My current research focuses on understanding the origin and evolution of volcanic activity in distrubuted volcanic fields through integrating volcanology, igneous petrology, geochemistry, and geochronology. My interests also include volcanic hazards, geothermal systems, and the economic geology of mineral resources associated with volcanic fields.

Volcanology, Geochemistry, Igneous Petrology, and Geochronology
Geochemical heterogeneity vs homogeneity of ignimbrites in the Altiplano-Puna Volcanic Complex (APVC) is linked to a high vs low-flux stage of volcanism at the Chaxas Volcanic Complex.

Determining accurate and precise ages for Quaternary volcanic centers is essential for reconstructing volcanic field histories, understanding magmatic processes, and assessing potential hazards or…
