I'm the founder and CEO of Pinecone, the first vector database for machine learning.
Until April 2019, I was a Director of Research at AWS and Head of Amazon AI Labs. The Lab built cutting-edge machine learning algorithms, systems, and services for AWS customers. We build parts of SageMaker, Kinesis, QuickSight, Amazon ElasticSearch, Glue, Rekognition, DeepRacer, Personalize, Forecast, and other yet-to-be-released services from AWS.
Before AWS, I was a Senior Research Director at Yahoo and Head of Yahoo's Research Lab in New York. We worked on building horizontal machine learning platforms and improving applications such as online advertising, search, security, media recommendation, email abuse prevention, and many more.
I received my B.Sc in Physics and Computer Science from Tel Aviv University and my Ph.D. in Computer Science from Yale University. After that, I was a Postdoctoral fellow at Yale in the Program in Applied Mathematics.
My research focuses on mathematical foundations and algorithms for challenges arising in dealing with large amounts of data. Topics include fast dimensionality reduction, clustering, streaming algorithms, machine learning, large scale numerical linear algebra, and high dimensional geometry.
