I am a researcher with the 2D4H – Secondary Data for Healthcare Research group at CINTESIS (cintesis.eu). I completed my PhD in clinical and health services research at the Faculty of Medicine, University of Porto. I received my Licentiate and Master’s degree in Electrical Engineering, specializing in Telecommunications, Computer Networks, and Electronics from the Faculty of Engineering, University of Porto, and I earned a Master's degree in Medical Informatics from the Faculty of Medicine, University of Porto. Over the last 12 years, my focus has been on data analytics, machine learning, data quality, and data visualization in healthcare. I have been involved in analyzing large datasets for several projects targeting specific diseases, such as diabetes and tuberculosis. Additionally, my work encompasses performance, management, and clinical indicators within hospital and emergency care settings. I am passionate about different areas of knowledge and solving problems using data. I am at my best when working in a multidisciplinary team.
