Carla Pinzón is the founder and CEO of Expand Power, a grid modernization venture building novel compact transformers. She was previously a lead power electronics engineer at Sonos and a Ph.D. candidate at Stanford focused on wide-bandgap semiconductors and high-frequency power electronics. She has held previous electrical engineering roles at Open Water Power, Fitbit, Astranis, and more. She received her M.Eng. and B.Sc. in electrical engineering from MIT.

Expand Power uses high-frequency power electronics to create PowerGuard, an ultra-compact, smart transformer with increased controllability and safety monitoring. PowerGuard can be manufactured domestically with shortened lead times, providing solutions to the transformer shortage that plagues utilities while enabling new distribution loads in previously prohibitive locations.
