Muhammad Mustafa discovered his passion for Laser spectroscopy through experimental work during his Master’s studies at the University of Engineering and Technology (UET), Lahore, Pakistan. He is a researcher at Laser & Optronic Center (LOC), UET, with over seven years of specialized experience in developing Laser-induced breakdown spectroscopy (LIBS). He continues to build comprehensive expertise in LIBS, spanning laser–matter interaction, plasma diagnostics, calibration-free and enhanced LIBS methods (CF-LIBS, EF-LIBS, NE-LIBS), and the integration of machine learning models for medical applications. He further refines his skills under the guidance of prestigious research mentors and fellows in the USA, Austria, Italy, Spain, China, and Saudi Arabia, gaining a global outlook. His long-term goal is to transfer LIBS from lab-based research to real medical diagnostic applications in hospitals and clinics.
