About Jehan

I studied engineering in the U.S. and started my career in China, working in manufacturing, where ideas turn into real systems.

Today, I work on deep-tech topics such as nuclear fusion, distributed radar, and complex systems. I strive to write about these ideas in a simple, practical way, and my policy writing has appeared in WIRED.

In this newsletter, I share

• How advanced technologies are actually built

• Lessons from engineering, manufacturing, and innovation

• Ideas shaping the future of energy, defense, and society

I’ve previously co-written at atvbt.com and worked on projects like viaprize.org and wikiciv.org. You can give me anonymous feedback here.
