Biography

Qiang Huang is a senior research fellow in the School of Computing, National University of Singapore (NUS), proudly working with Professor Anthony K. H. Tung. He is also a member of the NUS Centre for Research in Privacy Technologies (N-CRiPT) and the Centre for Trusted Internet and Community (CTIC). Qiang received his B.Eng. and Ph.D. from the School of Computer Science and Engineering, Sun Yat-sen University, in 2012 and 2017, respectively, under the supervision of Professor Jianlin Feng. From Nov 2011 to May 2012, he was a research intern at the School of Computer Science, University of Birmingham, advised by Associate Professor Shan He. 

Research Interests

• Algorithms: My research focuses on the development of advanced randomized algorithms, with a particular emphasis on locality-sensitive hashing, for large-scale indexing, searching, mining, and data analytics.

• Data Types: My work predominately concentrates on high-dimensional data, encompassing both dense and sparse vectors. I also delve into time-series data like trajectory and sensor data, as well as heterogeneous data.
