Data, Algorithms, Internet of Things


I lead Machine Learning for Alexa Smart Home at Amazon. This includes a variety of products such as Hunches which help our customers live more comfortably and sustainably while keeping their families safe. Prior to Smart Home I founded and led AlgoSnap, a startup that accelerates design and deployment of machine learning at the edge for the Internet of Things. I also managed the Computer Vision Research Group at Amazon, led the Device Intelligence Group at Samsung Research, and was a Senior Scientist on the Personalized Relevancy, Ranking, and Recommendation team at Nokia Research Palo Alto.

My primary interests are at the intersection of sensors, HCI, machine learning, and the Internet of Things. My work has also been motivated by the need to protect user privacy in IoT applications. I have a B.Sc. in Computer Science and Mathematics from the University of Toronto as well as M.S. and Ph.D. degrees in Computer Science & Engineering from the University of Washington, Seattle where I led the RFID Ecosystem project.
