Our Students

Fatin Nurizzati BINTI MOHD JAYA

Place of Origin: Brunei
Progress: Graduated in 2020
Supervisor: Professor GCF Chan

Excelling in research and postgraduate studies doesn’t just require a keen sense of focus and academic rigour, it also requires a strong set of persuasion skills and plenty of practice in public speaking.

As champion at the recent Visualise Your Thesis Competition 2019, Fatin Nurizzati, Final Year PhD student from the Department of Paediatrics and Adolescent Medicine, was exceptionally honest about the fact that her first foray into public speaking was not voluntary, “In my very first year as a Masters student, I was asked on the spot by my supervisor to give a short talk at this seminar that I was attending, on my research topic to a crowd of academicians and scientists from different disciplinaries”. Ever since then, Fatin has steadily continued to share her research and partake in academic exchange across disciplines, “Sometimes, in distilling key concepts from you field of study, you have to treat your audience like idiots; the art of public speaking lies in breaking down the most complicated ideas and making sure that even those who had never heard of your field would know what you’re talking about”.

Nicodemus WONG

Place of Origin: Canada
Progress: PhD Year 3
Supervisor: Professor YF Cheung

Nicodemus Wong has been fascinated with stem cells since his teens. A second-year PhD student of HKUMed, he has been engrossed in developing induced pluripotent stem cells into cardiac muscle cells as part of a research to study the disease mechanism of congenital heart diseases.

“Learning how to handle stem cells diligently has been the most challenging. But it is very rewarding when I think about how I can improve the quality of life for kids who suffer from these cardiac birth defects,” he says.
