Current Students

Nathan Andersen

[Photo of Nathan Andersen]Nathan Andersen is a PhD candidate in the Department of Geoscience and a Research Assistant in the WiscAr Lab. He earned a BA in Earth and Environmental Science from Wesleyan University and joined the WiscAr Lab in 2011. Nathan’s dissertation research focuses on understanding the assembly, storage, and eventual destabilization and eruption of large silicic magma systems. He integrates several geochronometers including 40Ar/39Ar, 230Th-238U disequilibrium, and trace element diffusion timescales to interrogate the timing, duration, and rates of magmatic processes.

Allen Schaen

His M.S. in Geoscience from the University of Wisconsin-Madison focused on the Eocene to Pleistocene evolution of the Delarof Islands within the western Aleutians Arc using 40Ar/39Ar geochronology. His dissertation work will include application of high precision U-Pb zircon petrochronology along with 40Ar/39Ar thermochronology to study the evolution of Late Miocene granitic plutons in the southern Andes, Chile. Research interests include high precision geochronology, island arc evolution, pluton emplacement, and the volcanic-plutonic connection.

Paola Martínez

Paola has a Geology degree from Universidad de Chile. She has professional experience in the mining industry, but the most recently worked for three years working with the Geological and Mining Survey of Chile (SERNAGEOMIN) focused on regional geology of northern Chile. Her MS thesis is on the geochronology and geochemical history of Antuco Volcano in southern Chile, which is one of the few volcanoes with an isotopically primitive magma source in the southern volcanic zone.

Chase Kresl

Chase is originally from Eagle River, Wisconsin and is currently in his senior year at UW Madison, pursuing a degree in Geoscience. Areas of particular geologic interest include geochemisty, geophysics, hydrogeology, and geochronology.

Salsabila Nazari

She is from Malaysia and is attending the University of Wisconsin on a Petronas Scholarship. She is active in the Taekwondo association, and also doing a directed studies on Linear Mica Continuity (LMC) with an graduate student in Structural Geology. Salsabila’s aims to pursue a career in the oil and gas industry.
