Marathon Fusion is taking the critical next step to commercialize a fuel processing component essential for fusion power plants. Compared to conventional technologies, Marathon’s approach enables a dramatic reduction in tritium inventory fuel processing cost while easing engineering requirements on other critical systems. This solution is simple, robust, and highly scalable to meet the challenges of commercial fusion.

Kyle previously worked as an engineer at Airbnb on the machine learning platform, and at Zenysis Technologies working with governments to improve health system performance and prevent infectious disease. Kyle earned a Bachelor of Arts in Asian studies from Carleton College.
