Dr. Shelef received a Ph.D from Stanford University in 2014 with an emphasis on geomorphology and tectonics. He was a Post-Doctoral Scholar at Los Alamos National Laboratory in 2014-2015 before joining the department in 2015.
Our group studies the multi-scale interactions between geomorphology, climate, hydrology, and tectonics using a combination of field methods, process-based models, topographic analysis, and geospatial statistics. Research projects typically start with field observations, air photos, and topographic data that inspire hypotheses. We then use numerical and analytical models to quantitatively explore these hypotheses, and apply field-work-based, topographic, and statistical analyses to test model consistency with natural processes and forms. Current research activities focus on linking climate-change with hillslope and riverine processes in Arctic regions, modeling of landscape evolution by various types of erosive processes, and deciphering environmental information from the geometry of channel networks.
