Research Interests

Miao Qiao joined the School of Computer Science, the University of Auckland, in 2018. Her research focuses on the theory and practices of databases with the past and current research topics on indexing, query optimization, big data management and graph analytics. CV.

• Indexing and query optimization. Her past and ongoing research span over topics including graph distance queries, approximate nearest neighbor search in high dimensional space, range thresholding queries on data streams, multi-way join queries in relational databases, local dense subgraph search.
• Efficient processing and analysis of big data, in particular graph data. Her past and ongoing research have explored the computation of different graph metrics, densest subgraph search, community detection, hypergraph clustering, I/O-efficient algorithm design and streaming algorithms.
• Brain network analysis. This is a long-term and interdisciplinary (with medical and health science) research aiming at understanding and explaining the functions of the human brain, and bettering the predictions of the malfunctioning of the human brain with graph analytical techniques.
