The Walter Awards recognize top talent among faculty, researchers and staff at the Jackson School of Geosciences. On Thursday, November 12, we recognized our 2025 awardees at reception in the Holland Family student center, along with the very first cohort of our Machine Learning and Data Analytics for Geosciences graduate certificate program.

Walter Award winners received a certificate, trophy and a cash prize. The annual awards are the school’s most prestigious internal awards and were provided for in an endowment created by Joseph C. Walter Jr. in 1977.
