Helena Passos obtained her MSc degree in Chemical Engineering in 2012. After being awarded with a Fundação para a Ciência e Tecnologia (FCT) PhD scholarship, in June of 2017, she completed a European PhD in Chemical Engineering at the University of Aveiro. During her PhD she had additional trainees activities at Technical University of Dortmund, Germany and Tokyo University of Agriculture and Technology, Japan. Between July of 2017 and April of 2019, H. Passos was a post-doctoral researcher at CICECO – Aveiro Institute of Materials, University of Aveiro. During this period, she was involved in an international ERA-MIN project concerning the recovery of cobalt and REE from NiMH batteries recycling and in a European Research Council (ERC) Grant focused on the use of aqueous biphasic systems for the purification of egg yolk antibodies as alternative biopharmaceuticals. Currently, H. Passos is a Junior Researcher at CICECO – Aveiro Institute of Materials, University of Aveiro. Since 2012, Passos published 31 articles in international peer reviewed multidisciplinary high impact journals (ISI, h-index 12), and presented several oral and poster communications in national and international conferences.
