I'm glad to receive another invitation from AusIMM and Stuart Nicol for a webinar. At this time, titled "Electrochemical-based separation techniques in hydrometallurgical processing," we will delve into the principles and applications of electrochemical techniques, highlighting their advantages over other separation methods in terms of efficiency, selectivity, and environmental sustainability in hydrometallurgical applications (mining and recycling).
The webinar will be on March 04, 2025 at 12.00pm – 1.00pm (UTC+11:00). Everyone is invited. Join us to discover how these cutting-edge techniques can optimize resource recovery and contribute to a more sustainable future.
I'm glad to be elected as Diversity, Equity, and Inclusion (DEI-Human Affairs) Chair of the Postdoctoral Association at the Massachusetts Institute of Technology. The MIT Postdoctoral Association (PDA) is a postdoc-led organization to provide support for over 1500 postdoctoral trainees appointed in 50 departments at MIT. The PDA is structured according to the guidelines provided by the National Postdoctoral Association (NPA) for forming and maintaining a PDA and is supported by the MIT Office of the Vice President for Research (VPR).
Standing Committees are responsible for fulfilling a specific set of responsibilities consistent with the MIT PDA mission. The DEI Committee shall:
Encourage fair treatment, prevent and eliminate discrimination, and foster mutual understanding and respect among all postdocs;
Direct postdocs to resources for DE&I at MIT;
Advocate for changes alongside the Advocacy Committee to promote DE&I for postdocs at MIT;
Emphasize the role postdocs play in DE&I within academia broadly, and support training and resources that allow postdocs to promote DE&I after their time at MIT;
Support programs for postdocs and postdoc groups related to the goals and missions of the Human Affairs Committee (health & wellness, diversity & inclusion, etc.).
It is a great honor for the first time being on the list of a percentile rank of 2% or above in my research field (Chemical Engineering, Materials Science, Sustainable Mining). This achievement results from a lot of work in different institutions (as Universidade de São Paulo, The University of British Columbia, The University of Queensland, the University of Brescia, Stanford University, and now the Massachusetts Institute of Technology).
I completely understand all the pros and cons of this list, and it motivates me to drive better academic studies in partnership with industries and government stakeholders. Beyond that, I'm always looking to improve the quality of my research, aiming for high-impact journals and transforming science into reality (and industrial processes and business). For me, academic work must always look at improvements, and, as engineers and applied science, we should transform molecular reactions into large-scale processes to transform our society into a green future.

Patent of battery recycling process developed at the University of Sao Paulo was published worldwide (WO2024178482A1). This project aimed at the designing of hydrometallurgical process for LI-ion battery recycling from electric vehicles. The novelty here proposes the use of electrochemical separation, as well as solvent extraction and ozone precipitation to obtain high-pure products. Beyond that, the innovation proposes recycling methods of different cathode materials - LCO (LiCoO2), NCA (LiNiCOAlO2), LMO (LiMnO2 or LiMn2O4), NMC (LiNixMnyCozO2), and LMO-NMC (LiNiCoAlO2-LiNixMnyCozO2)) - and battery types - prismatic, cylindrical and pouch. Link for the patent.
In September 2nd, I did a presentation at Hydrometallurgy Conference 2024, "Hydrometallurgy for the Future" organized by SAIMM - The Southern African Institute of Mining and Metallurgy and sponsed by CMS Solutions and with grateful collaboration of Mintek. The title of the presentation was "Challenges in the separation of critical metals by hydrometallurgy."
In August/2024, it was also organized the 2nd Battery Materials Conference that I had the opportunity to be invited for a talk titled "Recovering critical raw materials from spent Li-ion batteries through hydrometallurgical process: trends and new technologies."
I’m happy to share that I’m starting a new position as Postdoctoral Associate at MIT Department of Materials Science and Engineering (DMSE) under the supervision of Prof. Yet-Ming Chiang. The goal of this project is the development of electrochemical system for separation of critical raw materails from mining waste.
In July/2024, I attended the RELiTE 2024 conference by invitation to give a presentation. This invitation comes from Prof. Kerstin Forsberg (KTH), Prof. Alexandre Chagnes (University of Lorraine) and Prof. Victoria Flexer (CONICET). I delivered my presentation on the results obtained in my postdoc work at Stanford under the supervision of Prof. William Tarpeh. This project, among others (as presented in the photo above), focused on Li extraction from brine by membrane-based electrochemical separation.
In May/2024, I had the opportunity to present my work developed at Stanford University in the Department of Chemical Engineering at ECS 2024. The project aimed to study the co-ions effect in Li extraction brine in a membrane-based electrochemical separation system.
In addition, Orisa Coombs (PhD student supervised by Prof. William Tarpeh/Stanford) presented her work about using solar panels in ammonia stripping (membrane-based electrochemical separation) which I had the opportunity to collaborate.
In March/2024, I participated in the TMS 2025 conference for oral presentation of three works:
Development of a Hydrometallurgical Process to Obtain High-Purity Alumina Using Bauxite
Separation of Critical Metals Using Supported Liquid Membranes PTFE-Cyanex 272
LAREX-Tupy Process: Recycling of Li-Ion Batteries from Electric Vehicles by Hydrometallurgical Route Towards Circular Economy
At this conference, I was chosen as Secretary and JOM Editorial Board of the Recycling and Environmental Technologies Committee for the next 2 years.
We deposited three patents of the process developed for recycling of Li-ion batteries using hydrometallurgy. The innovation comprises in physical treatment for separation of case, foils and polymeric fractions, separation of electrolytes, and acid leaching of the black mass. The metals in leach solution was further separated by solvent extraction, precipitation and electrodialysis to obtain high-pure products for several applications, including new batteries.
I'm glad to announce that I started my new position at Stanford University in the Department of Chemical Engineering. I'm joining the Tarpeh Lab under the supervision of Prof. William Tarpeh to work in membrane separation and electrodialysis to recover critical raw materials from different sources.
This position starts in June/2023 for 1 year.
I was honored to receive the prize of the best PhD thesis of the University of Sao Paulo in Environmental Sustainability. The University of Sao Paulo (USP) is the most important university in Latin America (#1). The thesis was focused on developing an extractive process of Sc from bauxite residue in light of sustainable development. The residue is generated in a Brazilian process for alumina production. Challenges in silica gel formation during acid leaching reaction were studied, understood, and overcome for further Sc extraction. Complexing formations for Sc extraction towards economic feasibility were studied using phosphinic-based extractants.
This thesis was developed between 2019-2021 (30 months) and published 7 highly-cited papers in scientific journals, supervision of undergrad and graduate students and publishing their papers.
After defending my thesis and starting a postdoc position, I had the opportunity to teach as a professor in two different graduate courses. Urban and Industrial Solid Waste is offered to graduate students of the University of Sao Paulo, including department as engineering, education, health, and STEM.
In addition, our new discipline proposed Recovery of chemical compounds in aqueous solutions by membranes was approved by the Department of Chemical Engineering and is offered to all graduate students of the University of Sao Paulo focused on engineering students interested in membrane separation.
