Biography
I am a PhD researcher specializing in environmental mineralogy, with a focus on the interactions between metals and iron minerals. My aim is to address the use of iron minerals for environmental remediation highlighting my commitment to addressing global environmental challenges.This curiosity led me to pursue a PhD, where my work centered on the use of magnetite nanoparticles to recover critical metals and dissolved organic carbon (DOC) from environmental and anthropogenic waste. Through this research, I explored innovative applications of nanoscale magnetite, including metal recovery from mine waters and DOC sorption for improving drinking water quality.
During my PhD, I developed a strong expertise in synthesizing and scaling up iron-based composites and conducting batch studies under varied environmental conditions. My findings, including the removal of metals such as zinc to below detection limits, have implications for sustainable water treatment and critical metal recovery.
