    other international consortia for the improvement of teaching and learning.
    While in the University of Hong Kong (2012-2020) he served as the
    postgraduate Programme Director and clinic Manager of Implant Dentistry,
    which included a 3-year full-time residency programme (MDS) and a 2 year part

    from seminars, clinical supervision, problem-based learning, clinical and
    research mentoring, live surgery sessions, case-based learning, on-line
    modules, sim-lab preclinical training and more. His responsibilities as

    Kong. The MOOC has achieved exceptionally high engagement by all metrics,
    as documented by research [1] published in peer-reviewed journals. In
    addition, the course achieved an extraordinarily high percentage of
    certificate acquisition. The MOOC has as of today enrolled more than 50, 000
    students and received a Honorable Mention in the 2017 Greater China MOOC
    awards among more than 100 contestants in the category of Course Design and
