Benjamin T. Cardenas


My name is Ben, and I am currently a postdoc at Caltech. As a member of the Lamb Surface Processes Group, I am working on questions in modern and ancient fluvial and aeolian sedimentology on Earth and Mars.

Above all, I value exploring these research questions in collaborative settings. Please explore this website, and feel free to get in touch or connect with me online.

Autogenic scour of the Page Sandstone

Autogenic scour of the Page Sandstone


The driving goal of my science is to better connect sedimentary dynamics with the rock record. To this end, I perform research examining ancient strata exposed in the field, active sedimentary systems, the surface of Mars with remote sensing data, and Earth’s subsurface with 3D seismic volumes. I value quantitative approaches, collaboration with diverse expertise, and getting my hands dirty and making measurements.

Please get in touch if you would like a copy of any paper listed here.
