I am now a Director of Research at AWS and the manager Amazon AI Labs. The Lab is a mix of scientists and engineers who build cutting edge machine learning systems and services for AWS customers. We support SageMaker, Kinesis, QuickSight and other yet-to-be-released services from AWS.
Until mid 2016 I was the Senior Research Director at Yahoo. I was the head of Yahoo’s Independent Research in New York where we focused on scalable machine learning and data mining for Yahoo critical applications. I received my B.Sc in Physics and Computer Science from Tel Aviv university and my Ph.D in Computer Science from Yale University, under the supervision of Steven Zucker. After that, I was a Post-Doctoral fellow at Yale in Program in Applied Mathematics.
My personal research interests include fast dimensionality reduction, clustering, streaming and online algorithms, machine learning, and large scale numerical linear algebra. I am especially fond of randomized algorithms and high dimensional geometry.
