I am a Research Assistant Professor at the Geophysical Institute of the University of Alaska Fairbanks, and member of the Alaska Volcano Observatory. I lead the Modeling Lab, and my research goal is to create data-based and physics-based methods to better understand subsurface processes and to detect precursory signals to violent natural events (e.g., volcanic eruptions and earthquakes). My current projects involve: (1) investigating the low-temperature thermal anomalies appearing on the surface of active volcanic and hydrothermal systems, and understanding how these anomalies are linked to the release of magmatic gases and pre-eruptive processes; (2) integrating machine-learning techniques with analytical/numerical models to better detect volcanic unrest from tremor and degassing signals; and (3) understanding how subduction zones respond to persistent external perturbations (e.g., tidal stresses) and how this response can inform us on variations in the stress conditions of the subsurface. My research benefits from the analysis of a wealth of geophysical/geochemical data from the Aleutian Arc and elsewhere, including thermal infrared emissions detected with space-borne instruments, ground vibrations, SO2 and CO2 gas emissions, deformation, and chemical diffusion in crystals.
If you are also excited with making a leap in our understanding of solid earth processes; in interpreting the surface manifestations of these processes through data, theoretical, numerical, and lab and field experimental analyses; and in designing methods to better anticipate natural hazards, do not hesitate to contact me. I may be taking on new PhD students!
