Biography

I am a research scientist in the Information Security and Privacy group at CSIRO. I am currently working on federated learning and privacy enhanced analytics for graph databases, and secure and efficient data linkage techniques for large databases.

In my PHD research study I developed scalable techniques for efficient and effective indexing mechanisms in PPRL for multiple parties.
