About Research

About

I am a PhD candidate in Chemical Engineering at the Norwegian University of Science and Technology (NTNU), affiliated with FME Battery. My research focuses on the development of sustainable and economically viable processes for lithium-ion battery recycling, with emphasis on black mass processing and the recovery of critical materials through scalable process engineering approaches.

I hold a BSc in Chemical Engineering from the Universidad Mayor de San Simón (Bolivia) and an MSc in Advanced Chemical Engineering from the University of Leeds (UK). My background combines industrial and academic experience across lithium extraction, process optimization, and scale-up of hydrometallurgical systems.

Prior to my PhD, I worked on lithium production from brines at the Salar de Uyuni, contributing to process development and optimization of lithium carbonate production, including crystallization modelling, mass balance simulation of solar evaporation ponds, and pilot-scale implementation. My work also included the development of adsorbent materials for direct lithium extraction, evaluation of lithium hydroxide production via causticization, and valorization of by-products such as potassium sulfate. In parallel, I have teaching experience in chemical engineering subjects including reactor design, transport phenomena, plant design, and material and energy balances.

Research

My research is conducted at the Norwegian University of Science and Technology (NTNU) in affiliation with FME Battery. It focuses on the development of sustainable and economically viable processes for lithium-ion battery recycling, with particular emphasis on the processing of black mass. I investigate recovery and separation strategies for critical materials using hydrometallurgical and process engineering approaches, aiming to enable scalable solutions for circular battery value chains.
