Research Interests

My research focuses on bringing artificial intelligence to the physical world to create smarter, healthier, and safer environments. I develop resource-efficient systems and methods that allow us to embed intelligent perception and reasoning into common infrastructure and everyday objects found all around us and realize useful applications that improve our overall quality of life.


My work is at the intersection between systems, embedded AI, and data, spanning several domains including mobile and embedded systems, cyber-physical systems, IoT, wearables, edge computing, smart cities, machine learning, robotics, and digital health.
