I am an Assistant Professor of Computer Science at the University of Colorado Boulder, where I lead the Boulder Language and Social Technologies group. Before joining CU, I was a Postdoctoral Researcher at Microsoft Research NYC. I completed my PhD in Computer Science at Purdue University, and my BSc. in Computer Science and Engineering at the Universidad Simon Bolivar in Caracas, Venezuela, where I was born and raised.
I primarily work on Natural Language Processing and Machine Learning. I am mostly interested in the integration of structured knowledge and statistical models, and in the relationship between language and social systems. Most of my previous work has focused on structured prediction and (deep) statistical relational learning, and their application for analyzing public discourse, argumentation and narratives. I am a strong believer in interdisciplinary, collaborative work. I actively collaborate with researchers in linguistics, security, human-computer interaction, bioinformatics, and the behavioral and social sciences.
