Tyler McGrew Meng, Ph.D.
My career in science commenced at the Colorado School of Mines, where I received my Bachelor's in Geophysics with the class of 2015. I completed my graduate research in the Lunar and Planetary Laboratory at the University of Arizona in Tucson, where I studied the surface processes of rock glaciers on Earth and Mars. Now, I am a postdoc in the Department of Earth, Environmental, and Planetary Sciences at Washington University in St. Louis, where I work in the Radar Lab. Our reaserch objective is to characterize the uncertainty of remote sensing measurements on changing cryospheric terrains; my specific focus centers on mountainous regions where rock glaciers contribute to the alpine permafrost environment amidst steep slopes and rough surfaces. My work is driven by a broader interest in using geophysical monitoring methods to investigate the role of melting ice on hydrological systems, climate feedbacks, and impacts on global communities.
