holds a Ph.D. in electrical engineering from Stanford University, where her research focused on interferometric synthetic aperture radar theory and techniques. She is the Radar Research Lead of Project Soli at Google Advanced Technology and Projects (ATAP). She leads a technical team developing novel radar sensing techniques and systems for human perception and interaction. Soli radar technology has enabled new modes of touchless interaction in consumer wearables and devices, including Google’s Pixel 4 smartphone, Home Hub, and Nest Thermostat. Prior to Google, Dr. Lien worked as a communications engineer at NASA’s Jet Propulsion Laboratory. Her current research interests include radar signal processing and sensing algorithms; modeling and analysis of the underlying RF physics; and inference on radar data.
