Helena Passos earned her MSc in Chemical Engineering from the University of Aveiro (UA) in 2012. With a PhD grant from the Portuguese Foundation for Science and Technology, she completed her PhD in Chemical Engineering at UA in 2017. From 2017 to 2019, she worked as a post-doctoral researcher in a European Research Council (ERC) project focusing on the use of aqueous biphasic systems (ABS) for purifying egg yolk antibodies as alternative biopharmaceuticals, and in an international ERA-MIN project dedicated to the recovery of cobalt and rare earth elements from nickel metal hydride (NiMH) batteries. In 2019, she was awarded a Junior Researcher position by FCT (Scientific Employment Stimulus - Individual Call 2017) to develop novel and sustainable processes using alternative solvents for recovering and recycling critical raw materials from electronic waste.
