Helena Freitas received her PhD in Ecology from the University of Coimbra, in collaboration with the University of Bielefeld, Germany, in 1993, and did postdoctoral studies at Stanford University, USA, between 1994 and 1996. She is Full Professor of Biodiversity and Ecology at the Department of Life Sciences of the Faculty of Sciences and Technology of the University of Coimbra since 2003, and holds the UNESCO Chair in Biodiversity and Conservation for Sustainable Development since 2014 (http://unescobiodiversitychair.uc.pt). She was Vice-Dean of the University of Coimbra between 2011 and 2015, with Institutional Relations, Museums and Sports. In 2015 she was independent candidate to the Assembly of the Republic, leading the list of the Socialist Party by the constituency of Coimbra.

Helena Freitas joined the General Council of the University of Coimbra (2009-2011), was Director of the Botanical Garden of the University of Coimbra from 2004 to 2012, having prepared and coordinated her requalification program, President of the League for the Protection of Nature (1999 (2002-2005), founder and President of the Portuguese Society of Ecology (2004-2013) and Vice- President of the European Society of Ecology (2009-2012). She is currently Coordinator of the Center for Functional Ecology - science for people and the planet (cfe.uc.pt), Scientific Coordinator of FitoLab - Phytosanitary Laboratory of the Pedro Nunes Institute (https://www.ipn.pt/ laboratory / FITOLAB), and is part of the Scientific Council of the Department of Life Sciences of the University of Coimbra. The scientific areas of specialty are related to: Ecology; Mediterranean Ecosystems; Forest and Agriculture; Ecology and Management of exotic and invasive species; Conservation of Nature, Biodiversity; Physiology of the tree; Diversity of Plants and Fungi; Tolerance to Stress and Bioremediation; Environmental policy; Bioenergy; Conservation of Nature; Microbial ecology; Ecology and Society. She coordinated or participated in several national and international projects and consortia, including the Millennium Ecosystem Assessment. Supervised or co-supervised 33 doctoral dissertations and 19 master's theses. She is the author of more than 200 indexed international scientific publications and several publications promoting and disseminating science. She publishes regularly in the national and regional press, in particular on environment, territories and society, planning and development policies based on knowledge (https://www.publico.pt/autor/helena-freitas; http: //www.industriaeambiente .pt / authors / helena-freitas /).
