Summary
🤩
Rockstar🎓
Top SchoolJeremy Freeman is the founder and executive director of CarbonPlan and a leader in open science who blends hands-on engineering with strategic philanthropy across computational biology and large‑scale data tooling. He helped grow the Chan Zuckerberg science initiative from its early days, directed funding toward the Human Cell Atlas and open‑source infrastructure, and previously led teams at HHMI that produced popular platforms and communities. As an active open‑source contributor he has improved machine‑learning and PySpark behavior in Apache Spark, built full‑stack features for the single‑cell explorer cellxgene, and enhanced visualization tooling in Altair and Lightning. He pairs a PhD in neuroscience with product instinct to move research code into production systems used by millions, including work on mybinder.org which serves roughly half a million monthly users. Notably, he moves seamlessly between low‑level bug fixes (e.g., NumPy/PySpark correctness) and high‑level program design to scale collaborative science.
