I am a Research Professor at the Geophysical Institute of the University of Alaska Fairbanks. My primary research interests are:

-Volcano Infrasound and Seismology

-Infrasound Propagation

-Infrasound Signal Detection and Classification

My research at UAF is focused on using infrasound (low frequency sound) and seismic data to characterize and understand volcanic eruptions and other types of explosions. This work enables a better understanding of volcanic eruptions, as well as contributes to hazard mitigation. Volcano infrasound provides a unique way to monitor volcanoes and understand volcanic processes, particularly in remote and difficult to monitor regions. An important aspect of my research has been to integrate infrasound records with other geophysical techniques (e.g. seismic, satellite, thermal) to better understand eruption processes. Further, volcanic eruptions can be used to study the propagation of infrasound at a variety of source-receiver distances, which ultimately leads to a better characterization of the atmosphere.

I also conduct research in nuclear treaty monitoring, including infrasound signal detection, source characterization, propagation, and sensor and station performance. This work is part of the Wilson Alaska Technical Center (WATC).
