Hassan is a geologist with more than 10 years of research and work experience in exploration geology and mining. He spent two years (2010-2011) researching iron oxide ore deposits in Central Iran. From 2012 to 2017, Hassan taught courses such as economic geology, surveying, field geology at Payame-Noor University of Iran. He also took part in mining projects for the Iranian Mining Engineering Organization. More recently, as part of his Ph.D. study, he applied U-Pb and Ar-Ar geochronology, mineral geochemistry, and isotopic geochemistry techniques to examine northern Appalachian gold systems and deposits in southern New Brunswick. He has applied diverse geochronological and geochemical analytical devices such micro X-ray fluorescence (µ-XRF), Scanning Electron Microscopy (SEM), Electron Microprobe (EMP), and Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS) to his work, and used portable XRF devices for in-situ real-time geochemical analysis.
