Chastity Aiken is currently pursuing a PhD in Earth and Atmospheric Sciences at Georgia Tech.  Her research with advisor Zhigang Peng focuses on studying deep tectonic tremor, a subtle fault movement in the lower crust, and its interactions with damaging earthquakes.  Her work includes identifying tremor sources that are triggered by seismic waves of a large, distant earthquake along strike-slip faults where tremor has not been previously observed. In 2012, she installed seismometers in Costa Rica that recorded a magnitude 7.6 earthquake.  Her research has covered much of the Western Hemisphere and has been published in international journals such as Nature Geoscience and Geophysical Research Letters. She has won a National Science Foundation Graduate Research Fellowship, as well as an ARCS Foundation Scholarship.  In her spare time, she volunteers for Trees Atlanta, tutors high school students in physics and math, and engages in rock climbing.
