POSITION AVAILABLE

      Postdoctoral Fellow (Immunology)

      Our lab is seeking a postdoctoral fellow to conduct research in immune-related mechanisms underlying neurodegenerative diseases.

      The postdoc should work independently with the research assistant and graduate student lead and conduct the research, report findings, assist with the maintenance of the lab, with the opportunities to apply eligible grants. Applicants should possess a PhD in related disciplines with prior experiences in primary cell culture, mice handling, qPCR, ELISA, and immunofluorescence microscopy. Good command of written and spoken English and Chinese is essential. Salary will commensurate with qualifications and experience. Funding for a 2-year appointment can be expected with reappointment available. Applicant should be able to commence duty as soon as possible.

      Interested applicants can contact Dr Allen Cheung via email akcheung@hkbu.edu.hk for further details or enquiries.
