Ágata Dias has a PhD in Geology (specialisation 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 research projects related with the deep-sea exploration and with mineralogy, geochemistry and ore-forming minerals. Since she integrated the ISE has been also working 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 and participated in several scientific cruises. She has more than 20 years of academic experience. Until join ISE-USJ, in 2012, was assistant and auxiliar professor at ULHT and invited auxiliar professor at FCUL, both in Portugal.
