Vratislav HuraiVratislav Hurai obtained his master's degree in mineralogy, geochemistry and economic geology (1979), his PhD. (1989), and his Habilitation (2003) at Comenius University in Bratislava, where he worked in 1980-1994 and 2001-2006 in various full-time psitions and till 2012 under part-time contracts. In 1994-2000, he joined the Laboratory of Isotope Geology at the Geological Survey of Slovak Republic in Bratislava. Since 2006, he is a senior researcher at the Geological Institute of Slovak Academy of Sciences, where he received his DrSc. degree in 2009. In 1990-1991 and 1996 he was a post-doctoral research fellow of the Alexander von Humboldt Foundation at the Georg-August University of Göttingen in Germany. While being assistant and associate professor at the Department of Mineralogy and Petrology of Comenius University, he taught courses on Isotope Geology, Genetic Mineralogy, Fluids in Geological Processes, Heavy and Accessory Minerals. Since his university studies, Hurai is engaged in the study of fluids in all geologic environments, including siderite, magnesite and polymetallic deposits, hydrocarbon prospects, deep mantle and crust, and high-grade metamorphic rocks. Hurai is author or co-author of 43 research articles published in impacted SCI journals. Read More Read Less
