Materials: The Driving Force Behind Tomorrow’s Technology
Materials Science and Engineering (MSE) is the study of how different materials—like metals, plastics, ceramics, and even futuristic materials like graphene—are made, used, and improved. It plays a key role in developing new technologies that shape our world today and in the future!

Think about your smartphone: its screen is made from strong, scratch-resistant glass, its battery relies on advanced materials to store energy, and its tiny circuits use special metals to process information quickly. All of this is possible because of MSE! Engineers in this field discover and design materials that make cars lighter and more fuel-efficient, medical implants safer for patients, and even space exploration possible with heat-resistant materials for rockets.

In this talk, the speaker will present the role of Materials Science and Engineering in today’s fast-growing high-tech industry, and the career perspectives for MSE graduates locally in Hong Kong and opportunities overseas.

Decrypting Earth's 2-Billion-Year Natural Nuclear Algorithm for a Zero-Carbon Future
從奥克洛自然反應堆到創新核能：共築低碳未來
While humanity debates carbon-free energy solutions, the rocks of Gabon in West Africa whisper a 2-billion-year-old truth: nuclear fission is a natural planetary process —fueled by uranium-235 fission, moderated by groundwater rhythms, and entombing radioactive byproducts in mineral lattices for aeons. This primal interplay of neutron bombardment and energy release (E=mc² in action) now underpins China’s nuclear ambitions. With 55 reactors supplying 5% of national electricity, fast-neutron breeder reactors like CFR-600 are expanding uranium utilization by 60x through U-238 conversion. Yet legacy thermal reactors face dual crises: exhausting scarce U-235 and stockpiling millennia-lasting waste, mirroring Oklo’s ancient limits before geologic rains rewrote its fate. 

This talk will decode nuclear science through Earth's primordial Oklo reactors (2-billion-year-old natural fission systems in Gabon), demonstrating atomic principles with real-world physics phenomena: nuclear fission and fusion. Afterwards, we will introduce the state-of-the-art nuclear power technology and pathways towards innovative technologies, analyzing China’s nuclear landscape today. The talk will also conclude with Hong Kong's energy puzzle: how next-gen nuclear synergizes with rooftop solar and offshore wind through high-capacity baseload support, forming weather-resilient clean grids to achieve carbon neutrality.

Depending on the request of the participants, a guided tour can be organised after the talk to visit the CityUHK’s CLP Power Low Carbon Energy Education Centre.

Adolescent mental health – posttraumatic growth
People of all ages can experience mental health issues in their life courses. Adolescence is incredibly challenging in human growth and development. Experiencing unpleasant, significant life events or even traumatic experiences does not necessarily lead to post-traumatic stress disorder.  Research and real-life experiences of my students show that traumatic experiences made them even stronger, and they have a thriving life, which proves post-traumatic growth is real. So, adolescents who are having negative life experiences or mental health issues do not give up on recovery.  You can have a promising future.

Aquatic Animal Virtopsy Lab - Health Assessment of Marine Tetrapods
海洋動物影像解剖研究組－當海豚遇上海龜？
Since 2014, our team has been applied a cutting-edge technique named ''virtopsy'' on local Cetacean Stranding Investigation. This technique was later extended to the research on stranded sea turtle since 2019. This technique enhances better understanding and gives insights into health conditions and life history of the stranded aquatic animals, and their injuries and deaths caused by human interactions. The collected data enables assessment of aquatic animals' health and provides an important reference to the development of a unique centralised database and long-term strategies for conservation of aquatic animals. Such a complete ecosystem indicator may eventually support the conservation and policy decision for all oceans, leading to an "One Ocean-One Health" paradigm.

自2014年起，我們研究組率先應用影像解剖在香港鯨豚擱淺調查的研究，並在2019年延伸至在本港擱淺的海龜。這種創新科技能協助研究人員進一步瞭解海洋動物的健康狀況、其生活史與及由人類活動所造成的損傷和死亡。這些資料有助評估動物健康情況，並可用以建立獨特的資料庫，以協助制定動物保育的長遠策略，以至為整個海洋生態制定保育措施與政策的生態系統指標，從而達至「海洋健康一體化」的目標。

CSI of the Cetaceans: Virtopsy and One Ocean One Health
鯨豚法醫：影像解剖與海洋健康一體化
Cetaceans (whales, dolphins and porpoises) are prime sentinel species because of their long life spans, long-term coastal residences, high trophic level diets, and unique fat storage that can serve as depots for anthropogenic toxins. Cetaceans may be exposed to environmental stressors such as chemical pollutants, harmful algal biotoxins, and emerging pathogens. Since many cetaceans share the coastal environment with humans and consume the same food, they also may serve as effective sentinels for public health concerns.

This talk aims to introduce a cutting-edge technique named ''virtopsy'', which has been applied on Cetacean Stranding Investigation in Hong Kong and adjacent waters since 2014. This technique enhances better understanding and gives insights into health conditions and life history of the stranded carcasses and their injuries and deaths caused by human interaction. The collected data allow measurement of cetacean health trends and provide an important reference to the development of a unique centralised database and long-term strategies for the conservation of local cetaceans. Such a complete ecosystem indicator may eventually not only benefit the cetaceans being studied, but also human health as well by keeping the entire marine environment healthy and supporting the conservation and policy decision for all oceans, leading to an ‘One Ocean−One Health’ paradigm using cetaceans as sentinels of potential emerging hazards.

How to “See” Dark Matter?
如何「見到」暗物質？
Modern cosmology and astrophysics reveal that 85% of the matter in the universe is comprised of dark matter, which seemingly interacts with ordinary matter only through gravitational forces. Despite compelling evidence for its existence, the properties of dark matter remain largely unknown. Considering that ordinary matter consists of a variety of particles engaging in complex interactions, it is natural to hypothesise that dark matter is not "alone". It could be part of the "dark sectors", a collection of hidden particles such as dark photons and dark Higgs bosons. These dark sector particles could mediate the feeble interactions between dark matter and ordinary matter, mediate self-interactions within dark matter, or even be dark matter themselves. I will explore theories related to dark matter and dark sectors, as well as the ongoing searches for them through terrestrial experiments and astrophysical observations.

Aquatic Animal Virtopsy Lab - Health Assessment of Marine Tetrapods
海洋動物影像解剖研究組－當海豚遇上海龜？
Since 2014, our team has been applied a cutting-edge technique named ''virtopsy'' on local Cetacean Stranding Investigation. This technique was later extended to the research on stranded sea turtle since 2019. This technique enhances better understanding and gives insights into health conditions and life history of the stranded aquatic animals, and their injuries and deaths caused by human interactions. The collected data enables assessment of aquatic animals' health and provides an important reference to the development of a unique centralised database and long-term strategies for conservation of aquatic animals. Such a complete ecosystem indicator may eventually support the conservation and policy decision for all oceans, leading to an "One Ocean-One Health" paradigm.

How Veterinarians Detect Viruses in Many Animal Species
During COVID 19, the world saw how important it is to detect new diseases early. Veterinarians were part of this effort, sometimes wearing high safety “space suit” gear to investigate viruses in the field and in special labs. This talk explains how vets study emerging diseases using samples from pets, farms, and wildlife. By comparing infections across animals, vets can ask key questions like: “Could this virus spread to humans?”, “Is this a risk for my pet?”, or “Why did tigers get COVID 19?” In urgent situations, vets may need to study viruses directly in animals to understand how dangerous they are and how they spread. Their discoveries also guide government actions, such as outbreak alerts, public safety rules, and plans to protect both animal and human health.

Solving Medical Mysteries in Dogs and cats
Pets can’t speak or describe their symptoms, vets have to solve “medical mysteries” by acting like detectives for animals who can’t talk. In this presentation, we use real cases to show how vets use history‑taking, physical exams, X‑rays, blood tests, and problem‑solving skills to diagnose illnesses. By putting all the clues together, vets can figure out what’s wrong and how to help the pets get better. Each case is a puzzle, and every test is a new piece that helps complete the picture. Veterinary medicine is not only about caring for animals but also about thinking critically, asking smart questions, and using science to solve real‑life mysteries.

The Essential Role of Fundamental Laboratory Studies in Solving Today’s Air Pollution Issues
Air pollution poses serious impacts on climate, human and ecological health. Addressing today’s most pressing and complex air pollution issues will require a three-legged stool approach of laboratory experiments, ambient observations, and modeling studies. Each leg of the stool is only as stable as the fundamental chemistry that underpins it. This talk will discuss how laboratory studies serve as an essential bridge between ambient measurements and air quality models, and provide the fundamental physics and chemistry of the underlying mechanisms of phenomena observed in the field, which is the basis for generating physically meaningful parameterizations for use in air quality models.

Now or Never: A Pivotal Moment for Climate and Sustainability
The Paris Agreement aims to limit warming to 1.5°C, yet Earth has now recorded an entire year above this threshold. A 1.5°C world brings greater risks to vulnerable communities through intensified heatwaves, droughts, wildfires, and extreme rainfall. Hong Kong’s 2025 climate records—including unprecedented heat, rainfall, storm warnings, and tropical cyclones—show these impacts clearly.

Exceeding 1.5°C could trigger major climate tipping points, from disrupted ocean circulation to thawing permafrost and collapsing coral reefs. Coral ecosystems—vital for biodiversity and coastal protection—could decline by up to 90%. Rising seas and methane release from thawing permafrost further amplify long-term risks for global cities.

Time is short. Limiting warming and securing a livable future requires rapid, ambitious action: phasing out coal, decarbonizing buildings, scaling renewables, electrifying transport, halting deforestation, advancing circular economies, protecting ecosystems, and investing in climate science.

This is a pivotal moment, demanding leadership from academia, policymakers, and industry. The next generation of student's innovation and commitment are essential to delivering bold, scalable climate solutions.

Urban Solar Photovoltaic Technologies
The Hong Kong government has set an ambitious goal of reaching carbon neutrality by 2050. A critical strategy in its overall planning is to increase the deployment of renewable solar energy. In this talk, the speaker will discuss how we can rely on technological innovation to tackle this grand challenge; particularly, we have identified a new generation of printable, flexible, transparent, and color-tunable solar cells as the most prominent photovoltaic technology to promote solar energy deployment in Hong Kong. Such a new solar cell technology can be integrated as tinted solar windows, façades, or curtains with buildings to generate significantly more solar electricity in an urban city, which usually has limited lands and rooftops for installing conventional silicon solar panels.

Urbanisation and Climate Change in Asia: Impacts and Adaptation
During the last 20 to 30 years, because of rapid economic growth, extensive areas of agricultural and rural land in many countries in Asia have been transformed into cities. Such changes have substantially modified the exchanges of atmospheric properties between the land surface and the atmosphere. In addition, these cities, many of which have been known as mega-cities, generate additional heat and pollutants that are injected into the atmosphere. Furthermore, many of these cities have been developed over a short period of time, and hence city planning in general has been minimal. All these consequences of urbanization have great impacts on the regional climate, which will also be affected by global climate change. Thus, cities in Asia have suffered, and will likely continue to suffer, significantly in terms of climate hazards.

In this talk, how urbanization and global climate change can modify the regional climate will first be presented using examples from the Pearl River Delta of China (including Hong Kong) and other mega-cities. The possible impacts of such climate hazards will then be discussed. Examples of actions taken by governments to reduce the consequences of such impacts will be presented.
