General Information

Dr Rui Zhang is a Professor at the School of Computing and Information Systems of the University of Melbourne. He is an internationally leading researcher in the area of big data, data mining and machine learning. Professor Zhang has won several awards including the prestigious Future Fellowship by the Australian Research Council in 2012, Chris Wallace Award for Outstanding Research by the Computing Research and Education Association of Australasia (CORE) in 2015, and Google Faculty Research Award in 2017. His inventions have been adopted by major IT companies such as AT&T and Microsoft. He proposed a novel technique for computing primitive statistics efficiently on extremely fast TCP/IP packet streams. He developed a temporal index called version compressed TSB-tree, which has been implemented in Microsoft¨s flagship database product, Microsoft SQL Server. Dr Rui Zhang obtained his Bachelor's degree from Tsinghua University in 2001, PhD from National University of Singapore in 2006, and has then started as a faculty member in The University of Melbourne since 2007. Before joining the University of Melbourne, he has been a visiting research scientist at AT&T labs-research in New Jersey and at Microsoft Research in Redmond, Washington. Recently, he has been a visiting researcher at Microsoft Research Asia in Beijing regularly collaborating on his ARC Future Fellowship project. Dr Zhang's research interests include big data and AI, particularly in areas of recommendation systems, chatbot, knowledge bases, spatial and temporal data analytics, moving object management and data streams.

If you want to be my PhD student:

 

I have a number of PhD positions. Applicants are preferred who have outstanding record which may be evidenced by one or more of the following achievements:

       (i) Top 3% in your department/major from a well-known university, or

       (ii) Top 30% in your department/major from a world or region leading university (e.g., Tsinghua and Peking University if from China), or

       (iii) Awards or prize in major competitions such as Mathematics competition and  ACM-ICPC with near one of the above, or

       (iv) Strong industrial or system software development experience together with near one of the above.

 

Please send me an email with the following items:

       (i) The email briefly explains your most impressive achievements (e.g., one or more of the above mentioned).

       (ii) Attach CV including English test result (IELTS or TOEFL), your GPA and department ranking if possible.

       (iii) Attach detailed undergraduate transcript; if you are a postgraduate student, also attach detailed postgraduate transcript.

 

Please keep your email short so that your most impressive achievements stand out and I won't miss them. Due to the limitation on the number of students I can supervise and the high competition, I may only respond to some of the requests. If you are self-funded, please state it in the title of the email.

 

If you want to be an intern/visiting student in my group:

 

You need to be self-funded and have a strong record like the above described for PhD student. We have very limited space in the school, so intern/visiting student opportunities are very limited.

 

If you want to do a Master Project with me (this is for UoM Course-work Master students only):

 

Please email me:

(i) a CV (includes your education, GPA, research or work experience, etc)

(ii) undergrad transcript, and

(iii) the scores of the subject you have done in UoM.
