The WUSTL Geomorphology group aims to understand and quantify the processes that create the patterns and landscapes on the surface of the Earth and other planetary bodies.

We explore these links between process, form, and landscape evolution with a suite of methods, including, but not limited to, laboratory experiments, numerical methods, field monitoring, and near-surface geophysics. We work at the interface of geoscience, granular mechanics, and solid mechanics to better characterize the behavior and response of natural systems in the face of the natural variability inherent in Earth’s climate system and geologic materials.

We are committed to advancing accessibility, inclusion, and equity in geoscience through mentorship, outreach, and advocacy.

Lab News

April 2021 – We’re excited to welcome Diala Abboud and Robert Kostynick to the lab as incoming PhD Students in August 2021! 

Diala will work towards unraveling the feedbacks between sediment transport and rock damage in bedrock rivers, by way of a  perpetual damage machine. 

Robert will be focusing on developing a signal-to-noise framework for gravel bed river responses to unsteady forcing and changing climate.


August 2020 – We’re excited to be welcoming Dr. Hossein Hosseiny to our group as a post-doc! Hossein will join us in January from the Villanova Urban Rivers research group.


July 2020 – Our group is seeking a new postdoc to work at the intersection of geomorphology and environmental justice.  See the posting here and don’t hesitate to get in touch!


May 2020 – Proud of AGU’s Earth and Planetary Sciences section for establishing this new award, after Marguerite Williams, the first black woman to obtain a PhD in Geoscience in the US. This award aims to recognize mid-career scientists for research AND community-building efforts.

Claire was part of the committee that proposed the award and is thrilled to see it come to fruition!


May 2020 – Check out Claire’s #shareEGU display on her work on rocky coasts!


Apr. 2020 – Jed Dale will be joining the lab as a PhD student in Fall 2020!

Jed comes to the lab from UT-Austin where he is gaining a Master’s in Geography, and with a Bachelor’s from UPenn. Jed will focus on the intersection of biology and fluvial transport processes.


Apr. 2020 – Excited to announce a new NSF-funded project with José Constantine (Williams College)!

The project, titled “EAGER: Collaborative Research: Invisible Floods on the Mississippi River Floodplain – Unravelling the Causes of Urban Flooding in a Community-Centered Approach to Geomorphology”, is aimed towards constraining mechanisms for flooding in Centreville, IL. The project will be in collaboration with efforts from Equity Legal Services and the St. Louis Equal Housing and Opportunity Council.
