CAREER SUMMARY
Val Troll graduated from St Andrews University, Scotland in 1998 and received his PhD from the GEOMAR Research Centre, University of Kiel, Germany, in 2001. Troll then lectured in volcanolology and petrology at Trinity College Dublin (2001-2008), during which time he habilitated at the Blaise Pascal University Clermont-Ferrand, France, in 2006. In 2008, he took up the Chair of Petrology at Uppsala University, Sweden, which he currently holds.

Carracedo & Troll (eds.):
Teide Volcano
Book Series: Active Volcanoes of the World
279 pages, Springer, 2013.
Teide Volcano has many different meanings ... a 'hell of a job', a navigation point on cloudy days, a challenge beyond imagination, a breakthrough in our understanding of oceanic volcanism that has shaped our way of thinking about volcanoes, and lastly, Teide provides us with a reference point from where to start exploring other oceanic volcanoes in the Canaries and beyond. Here we have compiled the different aspects and the current understanding of this natural wonder.

KiTa-PROJEKT
GEO-SCHULE
Pre-school "Haus für Kinder St. Sebastian" in Dettelbach, Germany, is running the project "Floating Rock" under supervision of Manuela Welter since 2019.
The kids use Youtube, get their questions answered by email and received soundfiles for their audio pen. Some of the content is known by heart by now.
In 2024 our project received the prestigious DIETER BAACKE AWARD for inspiring young children to explore volcanology through STEM learning and creative media education.
In 2023 the pre-school received the TOMMI Promotional Award Pre-School from Prof. Dr. Stefan Aufenanger and the Auerbach Foundation.
