I am an Associate Professor in the Digital Signal Processing and Image Analysis (DSB) group, which is part of the Section for Machine Learning, Department of Informatics.

I graduated from Kyung Hee University, in South Korea, and obtained my PhD working at the Image Processing Lab. I worked on facial analysis, object detection and image enhancement.  I did my Bachelor in Engineering from Universidad de San Carlos de Guatemala on Computer Science and Systems Engineering.

I'm interested in Computer Vision and Machine Learning. I work on several topics of computer vision and applied machine learning. I'm exploring the use of machine learning for a description of the world and its understanding through (mainly, but not limited to) vision sources.
