Maria J. Sampaio graduated in Chemical and Biological Engineering at School of Technology and Management at Polytechnic Institute of Bragança (ESTIG-IPB, Portugal) in 2008. In 2009 Maria J. Sampaio earned a research felloship at Faculty of Engineering of the University of Porto (FEUP, Portugal), Laboratory of Catalysis and Materials (LCM, Associate Laboratory LSRE-LCM) to work during two years in the development of carbon-based materials for wastewater treatment using heterogeneous photocatalysis.
In 2012 she earned a Fundacão para a Ciência e a Tecnologia (FCT) doctoral grant and started her PhD studies at LCM-LSRE. During her PhD studies she was a visinting scholar in two Universities abroad, one at Engineering Research Center at Engineering Research Center Cincinnati, USA) and other at Laboratoire de Chimie de Coordination (Toulouse, France). Maria J. Sampaio completed her European PhD degree in Chemical and Biological Engineering by University of Porto in 2016. She received the european PhD Certificate on Advanced Oxidation Processes (AOPs) Certificate for the doctoral thesis entitled “Nanostructured architectures based on metal oxides with direct wide band-gap for the engineering of photocatalytic reactions”. Currently, she is working in a research project in the area of synthesis of fine chemical products with high-value using photocatalytic technologies.
