CUHK Research at a Glance: Five Milestones, National Platforms and a Timeline of Breakthroughs

Any account of CUHK's research achievement sooner or later runs into two peaks: one leading to the Nobel Prize in Physics (Charles Kao and optical fibre), the other to the Lasker Award (non-invasive prenatal testing). Beyond these stand the Shannon Award, an AI unicorn, and soybeans bred for saline soil. This article first strings together five world-class breakthroughs on a single map, then sets out the national-level platforms, funding and review performance that underpin them, and closes with a timeline of key breakthroughs. Each breakthrough's scientific depth is covered in its own dedicated article.

# 2. Non-Invasive Prenatal Testing (NIPT): The Fetal Code in Plasma

Background. At the end of the twentieth century, determining whether a fetus carried Down syndrome (trisomy 21) or other chromosomal abnormalities meant amniocentesis or chorionic villus sampling — both requiring a long needle through the mother's abdominal wall and carrying a risk of miscarriage. Reading the fetus's genetic information without a needle was a problem obstetrics had long failed to crack.

Breakthrough. According to the Lasker Foundation^※, the CUHK chemical pathology team discovered cell-free fetal DNA circulating in maternal blood and used it to develop a non-invasive prenatal test for Down syndrome. The foundational finding was published in 1997; as massively parallel sequencing matured, the team was able to count the whole genome of maternal plasma DNA and thereby identify fetal chromosomal aneuploidies with high accuracy. According to the Faculty of Medicine, the test is more than 99% accurate and is now offered in over 60 countries and regions^※.

Impact. NIPT has since gone global. CUHK has cited figures of more than 7 million tests performed annually, covering expectant mothers in over 90 countries and regions^※, sparing vast numbers of women the miscarriage risk of invasive testing. The same "read cell-free DNA in plasma" logic has since been extended to early cancer screening (nasopharyngeal cancer, for example).

Honours. The 2022 Lasker~DeBakey Clinical Medical Research Award^※ (dubbed "America's Nobel"), the 2021 Breakthrough Prize in Life Sciences^※ (the "Oscars of Science"), and — per the Faculty of Medicine^※ — the Royal Medal of the Royal Society, the first Chinese scientist to receive it. For the full scientific story of NIPT, its extension to cancer screening and its commercialisation (Insighta), see Life Sciences and Medicine Breakthroughs.

Note: this volume is the research module; it records, as a matter of fact, the neutral positive facts about the principal inventor of NIPT, Professor Dennis Lo Yuk-ming, as the award-winning scientist. He currently also serves as Vice-Chancellor and President of CUHK; that university-governance context is covered in the overview. "Professor Lo" below refers to Dennis Lo Yuk-ming.

# 3. Fibre-Optic Communications: Charles Kao and the Nobel Road of the "Father of Fibre Optics"

Background. Through the 1960s, long-distance communication relied on copper cables and microwaves — limited in bandwidth and heavy on signal loss. Glass fibre could guide light, but impurities attenuated an optical signal to nothing within a few metres, and the field had broadly concluded that glass was unfit for long-distance communication.

Breakthrough. In 1966, Charles Kuen Kao, working at Britain's Standard Telecommunication Laboratories (STL), argued with a colleague that the high loss of glass fibre was not a physical limit of the material but a consequence of impurities; purify the glass sufficiently and fibre would become a viable long-distance communication medium. According to the Nobel website's official account^※, he is consequently honoured as the "Father of Fibre Optics". His prediction was borne out point by point in the years that followed: the cable networks spanning oceans and continents became the physical skeleton of the modern internet, telephony and data transmission.

Honours and the CUHK connection. Kao received the 2009 Nobel Prize in Physics^※ for "groundbreaking achievements concerning the transmission of light in fibers for optical communication", sharing it with Willard Boyle and George Smith, inventors of the CCD image sensor. According to the obituary issued by CUHK^※, Kao served as the University's third Vice-Chancellor; external obituaries record that during his 1987–1996 tenure^※ he oversaw a period of expansion in which the student body grew from about 7,000 to about 13,000. Kao passed away in September 2018.

# 4. Network Coding: Raymond Yeung and the Birth of a Discipline

Background. In a conventional communication network, information flows like traffic on a highway: each relay node simply "stores and forwards", adding nothing to the content itself. For a long time it was simply assumed that this routing model was optimal.

Breakthrough. In 2000, Raymond W. Yeung published the foundational paper "Network Information Flow"^※ together with R. Ahlswede, Ning Cai and Shuo-Yen Robert Li, advancing a counter-intuitive idea: intermediate nodes need not act as mere "forwarders" — they may perform coding operations on the streams passing through them before sending them on. In multicast networks this attains the theoretical limit set by the max-flow min-cut theorem, which conventional routing generally fails to reach. The result gave birth to network coding as a discipline. According to the IEEE Information Theory Society^※, Yeung is a co-founder of the field; in 2010 he established the Institute of Network Coding at CUHK, funded under the University Grants Committee's Areas of Excellence (AoE) scheme.

Honours. Yeung received the 2022 Claude E. Shannon Award^※ — the highest honour in information theory — "for consistent and profound contributions to the field of information theory"; he has also received the 2016 IEEE Eric E. Sumner Award and the 2021 IEEE Richard W. Hamming Medal. For the theoretical depth of network coding (the Zhang–Yeung inequality, BATS codes), see Information and Engineering Breakthroughs.

# 5. Deep Learning and Face Recognition: Xiaoou Tang, DeepID and SenseTime

Background. Face recognition was long considered a task machines could not match humans at. On the public benchmark LFW (Labeled Faces in the Wild), machines once struggled to reach human-level performance.

Breakthrough. According to CUHK's research office, ORKTS^※, Xiaoou Tang founded the Multimedia Laboratory (MMLab) at CUHK in 2001, making it one of the earliest labs dedicated to deep learning. Per CUHK in Focus^※, in 2014 the team's DeepID family of algorithms achieved 99.15% accuracy in face recognition, surpassing Facebook's DeepFace and marking a milestone in the commercialisation of AI.

Impact and commercialisation. In October 2014, Tang co-founded SenseTime^※ with colleagues to commercialise the technology; per CUHK in Focus, the company listed on the Hong Kong Stock Exchange some seven years later, becoming one of the world's best-known AI unicorns. Tang passed away at the end of 2023. For the academic standing of the Multimedia Laboratory and the incubation of SenseTime, see Information and Engineering Breakthroughs.

# 6. Salt-Tolerant Soybeans: Hon-Ming Lam and the "Seed That Saves Saline Land"

Background. Hon-Ming Lam is a professor in the Faculty of Life Sciences and director of CUHK's Soybean Research Centre. Salinisation and drought are chronic pressures on global agriculture.

Breakthrough. In a paper published in Nature Communications (2014)^※, Lam's team sequenced the whole genome of wild soybean and identified and cloned a new salt-tolerance gene (an ion transporter), markedly improving the efficiency of breeding salt-tolerant soybean. According to a CUHK announcement^※, the team also completed the world's first reference-grade wild soybean genome.

Impact. Bringing that salt-tolerance gene to breeders in mainland China, the team has developed soybean varieties that grow on saline, alkaline and drought-prone land — carrying a laboratory result into the practical concern of national food security. Lam's "Sustainable Agriculture and Food Security" research has also been recognised under the UGC's Areas of Excellence (AoE) scheme. For the full chain from wild soybean genes to the saline soils of Gansu, see Agricultural Biotechnology; for the institutional trajectory of the State Key Laboratory of Agrobiotechnology that Lam now leads — from founding director Samuel Sun's lysine-rich rice to its 2025 reorganisation as a "National Key Laboratory" — see the State Key Laboratory of Agrobiotechnology.

# 7. National Platforms Underpinning the Breakthroughs

These breakthroughs are not isolated feats of individual genius; behind them stands a research infrastructure. According to CUHK's research pages^※, the University hosts State Key Laboratories in translational oncology, agrobiotechnology, digestive diseases, and quantum information technologies and materials; per a CUHK announcement^※, the State Key Laboratory of Quantum Information Technologies and Materials received its plaque in August 2025. CUHK also leads or takes part in six InnoHK centres. For the full list and structure of the State Key Laboratories and InnoHK centres, see State Key Laboratories.

# 8. Areas of Excellence (AoE) and Funding

According to a CUHK announcement^※, in the 2025/26 round of the Areas of Excellence (AoE) scheme and the Theme-based Research Scheme (TRS), four CUHK-led projects received a total of more than HK$220 million; of the three AoE projects in that round, two are led by CUHK. For the funding breakdown, knowledge-transfer mechanisms and spin-off companies, see Research Output and Start-ups.

# 9. The Wider Academic Pantheon: A Nobel Economics Laureate as Distinguished Professor-at-Large, and Members of the Two National Academies and Academia Europaea

The short answer: CUHK's world-class academic standing is not only a matter of breakthroughs produced in-house — it also includes the distinguished scholars the University has attracted and nurtured. A Nobel laureate in economics taught here for sixteen years, and in recent years CUHK scientists have been elected to the academies of sciences on both sides of the Taiwan Strait as well as to the Academia Europaea.

A Nobel laureate as Distinguished Professor-at-Large. According to the obituary published by the CUHK Business School^※, the British economist Sir James A. Mirrlees received the 1996 Nobel Memorial Prize in Economic Sciences for his foundational contributions to the economic theory of incentives under asymmetric information. He joined CUHK in 2002 as Distinguished Professor-at-Large, teaching in the Departments of Economics and Finance and serving as Founding Master of Morningside College, until his death in August 2018 — sixteen years at the University in all. Mirrlees's case differs from the fibre-optic and NIPT stories, where breakthroughs were born at CUHK: he arrived already a Nobel laureate, lending his prestige and international network to the University's economics programme and to Morningside College. He constitutes a third, easily overlooked Nobel connection in CUHK's research story (the other two being fibre optics and NIPT in "Five World-Class Breakthroughs" above).

Members of the national academies and Academia Europaea. According to 21st Century Business Herald^※, NIPT inventor Professor Dennis Lo was elected a member of the Chinese Academy of Sciences (Division of Life Sciences and Medicine) in November 2023; per a story republished via Tencent News^※, he was elected a member of the Academia Europaea in July 2025. The Dean of Medicine, Professor Philip Chiu-wai Chiu, was likewise elected to the Academia Europaea in 2023 (see Medical and Multiscale Robotics). Samuel Sun, founding director of the State Key Laboratory of Agrobiotechnology, is a member of the Chinese Academy of Engineering (Division of Agriculture), as detailed in the State Key Laboratory of Agrobiotechnology. Taken together with the Nobel, Lasker and Shannon awards above, these titles map the network of recognition CUHK scholars hold within the international academic community.

# 10. Global Citation Standing: Highly Cited Researchers and the Nature Index

Highly Cited Researchers. According to a CUHK announcement^※, 17 CUHK scholars made Clarivate's 2025 list of Highly Cited Researchers — six in clinical medicine, six in cross-field categories, four in engineering and one in mathematics, including Francis Chan, members of Dennis Lo's collaborative team, and clinical medicine chairs such as Tony Mok. Per Clarivate's official release^※, the list names more than 6,800 researchers worldwide from over 60 countries and regions and more than 1,300 institutions, selected on the basis of paper citations ranking in the top 1% of their field over the past decade.

Nature Index output. According to the Nature Index's official page^※, in the February 2025 to January 2026 window CUHK recorded a Count of 823 and an adjusted Share of 167.76 in high-quality natural-science journals — an internationally standard measure of high-quality output rather than raw citation counts. Read alongside the RAE 2020 performance and AoE funding above, this sketches the scale and quality of CUHK's research output.

# 11. Research Assessment Exercise (RAE 2020) Performance

According to the UGC's announcement^※, about 70% of all research assessed in RAE 2020 across Hong Kong was rated "international excellence" or above (25% world leading, 45% international excellence). Per CUHK News^※, CUHK achieved the highest proportions of "3- and 4-star" ratings in several units, including engineering (94%), electrical and electronic engineering (87%), law (83%) and education (68%).

# 12. Timeline of Key Breakthroughs

A common thread runs through several of these breakthroughs: real breakthroughs usually begin by overturning received wisdom — fibre optics overturned "glass cannot carry light over distance", network coding overturned "nodes can only forward", NIPT overturned "fetal DNA can only be found in cells", and salt-tolerant soybeans overturned "the answer must lie in cultivated varieties".
