Adjunt Professor at the School of Technology and Management of the Polytechnic Institute of Leiria, and a researcher at the Adaptive Computation (AC) Group of the Centre for Informatics and Systems of the University of Coimbra (CISUC). Concluded my PhD in 2018, and my main research interests include text classification, particularly regarding information extraction in social networks, adaptive learning in dynamic environments, classification strategies using crowdsourcing and active learning and more recently smart farming and IoT.
