It was a great honor to be the 2021–2022 Henry Darcy Distinguished Lecturer. I am truly grateful to the nominators, the selection committee, the NGWA staff, and Indiana University, who relieved me of my teaching duties for two semesters. I offered three talks, entitled:
- How Are Geochemical Reactions in Aquifers Connected to Climate Change Mitigation?
- Hydrogeochemistry: Recent Advances and Opportunities & Challenges Ahead
- Watershed-Scale Hydrological Models as a Community CyberPlatform for Research, Teaching, and Service to Society
