I come from that little country in the middle of the world, Ecuador. I received my PhD at the Center for Processing Speech and Images (ESAT-PSI) of KU. Leuven under the advice of Prof. Tinne Tuytelaars and Prof. Luc de Raedt in April 2015. Earlier I received my engineering degree from Escuela Superior Politecnica del Litoral in Ecuador. During my Ph.D. I conducted research on understanding how groups of elements from the image (objects, object-parts, image regions, trajectories, etc.) interact and how the relationships between them can be exploited to improve artificial visual perception problems. This fueled my interest towards investigating exploratory/explanatory models that can identify informative intermediate representations and use them as means to justify the predictions that they make.

As part of my work I am responsible for organizing the series of seminars in the lab. Feel free to contact me if your are interested in giving a talk at KU Leuven.

A copy of my CV can be found here.

Research Interests

Context-Aware Reasoning, Model Interpretability/Explainability, Collective Classification, Relational Learning, Learning-based Representations, Gesture Recognition.

I thank the following institutions for supporting my research:
