Northrop Hall, Rm. 204. Email: bschmandt@unm.edu

Research and Academic Interests:

Geophysics. Research interests are rooted in observational seismology, with a primary focus on resolving Earth’s seismic properties to gain insight into the evolving structure of tectonic plates and the convective processes that occur beneath the plates.
