My research interests include studying earthquake characteristics and studying the structure of Earth's crust and mantle using seismic waves created by earthquakes. Much of my published works focus on areas of active deformation and volcanism in eastern and western Africa, as well as the structure of stable cratons in southern Africa.
My current projects include investigation of African tectonics and volcanism, studies of seismicity and structure in Alaska
, imaging subduction near Fiji and Tonga, and characterization of seismicity in the New York. I am also interested in working with students to investigate the shallow structure and geologic history of the central New York area.
Research Field Work
Seismic (ground motion) data is gathered using networks of instruments called seismometers. Seismometers can measure movements of the ground even smaller than a nanometer, and can detect earthquakes from across the world! During field work, my students, collaborators, and I bury these sensitive instrument in many locations across the area we are studying. The seismometers then make continuous records of ground motion for a year or longer.
For my previous projects, I have conducted field work in Uganda, Tanzania, Zambia, South Africa, Antarctica (South Pole Station and McMurdo Station), the Alaskan Peninsula, and the Adirondack Mountains. Other projects require data collection from the bottom of the ocean, so I have also conducted field work aboard the NSF Research Vessel (RV) Oceanus, deploying Ocean Bottom Seismometers.
In summer 2019, I will conduct field work on Kodiak Island and off-shore of the Alaskan Peninsula aboard the NSF RV-Skuliaq. For details on field seasons, see my C.V..
