Bio

Founder & VP, Engineering at Ultrasonium Started my R&D career working at national labs by age 15. I have contributed to the ITER fusion reactor and CERN through labs at NHFML and LBNL. I have led teams of fabricators and designers in both research and industry. I am passionate about hard tech and moving groundbreaking research ideas into real products. I lead the Ultrasonium team on the novel and cutting edge technology we implement in our manufacturing process.
