Tatiana Ferreira is a chemist at the Federal University of Rio de Janeiro---UFRJ, Brazil, with an M.Sc. and Ph.D. in the Engineering of Chemical and Biochemical Processes from the School of Chemistry (UFRJ, Brazil). She is a Professor at the Department of Organic Processes in the School of Chemistry (UFRJ, Brazil). Her research focuses on the valorization of renewable resources, with an emphasis on waste and by-product use, industrial biotechnology, and biorefinery development. Her research approach involves the bioconversion of renewable resources to products, such as 2,3-butanediol, 1,3-propanediol, ethanol, butanol, and organic acids, using anaerobic bacteria. Special focus is given to the evaluation of the sustainability of biorefinery concepts utilizing renewable resources as feedstocks to produce bio-based chemicals, biofuels, and value-added products.
