Born in Colombia, I am currently Fellow Researcher (Chargé de Recherche in the French system) at Mines Paris PSL Research University. Before coming to Mines Paris, I have worked as a postdoc researcher at ITWM, which is part of the Fraunhofer Institute in Germany, and at the Mathematical Department of the National University of Singapore (NUS).
In my research, I am interested in understanding and designing methods to solve problems on images, 3D cloud points and graphs. I have a preference for the method based on interactions between nonlinear operators with high geometric interpretation and those based on deep learning.
