Biography
I studied Geology at the University of Freiburg, Germany, and the University of Oregon, USA, and received a diploma degree (M.Sc.) in Geology from the University of Freiburg in 1996 with a thesis on the volcanological and geochemical evolution of Monte Fossa delle Felci (Salina, Aeolian Islands, Italy). In 2001, I obtained a doctorate (Dr. rer. nat.) in Mineralogy from the University of Freiburg with a study on the eruptive history and magmatic evolution of Merapi volcano, Indonesia.
After postdoctoral positions at the University of Freiburg and The Open University, I joined the School of Physical and Geographical Sciences at Keele University in 2005 as a lecturer in Mineralogy and Petrology. I was promoted to Senior Lecturer in 2012.
Research and scholarship
I have a wide range of interests in the fields of igneous petrology and volcanology. At present, these are focused on the following themes:
- Volcanostratigraphy
- Magma genesis and evolution in volcanic arcs and other geodynamic settings
- Magmatic processes and their impact on eruption dynamics
- Rates and timescales of magmatic processes using short-lived isotopes
- Volatile behaviour in volcanic systems and the environmental impact of volcanic eruptions
- Emplacement of pyroclastic density currents
- Volcanic hazards and risks
Current study and field areas include:
- Aeolian Islands (Italy)
- Azores (Portugal)
- Santorini (Greece)
- Sunda arc, Indonesia (Merapi)
I am a member of the Keele Petrology Group, and research centre lead of the Centre of Geography, Geology and the Environment.
