Leonardo F. R. Ribeiro

(Leonardo Filipe Rodrigues Ribeiro)

I'm a final-year PhD student at UKP Lab at Technical University of Darmstadt, advised by Iryna Gurevych. During my Ph.D., I work on generation models for summarization and that produce fluent text from structured data. Specifically, I focus on graph-based inputs and introduce different approaches to better represent graph structures for text generation. From June to September 2021, I worked with Markus Dreyer, Mengwen Liu and Mohit Bansal as a research intern at Amazon Alexa AI.

I'm broadly interested in the intersection of deep learning and natural language processing (NLP). My research interests include text generation, summarization, controllability and faithfulness of generation models, graph representation learning for NLP and reasoning about human and world knowledge.

I received a BS degree in Computer Engineering from the Centro Federal de Educação Tecnológica de Minas Gerais (CEFET-MG), in 2014. I studied for one year at the Universidad del País Vasco, Spain, attending classes from September 2012 until June 2013. I, then, received a Master degree in Computer and Systems Engineering from the Universidade Federal do Rio de Janeiro (COPPE/PESC/UFRJ), in 2017. My advisor was Daniel Figueiredo.
