Junhao Gan is a lecturer in School of Computing and Information Systems (CIS) at The University of Melbourne (UoM). Before joining the UoM, he was a post-doctoral research fellow in School of Information Technology and Electrical Engineering (ITEE) at The University of Queensland (UQ) from April 2017 to July 2018. He received his PhD degree proudly under the supervision of Prof. Yufei Tao in the same school at UQ in 2017, and obtained his bachelor and master degrees at Sun Yat-Sen University in 2011 and 2013, respectively.

Research Interests

Currently, there is a PhD opening with a full scholarship under Junhao's supervision. Applications can be sent in by email attached with detailed transcript (of the applicant's undergraduate study) and a CV that lists the applicant's awards (since high school) and publications. Applicants are required to meet the University's English language requirements (click here for more details). Applications are no longer accepted as soon as the opening is filled. Applicants with strong background in theoretical algorithms and programming are preferred. The accepted student is expected to research on both database systems and theory. 


In publications marked with **, authors are ordered alphabetically, as is a convention of theory papers. In the other publications, authors are ordered by contribution.
