Short Bio

Ágata Dias has a PhD in Geology (specialization in Mineralogy, Crystallography and Metallogeny) and a MSc in Dynamic Geology. Her scientific interests are mineralogy, petrology, geochemistry and marine geology (Deep-sea hydrothermal systems and ore deposits ). Since 1996 has been involved in scientific projects related with the deep-sea exploration and with mineralogy, geochemistry and ore-forming minerals. Since she integrated the ISE has been more related in environmental projects.

Along her research activities, she has been collaborating with different universities and research institutions around the world, such as IFREMER, Brest, France; ETH, Zurich, Switzerland; NOC, Southampton, UK; University of Bergen, Norway; FCUL, Lisbon, Portugal; GIGCAS, Guangzhou, SIO and SIO of the State Oceanic Administration (SOA), China.

She has 20 years of academic experience. Until join USJ, in 2011, was assistant and auxiliar professor at ULHT and invited auxiliar professor at FCUL, both in Portugal.

Scientific Interests: Mineralogy, Petrology, Geochemistry, Marine Geology (Deep-sea hydrothermal systems and ore deposits ) and environmental sciences
