John R.

I am a postdoctoral research fellow at the University of Pennsylvania. I recently completed my PhD in the Soft Earth Dynamics Lab at the University of Pennsylvania, where I studied experimental geophysics and geomorphology. Here, I explored the rheology (the behavior of a material as it deforms) of permafrost, and ""soft solids"" like soil and lunar dust. I probed these materials in unique ways by using robotic legs, and extended my lab findings to really cool landscapes in the field, including pe…
