About me
Dr. Azhar Shaikh is an accomplished mantle petrologist interested in the petrogenesis of diamond-delivering magmas, including kimberlites and lamproites, and their mantle cargo. He employs advanced in-situ mineral chemical analysis techniques such as Electron Probe Micro-Analysis (EPMA), Laser Raman Spectroscopy, and Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICPMS) to investigate the chemical and thermal evolution of deep cratonic roots. Dr. Shaikh's research interest has recently expanded to encompass the mineral chemistry of basalts and other mafic to ultramafic rock types. He holds a Ph.D. from the Indian Institute of Technology (IIT) Bombay, where his doctoral research was focused on the mineralogy of diamondiferous kimberlites in southern India. He earned his M.Sc. in Geology from the Government Institute of Science, Aurangabad, graduating in 2012 with the distinction of the University Gold Medal.
