Helena Passos obtained her MSc degree in Chemical Engineering in 2012. After being awarded with a PhD grant from the Portuguese Foundation for Science and Technology, she completed her PhD in Chemical Engineering at the University of Aveiro in June of 2017. During the PhD, Helena Passos had additional trainees activities at Technical University of Dortmund, Germany and Tokyo University of Agriculture and Technology, Japan. After, she worked as a post-doctoral researcher in an international ERA-MIN project concerning the recovery of cobalt and REE from NiMH batteries recycling and in a European Research Council project, the “IgYPurTech”, focused on the use of aqueous biphasic systems for the purification of egg yolk antibodies as alternative biopharmaceuticals. Currently, Helena Passos is a Researcher (CEEC IND 2017) at CICECO, working in the development of novel and sustainable processes for the recovery and recycling of critical metals from waste streams.

Helena Passos has published 35 articles in international peer reviewed multidisciplinary high impact journals (+1100 citations, h-index 16 (Scopus)). Moreover, she has contributed with +100 oral and posters communications and 1 plenary lecture in national and international conferences and meetings.
