Arie Shoshani Earns Lifetime Achievement Award

Arie award

More than 25 years ago, Arie Shoshani realized that researchers were facing significant challenges in organizing, managing and analyzing their scientific data. He set out to develop computer applications to help them better meet the challenges and created the Scientific Data Management Group in the process. » Read More

The Scientific Data Management (SDM) group develops technologies and tools for efficient data access and storage management of massive scientific datasets. We are currently developing storage resource management tools, data querying technologies, in situ feature extraction algorithms, along with software platforms for exascale data. The group also works closely with application scientists to address their data processing challenges. These tools and application development activities are backed by active research efforts on novel algorithms for emerging hardware platforms.

Group Leader: John Wu
