RECENT INVESTIGATION
During my Ph.D. I studied the post-caldera pyroclastic activity of the La Primavera caldera volcanic complex in Mexico. I described and correlated the deposits of 14 subplinian to plinian eruptions with their source volcanoes in the La Primavera volcanic complex, using field descriptions, component analysis, geochemistry, and radiometric datings. I also used the stratigraphic relations between the pyroclastic deposits and lavas, radiometric datings, and geochemical analyses to improve the evolution model of the volcanic complex (Sourisseau et al., 2020).
I am currently studying the Holocene pyroclastic eruptions of La Primavera that came from the Colli dome, volcano located in the western part of the Guadalajara Metropolitan Area in Jalisco, Mexico. I am also using the chemistry of the post-caldera pyroclastic units to understand the processes involved in the generation of the La Primavera magmas.

RESEARCH INTERESTS
Research interests:
- Reconstruction of volcanic histories using the relations between pyroclastic deposits and lavas, component analysis, geochemistry, and radiometric datings.Reconstruction and quantification of the physical properties of pyroclastic eruptions.Description and correlation of tephras from lacustrine, marine, and/or glacial depositional settings (DSDP, ODP, and IODP expeditions, etc.) with their source volcanoes to establish detailed frequency records of volcanic eruptions, improve records of large magnitude volcanic events, and correlate paleoenvironmental records.
