Dr. Maria Emilia Fernandez is currently an Associate Researcher at Photoreactors Engineering and Environmental Technologies Group, Instituto de Desarrollo Tecnológico para la Industria Química (INTEC) - CONICET- UNL, Argentina (2017-present). She obtained a Bachelor in Biotechnology at Universidad Nacional del Litoral (UNL), Argentina (2008), and a PhD in Industrial Chemistry at Universidad de Buenos Aires (UBA), Argentina (2013). She has broad experience in adsorption/biosorption processes (batch and continuous mode) and its modelling. Physicochemical, textural and morphological characterization of sorbents developed from lignocellulosic residues, hydrochars and graphene oxide in polymeric matrices. Characterization and modelling of pesticides adsorption and degradation in biopurification systems (biobeds and biofilters) with and without the aid of earthworms. Her work has been published as articles in international scientific journals, chapter books and national/international conference proceedings. She has been reviewer for R&D projects and for several peer-review journals. Her main interests are the biopurification systems optimization to reduce water and soil contamination, with the focus on contaminants adsorption/degradation, and the biotechnological use of organisms for decontamination as well.
