Noureddine Melikechi

Noureddine Melikechi is a High Senior Professor at Delaware State University, where he leads research at the intersection of laser science, materials science, and health diagnostics. His work centers on laser-induced breakdown spectroscopy (LIBS), machine learning, and planetary science, with recent breakthroughs including the development of tag-LIBS and nanoparticle-enhanced LIBS (NELIBS) to boost biomarker detection sensitivity for diseases such as Alzheimer's and SARS-CoV-2. His 2026 publications in *Nature Communications* and *Research Square* explore pathwise false discovery control in local graph estimation and blood metal profiling via LIBS, respectively. Melikechi also applies LIBS to Martian atmospheric conditions and jewelry rock discrimination using convolutional LSTM algorithms, advancing both space exploration and forensic applications. His interdisciplinary collaborations span atomic spectroscopy, health sciences, and machine learning, cementing his reputation as a pioneer in translating spectroscopic techniques into clinical and planetary tools.
