Short Bio

Ágata Dias holds a PhD in Geology, specializing in Mineralogy, Crystallography, and Metallogeny, as well as an MSc in Dynamic Geology. Her scientific interests encompass mineralogy, petrology, geochemistry, and marine geology, with a specific focus on deep-sea hydrothermal systems and ore deposits. Since 1996, she has actively participated in research projects related to deep-sea exploration and the study of mineralogy, geochemistry, and ore-forming minerals. Upon joining the ISE, she has also engaged in environmental projects.

In addition to her research activities, Ágata Dias has collaborated with various universities and research institutions worldwide. These include IFREMER in Brest, France; ETH in Zurich, Switzerland; NOC in Southampton, UK; the University of Bergen in Norway; FCUL in Lisbon, Portugal; GIGCAS and the State Oceanic Administration (SOA) in China, specifically the SIO (South China Sea Institute of Oceanology) and SIO (State Key Laboratory of Marine Geology). She has also participated in several scientific cruises. With over 20 years of academic experience, Ágata Dias worked as an assistant and auxiliary professor at ULHT and as an invited auxiliary professor at FCUL, both in Portugal, until she joined ISE-USJ in 2012.
