I am a marine geophysicist in the School of Oceanography at the University of Washington with a particular interest in the use of seafloor cabled observatories. For my entire career, I have studied submarine volcanoes and the hydrothermal systems they support and I am now engaged in studies of microearthquakes at both Axial Seamount and the Endeavour Segment. At these sites on the Juan de Fuca Ridge, the Ocean Observatories Initiative (OOI) Regional Cabled Array (RCA) and the Ocean Networks Canada NEPTUNE cable observatory are poised to record volcanic spreading events that are anticipated soon. I am involved in ongoing efforts to develop geodetic techniques with cabled observatories. I am leading an NSF funded mid-scale infrastructure COSZO project that will instrument the OOI RCA for subduction zone studies. I am very interested in SMART cables and the fiber sensing technologies for applications to science and offshore earthquake and tsunami early warning. I am a long term advocate for the use of seafloor seismic networks to track vocalizing baleen whales and a presently involved in effort to use distributed acoustic sensing to this end.
In Winter 2025 I will be teaching an undergrad class on Sounds in the Oceans for the second time and in Spring 2025 I will be teaching a graduate class on Marine Geology and Geophysics Processes.
