José Eduardo Ochoa Luna's homepage

I hold a Ph.D. in Science (Engineering School at the University of São Paulo, Brazil). Currently, I am an assistant professor at the Universidad Católica San Pablo (undergraduate and graduate levels). Most of my research work was conducted at the Decision Making Lab under supervision of the Prof. Fabio Cozman.

My research interests include but are not limited to Uncertainty in Artificial Intelligence, Knowledge Representation, Machine Learning and Natural Language Processing. My current work focuses on Neural NLP. My previous work has focused the combination of Probabilistic and Logics, i.e., Probabilistic Logic.

Short biography

I was born in Arequipa, a southern city of Perú, there I got a Bsc. in Systems Engineering at the Universidad Nacional de San Agustin. Then I moved to Campo Grande, Brazil where I got a Msc. in Computer Science at the Federal University of Mato Grosso do Sul.

From 2006 to 2012, I lived in São Paulo, Brazil, there I got a PhD in science at the University of São Paulo. Since 2013, I am living in Perú where I am an assistant professor at the Universidad Católica San Pablo (from 2013 until 2016 I was a lecturer at Universidad Nacional San Agustin).
