Susana Brás is an Assistant Professor at the Department of Electronics, Telecommunications, and Informatics and a researcher at the Institute of Electronics and Informatics Engineering of Aveiro (IEETA), University of Aveiro, Portugal. She has a background in Applied Mathematics, with a Ph.D. in Biomedical Sciences, and she completed a postdoctoral research in Computer Sciences, mainly focused on the data science field. Her main research goal is the development of environments adapted to the person. To accomplish such a goal, she studied models able to quantitatively describe patterns, mainly focused on parameter-free data mining, information theory models, and machine learning. Until now, she was dedicated to studying the person and his/her reactions to society and specific situations (affective computing). Notwithstanding, she is now also interested in studying the environment where the person is inserted to adjust the context to the person's needs to achieve a better life quality. The description of such context will lead to constraints associated with class imbalance, noise, artifacts, and missing values, topics already studied by her research team. She supervised several master and Ph.D. students. She gave several invited talks in diverse contexts and interviews in the general media. S. Brás is committed to advancing clear and impactful scientific communication. Also, as a personal and professional interest, she is dedicated to promoting gender equity in tech, integrating communities like Geek Girls Portugal.
