Philipp Ruprecht conducting field research in a lava field.

Philipp Ruprecht

Associate Professor He/him/his


Philipp Ruprecht is a native German, and received his Bachelor’s degree in Geological Sciences from Georg-August University Göttingen, Germany, in 2001. After a year abroad at UCLA, he finished his Diplom degree in Geological Sciences (MSc equivalent) at Georg-August University in 2004. Philipp received his PhD in Geological Sciences from the University of Washington, Seattle, USA, in 2009. His dissertation explored the time and lengthscale of magma mixing in natural systems and by numerical modeling in general, and in particular focused on the historic eruptions in 1846 and 1932 of Volcán Quizapu in Chile. Following a three year post-doctoral appointment at Lamont-Doherty Earth Observatory (Columbia University), including a Feodor-Lynen Fellowship from the Alexander-von-Humboldt Foundation, he joined the research faculty at Lamont-Doherty Earth Observatory as a Lamont Assistant Research Professor in 2012. Since April 2016, Philipp is an Assistant Professor in the Department of Geological Sciences and Engineering at the University of Nevada, Reno.

Philipp combines fieldwork with petrologic and geochemical studies on volcanic areas to understand how Earth differentiates, what the inner workings of volcanoes are as well as how volatiles condition the atmosphere, generate pathways for ore formation, and provide real-time insights into volcanic hazards and eruption forecasting. While having a focus on the natural systems and their geochemical fingerprints, his research ties in constraints from the physical processes and fluid dynamics. Philipp has worked in volcanic areas in the entire Americas as well as the Western Pacific and the European volcanoes, but most of his focus has been on Andean volcanoes through the years.
