Research Areas
1. Brain and Cognitive Sciences
Cognitive functions are orchestrated by neurons and glial cells in different regions of the brain, and represent one of the major issues in neurodegenerative diseases and brain disorders. Our School collaboratively investigates the molecular events that support cognitive functions, including the formation and retraction of synapses, dendrites and axons. We use zebrafish, Xenopus, rat, and mouse as genetic model organisms to investigate neurodevelopment, neuromuscular junction formation, physiological functions of neurons and glial cells, neuroinflammation, and pathological mechanisms that lead to neurodegeneration and neurocognitive disorders. We also assess the value of deep brain stimulation, neuroprotective effects from exercise and diet, and the potential utility of stem cells in neuroregeneration.

2. Cell Signalling and Cancer Biology
Cell signalling defines the means via which cells sense and respond to internal and external cues, and is fundamental to cell proliferation and survival, cell-cell communication, and cell differentiation and organismal development. For instance, when cells detect changes in nutrient levels within its microenvironment a cascade of signalling events would ensue such that cell and tissue homeostasis can be maintained. One important focus of study within our School is cell signalling and how its alteration can lead to various diseases including cancer. Members of our School are also researching on a wide variety of aspects of biology implicated in the origin and growth of cancer, including cancer stem cell and self-renewal, DNA replication and repair, metabolism, metastasis, cell cycle and immune escape.

4. Stem cell, molecular and developmental genetics
Research in developmental biology provides invaluable insights into the molecular events that underlie the diverse cellular changes as tissues and organs are formed during embryogenesis. However, as tissues and organs are formed from a single totipotent stem cell, namely the fertilized zygote, that undergoes well-defined cell divisions and progressive lineage differentiation to specific cell types in the body, it is tightly linked to stem cell biology. Further, it also links to the study of rare diseases where mutations in specific genes can result in developmental defects. Thus, this research area of the School in stem cell biology, developmental biology and functional genetics work hand in hand to resolve complex questions in understanding disease mechanism, control of stem cell differentiation and cell function, with the opportunity to provide therapeutic interventions through drug discoveries and application of regenerative medicine. Specific areas of focus include musculoskeletal, neurological, metabolic, and ageing defects.

5. Stem Cell, Molecular and Developmental Genetics
A transdisciplinary understanding of biomolecule function at the atomic level provides insights into the molecular biology underlying all of life and medicine. We are now moving from observations of the structure and dynamics of molecular complexes and machines (structural biology), towards perturbing these systems (chemical biology), through to re-engineering biomolecules by both rational design and evolution (synthetic biology). Our School has deep expertise in these areas - integrating structural biology with functional proteomics, nucleic acid evolution with translational technology, and artificial biological circuits with genome engineering. Such approaches are allowing new ways to better understand biology and medicine, and allow translational angles across therapeutics, diagnostics and bioengineering.

Our Students
Victor Gray
Place of Origin: France
Progress: PhD Year 2
Primary supervisor: Dr HGS Ling
"Your supervisor will be the person from whom you may seek the most support, so it’s important to build a strong foundation early on".
As a budding researcher and academic, Victor Gray believes in the importance of developing a good relationship with one’s supervisor, as they often have much wisdom to impart on how to deal with stress and future planning, "They have been through what you are currently going through, so they naturally have lots of advice to give you”.
Coming from the UK with an interest in immunology, he looked forward to fine-tuning his research skills under Dr Ling Guang Sheng; “She is someone who has shown expertise in the field for a number of years back in my home country, so I'm very excited to be a part of this transition of immunology research at HKUMed as our team expands”.
Victor now hopes to study in greater detail how various environmental conditions affect the metabolic properties of immune cells, and identify metabolic pathways which may be targeted in order to boost immune responses; "This is especially relevant in the context of cancer and chronic viral infections, where the metabolic properties of immune cells play a crucial role in the outcome of these conditions”.

Jessie Ho
Place of Origin: Hong Kong
Progress: PhD Year 2
Supervisor: Dr R Jauch
“As someone who is easily stressed and anxious, pursuing my hobbies and passions outside of the lab have been critical in helping me reduce my stress to a manageable level”
Living up to the mantra of ‘work-life balance’, Jessie Ho, a Year 2 PhD student, remained active in a plethora of hobbies before the pandemic, “I am an avid tennis player; I began playing Quidditch with Hongkong Hydras; I practiced and performed with my band and the Lap-Chee Acapella Team at the Residential Colleges; I also made sure that Saturday nights and Sunday mornings were reserved for spending time with my family.”
Though many postgraduate students often find themselves buried in work, Jessie believes in the importance of healthily managing stress, especially when pursuing academia. “There have been times where I have felt overwhelmed, which can translate into technical errors and lead to unusable data, so these hobbies have been critical in helping me reduce my stress to a manageable level.” This is all the more important, given that “high-quality research takes time to plan and execute”, Jessie added.
“I do not believe having research completely consume one’s life...that is why I try to make an effort to relax and enjoy my hobbies, and most importantly spend time with the people I care about.”

Maja Højvang Sørensen
Place of Origin: Denmark
Progress: PhD Year 3
Supervisor: Dr RCC Chang
"The drive here in Hong Kong is so different…everything works at a much faster pace here compared to back home”.
For Maja Højvang, a second year PhD student from Denmark, the initial culture shock of working in Hong Kong left an impactful impression, "It's faster, everything just works so much faster research-wise - you produce so many more results daily, compared to back home…but also the research is quite interesting here".
Luckily, she's taken a liking to the fast-paced culture here as it pushes advancement in her current research. She hopes that her work could take her one step closer into achieving her goal of improving life quality for patients with Parkinson's Disease. "It always motivates me if I can make life a bit better or easier for other people. So, if we could help slow down a degenerative disease and its spread in the brain…that would make me feel better about the value of my work".

Zurn Chaiyaporn Kuwentrai
Place of Origin: Thailand
Progress: PhD Year 3
Supervisor: Professor JD Huang
“…The way I look at my PhD, it's a stepping stone that will build up my resume but also my research experience…”
For Zurn Kuwentrai, a first-year PhD student at the School of Biomedical Sciences from Thailand, his postgraduate studies at HKU marks his first foray into the world of academia which is full of challenges but also many new opportunities. “I have had very little research experience [so] my PhD research is very new to me…essentially I'm learning everything in one go during my first year."
Zurn also values being able to pursue his PhD on his own terms, without the pressures of preconceived expectations, “My goals are slightly different from others; I don’t feel the absolute need to publish, or apply to be a Principle Investigator in the future. I just want to learn as much as I can and the experience here itself is…what my goal is, and I'm already getting it every single day I walk into the lab."
As for what’s next in store for Zurn, he hopes his focus on mRNA therapeutics will allow greater accessibility to treatment options for patients, “Less developed countries find it very difficult to afford protein therapies, so we are currently developing ways to make our mRNA therapies equally good so that one day, it can be in the market as well."

Daisy Tan
Place of Origin: Philippines
Progress: PhD Year 1
Supervisor: Dr R Jauch
“We all find it quite funny hearing each other’s stories from our respective home countries – something like having to buy your own reagents and distilled water like I did for my experiments is unheard of to my lab mates!”
Daisy Tan, an MPhil student from the Philippines, reckons that working in a diverse group of passionate researchers at her lab has been an asset to her research experience here, not only because they get to trade stories and anecdotes, but also because there’s such diversity in their skillsets too.
“We have individual meetings with each other to catch up on our respective projects, so even though we’re working on separate tasks, we can always seek the individual expertise of one another […] part of the culture here is to troubleshoot together, and learn from your fellow lab mate who may have stronger foundations in other areas of academia; take molecular biology for example, that’s something I only learnt from them after coming here”.

Smaranda Badea
Place of Origin: Romania
Progress: PhD Year 4
Supervisor: Professor JD Huang
Romanian-born Smaranda Badea spends the bulk of her time at the Faculty Core Facility, where she taps into the multi-million dollar advanced imaging and cellsorting technologies for her research.
Smara, who will soon be graduating with a PhD degree in Neuroscience, has been investigating the way our body responds to injuries in the nervous system.
“Our nervous system tends to react very strongly when it is damaged by injury. What we can do is try to modify how it responds, using particular pathways to calm it down, so that it will prioritise repair over the typical response that would sustain the damage,” says Smara, who hopes the findings from her research might be applied to treating other conditions such as multiple sclerosis and spinal cord injuries.
