Research
I am a student of Jeff Freymueller. The main focus of my research is studying volcanic
processes using GPS. My current research includes:
1) Studying Okmok Volcano in the eastern Aleutian Islands. Okmok is an actively deforming volcano and thus is an ideal natural laboratory for studying the interaction of liquid magma, volatiles and the elastic rock surrounding the magma.
2) Modeling subduction zone processes along the Alaska Peninsula. I am using GPS
to constrain the amount of coupling along the plate interface in this region.
3) Summerizing and modeling GPS observations from the 2006 eruption of Augustine Volcano, Alaska.
The precursory activity and eruption in 2005/2006 were extremely well instrumented and the dataset provides for an unprecedented oportunity for multi-disciplinary studies.
