The "Hong Kong Scholars Program" is a program where the Mainland Government effectively recommends top PhD graduates to work in Hong Kong. The annual quota for the program is about 50. Selected candidates from Mainland will contact and exchange ideas with Hong Kong Supervisors to formulate the research plan and submit a proposal to the Society of Hong Kong Scholars. The successful "Hong Kong Scholars" will be hired by Hong Kong Supervisors following established local human resources procedures of the university. The monthly salary for the Hong Kong Scholars has been fixed at HK$25,000. Hong Kong Supervisors are only required to pay half the monthly salary (i.e. HK$ 12,500); the remaining half will be paid (RMB 12,500) directly to the postdoctorates by the Ministry of Human Resources and Social Security of China. For the mode of operation and application procedures of the "Hong Kong Scholars Program", please refer to website: http://hkscholars.org/.

Short-term research assistant/associate positions are available for six to twelve months, with possible extension depending on performance. Interested applicants should send your CV and indicate potential areas of collaboration. For enquiry, please contact Prof. Anthony Chen (anthony.chen@polyu.edu.hk).
