Eshcar Hillel is a member of the Scalable Search Systems Research team, based in Haifa. Her main research interests span scalable systems and platforms for big data processing, including scalable key-value stores, distributed transactional processing, and concurrent data structures for multi-core architecture. She contributes to open source projects (HBase, DataSketches) and published 20+ papers in academic conferences and journals. Eshcar joined Yahoo Labs in 2011, and initially was part of a data science team working in collaboration with the Yahoo ConnectedTV engineering team. Prior to her graduate studies (2001-2004) she was a software engineer at HP (formerly Tandem) Labs, working on the NonStop SQL database engine. Eshcar received her BSc (summa cum laude) and PhD from the Faculty of Computer Science at Technion, Israel Institute of Technology in 2002 and 2011 respectively. Her PhD is in the field of distributed and parallel computing, and focuses on concurrent data structures and inherent limitations of transactional memory.
