Ryan Porter's research is
focused on using seismology to better understand
tectonically active regions. For my research I
have primarily focused on the North and South
American Cordillera and Africa. I have been
involved with projects studying California, Utah
and northern Arizona, Alaska, Colorado, Wyoming,
Peru, and Argentina. I am particularly interested
in how the angle of subduction impacts regional
deformation. Some of the techniques I work with
are receiver functions, ambient noise tomography,
and surface wave tomography. I am also interested
in combining seismic techniques and in measuring
seismic anisotropy to better understand
deformation at depth.
I grew up in the Seattle
area and attended Whitman College in Walla Walla,
Washington. I was always interested in math and
physics but first became excited about geology while
working as a raft guide in Alaska. I went on to major in
Geology and Physics at Whitman and then earned by
PhD in seismology at the University of Arizona in
Tucson, Arizona. I worked as a postdoc at the
Carnegie Institute for Science before taking my
current job at Northern Arizona University. Outside
of geophysics some of my interests include soccer,
mountain and road biking, running, whitewater
rafting and kayaking, triathlons, traveling, skiing
and occasionally climbing.
