Prof. Cheng Hon Ki Christopher (鄭漢其) has served as a faculty member at The Chinese University of Hong Kong over 30 years.  Throughout his academic career, Prof. Cheng has published over 200 peer-reviewed research papers and review articles in various international journals on areas of endocrinology, reproduction, chemical analyses, natural product research and drug development.  He is regularly invited to review manuscripts submitted to various international journals.  He is engaged in the editorial activities of international journals.  He has also published many articles and book chapters on the assessment and development of TCM as therapeutic agents or functional foods.  Together with his collaborators on natural product research in Mainland China, Prof. Cheng was awarded a Second Class State Natural Science Award of China in the year 2009.  Prof. Cheng has successfully obtained numerous grants from various organizations to support his research, notably from the RGC, ITF and NSFC.  He has also served as grant reviewers in Hong Kong and overseas, and as a visiting professor of a number of universities. Having supervised over 54 graduate students pursuing their Ph.D./M.Phil. degrees in his laboratory, Prof. Cheng regularly serves in thesis committees of graduate students in CUHK as well as in other universities.  Prof. Cheng’s commitment to research excellence is not only limited to his own laboratory.  As the Managing Director of the Hong Kong Institute of Biotechnology, he is committed to the development of biotechnology and the Chinese medicine industry in Hong Kong. In addition, Prof. Cheng is also the Director of the CUHK Shenzhen Research Institute dedicated towards developing the activities of the university in Mainland China on areas of research, education and entrepreneurship.
