I am a professor and researcher in Economic Geology. Mineral exploration, mining environmental assessment and feasibility studies are also my field of interest. I am basically teaching economic geology and related subjects for undergraduate, master and doctor program at Department of Geological Engineering, Faculty of Engineering, Universitas Gadjah Mada. I occasionally serve the mining companies, government and other stake-holders for various professional and scientific works related to geology, exploration and mining. I am enjoying my academic life!:)
