What happens when you put a room full of open-source geospatial experts together, and then give them time to discuss, share, and present? At AGU25 in New Orleans, 21000+ researchers and practitioners from 100+ countries came together under the theme “Where Science Connects Us” to share work that connects data to decisions across Earth science and environmental challenges. We explored innovative approaches to make geospatial research more reproducible, more scalable, and more open.

We at the Berkeley Institute for Data Science celebrate Stacey Dorton upon her retirement from BIDS and UC Berkeley. After graduating from UC Berkeley in women’s studies, she returned to campus in 2015 as our first Administrative Manager while the Institute was just getting started. It is not an exaggeration to say that BIDS would not have developed into a leading data science institute without her! Upon learning of Dorton’s retirement, her colleagues and friends - both current and former UC Berkeley...

Postdoctoral Research Associate at Princeton University, Peter Fackeldey, introduced the solution that finally brings effective and fast calculations to the irregular world of high-energy physics: Awkward Array. Presenting his work "Awkward Array: manipulating nested, variable-sized data with NumPy-like idioms" at BIDS on June 6, 2025, Fackeldey brought...

The energy of the community—educators, researchers, maintainers, enterprise teams, and so many others—was contagious. Every conversation felt like a reminder of why this ecosystem matters and how lucky we are to be part of it.

For those of us working on Berkeley DataHub, the conference was more than a series of talks. It was an...
