Biography
I graduated in Translation Studies (German-Portuguese) in 2006, finished my Master Dissertation in 2009 and my Doctoral Thesis in 2015 at the Institute of Linguistics, Universidade Federal do Rio Grande do Sul (UFRGS). During this time, I also took part in a one-year doctoral stage at the Laboratoire d'Informatique de Grenoble in 2012-2013.
After my PhD, I have developed two post-doctoral researches in Natural Language Processing and in Computational Linguistics. The first one at the Institute of Informatics, UFRGS, from 2015 to 2016, and the second one at the Centre de traitement automatic du langage, Université catholique de Louvain, from 2016 to 2018.
In 2019, I enjoyed a time dedicated to translation as a freelancer in Brazil, before joining the Centre for Translation Studies, University of Surrey, at the end of the year.
Along these years, I always dedicated at least a part of the time to professional translation (English / French / German > Portuguese) and text proofing (English / Portuguese).

Research projects
2018 - Current. Associate Researcher
This project deals with textual and terminological accessibility, mainly focusing on the process of producing scientific texts that can be understood by laymen and people with low literacy skills, especially in a health care environment.
2016 - 2018. Post-doctoral Researcher
Language learning is a process which requires focus and immersion in the target language. With regards to e-learning, in which the language learner is much more autonomous in their language learning process, having an immersive virtual platform that enables the learner to pursue his or her own goals is a challenge to be reckoned with. In this scenario, it is important that the platform offers both ready-to-use instruments and adaptive resources that can recognize user-developed or user-prompted materials. In this way the learner is not completely attached to the predeveloped material and can focus on their own interests. Distance learning is a flexible solution for coping with the extreme diversity of language learners interested in vocational training. All this calls for the integration of Artificial Intelligence tools and advanced language technologies. In short, the learning platform needs to become "smarter". This project inserts itself in this scenario via a partnership between the Catholic University of Louvain, specifically the Centre de traitement automatique du langage (CENTAL), and Altissia, an enterprise dedicated to e-learning that handles Erasmus+ Online Linguistic Support (http://erasmusplusols.eu/).
2014 - 2016. Post-doctoral Researcher
The goal of this project is to investigate and develop techniques, resources and tools for automatic text simplification. The idea is to rewrite texts making them more accessible and easier to understand to a larger audience. Our focus is in lexical simplification, where more difficult words are replaced by more familiar synonyms, and we are interested in lexical simplification of complex expressions (such as compound nouns like brain teaser, access road, nut case) which require a high degree of precision to maintain the original meaning and result in a natural and readable alternative.
Our target groups include children as first or second language learners, and texts in both Brazilian Portuguese and English. The aim is to help reduce the literacy deficit that is an unfortunate reality of a large part of the Brazilian population, by means of resources and tools that facilitate the understanding of a text.
The project Simplification of Complex Expressions is funded by Samsung Eletrônica da Amazônia Ltda. under the terms of Brazilian federal law No. 8.248/91

Publications
This paper presents MedSimples, an authoring tool that combines Natural Language Processing, Corpus Linguistics and Terminologyto help writers to convert health-related information into a more accessible version for people with low literacy skills. MedSimplesapplies parsing methods associated with lexical resources to automatically evaluate a text and present simplification suggestions thatare more suitable for the target audience. Using the suggestions provided by the tool, the author can adapt the original text and makeit more accessible. The focus of MedSimples lies on texts for special purposes, so that it not only deals with general vocabulary, butalso with specialized terms. The tool is currently under development, but an online working prototype exists and can be tested freely.An assessment of MedSimples was carried out aiming at evaluating its current performance with some promising results, especially forinforming the future developments that are planned for the tool.
