Junmin Gu is a member of the Scientific Data Management group. Her interests include data management, resource management, and distributed computing. She has developed several versions of the Storage Resource Management software for accessing and manipulating scientific data across the grid. They have been currently deployed by many sites in OSG and ESG. Currently she is a key member and developer for the project on data transfers that utilize policies for resource sharing. Prior to that, she worked on the projects for federating OLAP and Object Databases. Junmin received her Master degrees in Mathematics and Computer Science from the University of Wisconsin-Madison. Prior to LBNL, she worked for a consulting firm that develops artificial intelligence solutions for government and industries.
