    Zhaoshan Chang is the Charles Fogarty Endowed Chair and Professor in Economic Geology at Colorado School of Mines (CSM). He worked at various universities before, including Peking University, China (1997-2000); Washington State University, USA (2004); CODES, University of Tasmania (2004-2011), and EGRU (Economic Geology Research Centre), James Cook University (2011-2018). He was the Director of EGRU from 2012 to 2018 before joining CSM. Zhaoshan has studied a wide spectrum of mineral systems, including skarn-, porphyry-, epithermal-, IOCG- deposits, W-Sn, and sediment-hosted gold deposits in 19 countries. He works closely with the mineral industry on exploration-oriented research projects, looking for far field signals, discriminators and zoning patterns in mineralogy, textures, spectral features, whole rock and mineral geochemistry, and isotopic compositions that can be directly used in exploration. He also works on ore-forming processes and ore controlling factors, magma fertility, regional metallogenesis, and LA-ICP-MS methodology (dating; mineral trace element analysis; isotope composition analysis). His research mainly involves field investigation and drill core logging, petrography, Short Wavelength Infra-Red (SWIR) spectral analysis, whole rock and mineral chemistry, textural imaging using various techniques (LA-ICP-MS, PIXE, CL, BSE, microprobe), geochronology, fluid inclusion thermometry and composition, various isotope systems (O-H-S-C; Cu-Zn-Fe; Sr, Hf), and LA-ICP-MS techniques. He runs a LA-ICP-MS/MS (Agilent 8900) lab at CSM, plus a fluid inclusion lab and a SWIR instrument.
