Notes for PhD Applicants

  • You are mostly welcomed to apply Hong Kong PhD Fellowship Scheme.  If you are nominated and in the CityU’s short list of this scheme, you are guaranteed your PhD admission even you fail to obtain this fellowship finally. 
  • If you are already in the PhD programm at some elite mainland Universities (复旦,上交大,国科大等), you are mostly welcomed to apply the joint PhD programme(联合博士学位). In this programme, you can obtain the CityU’s PhD degree simultaneously within the same normal year of study and there is no financial cost required to be paid by students. The application deadline is usually in Janurary each year.
  • I am now mainly affilicated with School of Data Science (SDSC), and only recruit PhD students whose  graduation degree will be PhD in Data Science.  If you want to join the PhD program in Department of Mathematics, you may approach some MA  faculty for the possiblity of co-supervision. 
  • I generally do not take PhD applicants without contacting me before the application deadline (1 December each year).  
  • To maintain a high level of admission standard, the School will conduct a rigorous interview with the applicants and evaluate their academic qualifications. Journal publications may be counted as bonus. Cultural diversity will also be considered for HKPFS applicants. 
  • No conditional offer is guaranteed before you receive the official written offer letter. The Qualification exam (written exam) will be held at the end of the first year and the disqualified students have to leave the program.

    • You have to be both ambitious and persistent; it is ok that your academic performancd is not top. 
    • You may be from any departments at CityU, not only Math. Strong interest in applied math and programming  is definitely required.
    • Send me your transcript form and list your points of interest and skill strengths.
    • It is a huge plus that you know iOS/Android APP development, tensorflow, Unity3D, Javascript, etc., If not, you need a good  GPA (>4.0).
