(gramadoras), an initiative that motivate girls to learn to program to reduce the gender gap in STEAM. We aim to show to our girls that computer science is super fun (:
