Rafael Veras

Graduate Student

I’m currently pursuing my Doctoral degree in Computer Science. In my Master’s thesis work, I used NLP techniques to train the first empirical semantic model of passwords and demonstrated the model can be used to guess more passwords than the current approaches. I’m primarily interested in information visualization and human-computer interaction, in general. Other topics of interest include natural language processing and natural user interfaces.

I got my Bachelor’s degree from Federal University of Pará, in Belém, the main city of the Brazilian Amazon region. While in my undergraduate program, I worked in several InfoVis projects and published a few papers. I also worked in a small software company as a programmer before starting my Master’s.

Currently, I am working on this project, whose goal is to find a better method for generating overviews of arbitrary hierarchical datasets. Its preliminary results were presented as a poster at Vis 2014. To some extent, this project fits into the theme of analytical guidance in visualization, which I am excited about.
