Mason Stahl, James M. Kenney Associate Professor Of Environmental Engineering, chaired a conference session on "Applying Machine Learning and Big Data to Understand Complex Hydrogeologic Systems" at the International Association of Hydrogeologists annual meeting In Davos, Switzerland. He also presented a talk entitled "Seasonal groundwater level dynamics in unconfined aquifers across the United States." This talk is based on research from an article with the same title published this summer in the journal Groundwater. The article was co-authored by Mason Stahl and Union alum Tyler Mar '21.

Donald Rodbell, professor of geosciences, recently co-authored a paper in the journal Science that reports that glaciers in the tropical Andes Mountains have shrunk to their smallest size in the last ~12,000 years. The article, "Recent tropical Andean glacier retreat is unprecedented in the Holocene," reports that the concentration of cosmogenic nuclides in recently exposed bedrock at the margin of glaciers in Bolivia, Peru, and Colombia indicates that these sites had been ice covered for at least the past 12,000 years.

Lewis Davis, Thomas Armstrong Professor of Economics, and Astghik Mavisakalyan, professor of economics at Curtin University, published a paper in the Journal of Comparative Economics.
