Danny Broberg is a policy and market development leader focused on scaling carbon removal, currently heading Policy for Stripe Climate & Frontier after advising the U.S. Department of Energy on deployment strategy. With 11 years spanning academic research, legislative fellowships, and policy roles at the Bipartisan Policy Center and the Senate, he bridges first-principles materials science with practical climate policy. He holds a PhD in Materials Science from UC Berkeley and deep technical chops—contributing to major open-source materials projects like pymatgen and atomate where he implemented defect-analysis and charge-correction algorithms. That blend of hands-on computational materials expertise and policy experience gives him uncommon credibility in designing market mechanisms that reflect physical realities of carbon removal. Based in Washington, D.C., he’s comfortable translating atomic-scale insights into federal policy and commercial procurement strategies.

Python Materials Genomics (pymatgen) is a robust materials analysis code that defines classes for structures and molecules with support for many electronic structure codes. It powers the Materials Project.
Role in this project:
Back-end Developer
Contributions:294 commits, 11 PRs, 4 comments in 1 year 5 months
Contributions summary:Danny made significant contributions to the `pymatgen` library, focusing on the development of defect analysis functionalities. Their commits implemented new classes and methods for handling various defect types like vacancies, substitutions, and interstitials. The user also introduced charge correction mechanisms, including the Freysoldt and Kumagai corrections, and expanded the thermodynamics module to handle defect concentrations. The user demonstrated expertise in Python, object-oriented programming, and materials science concepts.
atomate is a powerful software for computational materials science and contains pre-built workflows.
Role in this project:
Back-end Developer
Contributions:24 commits, 2 PRs, 5 comments in 1 year 5 months
Contributions summary:Danny's commits primarily focus on modifying and extending the `atomate` software, which appears to be used for computational materials science. The commits reveal code changes related to the `vasp` module, specifically the `DFPTFW` class within the `fireworks` structure. These changes involve implementing and correcting parameters like `force_gamma` and updating the charge handling within the defect workflow functionalities. The user also merged remote branches, which indicates involvement in integrating updates and maintaining the codebase.
