My name is Stan Roozen. I am 28 years old and born and raised in Amsterdam, the Netherlands. Currently, I am doing my Ph.D. at the McGill University in Montreal where I try to make tourmaline a new mineral probe to reconstruct fluid chemistries. I obtained a master degree in earth sciences at the ETH in Zurich with a specialization in geochemistry, mineralogy and mineral resources. My master thesis topic was the hydrothermal-magmatic origin of a porphyry Cu deposit in Argentina. The earth science department of this university was ranked best in the world in 2015 and 2016. During my curriculum, I attended a total of five universities in four different countries: The University of Amsterdam (UvA) and the University of Utrecht (UU) in the Netherlands, the Universidad Nacional Autonoma de Mexico (UNAM) in Mexico, the Swiss Federal Institute of Technology Zürich (ETH) in Switzerland and the McGill University in Canada. I am globally orientated and interested to be able to combine my love for both geologic science and my curiosity to get to know the many parts of the world. I speak, read and write the Dutch, English and Spanish language and I am at a beginner level in French, German and Portuguese. The driving force behind all this was my aim to develop all the facets of my personality so I can readily use my knowledge, my social skills and the languages in the working field.
