Geomorphology and Environmental Justice
I am the son of an immigrant and the first person in my family to go to college. I had a general interest in the natural environment, but it was not until I had the opportunity to do research as an undergraduate (REU Internship) that I fell head over heels for science. I was blown away by the discovery that our planet changes in significant and observable ways each and every day, and I was eager to learn why.
I have since devoted most of my scholarship to fluvial geomorphology, where I try to answer questions that might unlock the mysteries of how rivers reshape the landscape. Tropical rivers have been a special focus, but I have also been fascinated by our attempts to tame the Mississippi River, North America’s largest and arguably most important river.
My curiosity with the Mississippi led me to Walter Johnson’s River of Dark Dreams, which changed my perspective of river management. In the lower Mississippi, river processes have been curtailed for the benefit of an agricultural economy that depends on the subjugation of people. Once this connection was made, I became committed to scholarship and activism in environmental justice, which has led to impactful collaborations with colleagues in Africana Studies, Environmental Studies, and Chemistry. Our current work involves partnerships with communities in Illinois and Florida facing sustained flooding, contamination, and injustice.
My experience of research as an undergraduate changed the course of my life. As a result, I’m excited to involve students in my work and to help them design projects that reflect their own curiosities. If you’re at all interested in geomorphology and environmental justice, please get in touch.
