Resource Recovery Researcher @ SNU | Hydrometallurgy | Rare Earth Element (REE) Extraction & Battery Material Recycling

Profile Summary

I am doing research at Seoul National University focused on developing green hydrometallurgical processes for the circular economy, specifically targeting the recovery of critical raw materials. My work involves the selective extraction of Rare Earth Elements (REE) from NdFeB magnets using modified Deep Eutectic Solvents (DES), to optimize leaching efficiency and selectivity. Parallel to this, I am doing research on Direct Lithium Extraction (DLE) from brine using electrochemical methods and battery-grade materials, specifically focusing on the performance of modified Lithium Iron Phosphate (LFP) under controlled calcination conditions. Through these projects, I have developed technical proficiency in materials characterization and electrochemical analysis, including the interpretation of ICP data, XRD, FTIR, and UV-Vis spectra, as well as the analysis of potentiodynamic polarization curves for metal recovery applications. 
Additionally, I am fluent in Arabic, French, English, and Korean, allowing me to offer specialized technical translation and cross-border communication support for international research collaborations and industry reports.
