Hometown: Las Cruces, NM

Affiliation: Environmental Science & Engineering, University of Texas at El Paso / Beaufort Lagoon Ecosystems Long Term Ecological Research (LTER)

Research focus: Permafrost coastal erosion – understanding patterns, drivers, and biogeochemical impacts

Geographic focus: Elson Lagoon (near Point Barrow), Utqiaġvik, Alaska

Current challenge: To better understand the spatiotemporal patterns and drivers of erosion in Beaufort Lagoons, across the North Slope of Alaska. Within the Elson Lagoon, I study the distribution of soil organic carbon in coastal permafrost, its fate into nearshore ecosystems, and to the atmosphere in the form of CO2 and CH4.

New Pan-Arctic Synthesis Paper Published in Nature Reviews

More than 10 PerCS-Net members collaborated on a recent review paper that was published in the journal Nature Reviews Earth & Environment in January 2022 highlighting the drivers, dynamics and impacts of changing Arctic coasts. The article is one of a collection of papers on Permafrost in a warming world published in January that examine the physical, biogeochemical, and ecosystem changes related to permafrost thaw and the associated impacts.
