I am an Artificial Intelligence researcher with expertise in foundation models, computational decision-making, and multi-agent systems. My work has been applied to diverse domains, including global-scale geospatial intelligence, autonomous mobility networks, and robotics.
At Google Research, I develop foundation models and applications for geospatial intelligence, human mobility, and the built environment. My contributions have driven interdisciplinary published research and real-world product impact across Google Maps, Ads, and other key platforms. Previously, as Research Lead at a Series A startup, I built intelligent digital platforms that optimized urban transportation and advanced smarter cities.
I hold a Ph.D. in Computer Science from Stanford, where my award-winning research on multi-agent decision-making for large-scale autonomous systems was covered by the BBC, Venture Beat, and IEEE Spectrum. I also earned an MS in Robotics from Carnegie Mellon, focusing on advanced robot planning techniques.
