I’m a PhD in Computer Science from Department of Computer Science of the University of Chile. My research interests are Information Visualization and Data Mining.

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 STEM. We aim to show to our girls that computer science is super fun (:
