Thomas Berry
Co-founder, ChIef Product Officer
Thomas co-founded OpenStar out of the Robinson Research Institute with the belief that fusion energy could be built faster and cheaper than anyone thought possible. He built the plasma physics team that proved it, and now leads product development and strategic partnerships as OpenStar moves toward commercial fusion.
