# I. Why a "Cross-Disciplinary Platform"?

In a traditional university, research capacity is organised by department or faculty — engineering in engineering, design in design, health sciences in health sciences. Yet many of the great contemporary challenges — carbon neutrality, ageing populations, smart cities, deep-space exploration — are inherently cross-disciplinary. Tackling "smart cities," for instance, demands expertise from engineering, design, data science, and the social sciences.

PAIR was created to address exactly this tension: it does not replace departments, but rather layers a platform structured around frontier topics on top of them, drawing researchers from different disciplines into the same institute or centre to tackle shared problems.

According to PolyU's PAIR launch press release^※, PAIR formally launched in 2022 with the ambition of positioning itself as a research platform that would help Hong Kong and the Greater Bay Area develop into an international innovation and technology hub.

Source strength: PAIR's establishment (2022) and its positioning appear in the PolyU launch press release.

# IV. In-Depth Profiles of Five Research Institutes

Beyond the Research Centre for Deep Space Explorations (RCDSE, covered in detail in aerospace-and-space.md), the other institutes under PAIR each have a distinct focus:

# 4.1 Research Institute for Advanced Manufacturing (RIAM)

The Research Institute for Advanced Manufacturing (RIAM) is PolyU's cross-disciplinary hub for manufacturing technology. According to PAIR's official website, RIAM's core research areas include additive manufacturing (3D printing) and integrated forming of composite structures; smart production for Industry 4.0 (robotic automation, digital twins, in-line quality inspection); and ultra-precision manufacturing and micro/nano fabrication processes (with research collaboration ties to the State Key Laboratory of Ultra-precision Machining Technology, see state-key-laboratories.md). RIAM works with industry partners such as the Hong Kong Science Park and the manufacturing committee of the Hong Kong General Chamber of Commerce (HKGCC), aiming to channel PolyU's manufacturing research outcomes into small and medium-sized enterprises.

# 4.2 Research Institute for Artificial Intelligence of Things (RIAIoT)

The Research Institute for Artificial Intelligence of Things (RIAIoT) focuses on the deployment of edge computing and embedded AI systems in urban sensing; low-power sensor networks (LoRaWAN, NB-IoT) and data fusion; and application scenarios for smart buildings, smart transport, and industrial IoT. According to PolyU, RIAIoT's research outcomes have already been deployed in pilot projects across several large property management organisations and industrial estates in Hong Kong.

# 4.3 Research Institute for Quantum Technology (RIQT)

The Research Institute for Quantum Technology (RIQT) represents an emerging research direction for PolyU in recent years. It works on quantum communication and quantum cryptography (QKD, quantum key distribution); quantum sensing and quantum precision measurement; and the fabrication and characterisation of quantum materials. According to PolyU's information, RIQT maintains academic exchanges with quantum research units at other local universities and actively incorporates postgraduate students into its quantum laboratory projects.

# 4.4 Research Centre for Chinese Medicine Innovation (RCMI)

The Research Centre for Chinese Medicine Innovation (RCMI) is the PAIR centre most closely engaged in combining traditional medicine with modern biotechnology. Its research priorities include the isolation, identification, and pharmacological mechanisms of active compounds in Chinese herbal medicine; clinical evidence studies on Chinese medicine treatments for chronic diseases (diabetes, cardiovascular conditions); and collaboration at the clinical data level with the new Hong Kong Chinese Medicine Hospital (which opened in 2024).

# 4.5 Research Institute for Sports Science and Technology (RISports)

The Research Institute for Sports Science and Technology (RISports) concentrates on sports performance science and injury prevention — sports biomechanics and motion-capture analysis, athlete rehabilitation and injury-prevention equipment design, wearable sports sensors, and real-time data analysis platforms. PolyU states that RISports has collaborative agreements with the Hong Kong Sports Institute (HKSI) and several Hong Kong national team programmes, providing scientific and technological support to elite athletes.

# V. How PAIR Connects to National and Greater Bay Area Strategy

PAIR's chosen topics — carbon neutrality, deep-space exploration, smart cities, smart energy — align closely with China's national science and technology strategy and the development of the Greater Bay Area as an innovation and technology hub. PolyU materials state that PAIR aims to contribute to building Hong Kong and the Greater Bay Area into an international innovation and technology hub.

PolyU research projects have also received support through relevant funding schemes — according to PAIR materials, the university's projects have secured funding from schemes such as the RAISe+ programme. This kind of connection makes PAIR not just an internal organisational innovation, but an institutional channel through which PolyU integrates into the regional and national innovation system (for more on the Greater Bay Area strategy, see 09 Internationalisation · Greater Bay Area).

Source strength: The Greater Bay Area innovation hub positioning and RAISe+ funding are noted in PolyU's PAIR materials.

# VI. Frequently Asked Questions

Q1: Does PAIR have a direct postgraduate training function?

Yes. According to PAIR's official website, each research institute and centre offers a number of postgraduate places, predominantly for PhD students. Students pursue their doctoral research in the institute's laboratories, supervised by faculty drawn from different departments — and this is the core of PAIR's cross-disciplinary model: a single PhD student may be co-supervised by faculty from engineering, medicine, architecture, and other disciplines (for details on the Graduate School and PhD fellowships, see graduate-school-and-phd.md).

Q2: How does PAIR compare with similar platforms at other universities, such as HKU's HKU-ZIRI?

PAIR's distinctive feature is its 「全學科覆蓋」 ("full-discipline coverage") — spanning deep-space exploration, quantum technology, AIoT, smart energy, Chinese medicine, and sports science, it cuts across STEM fields and cross-disciplinary boundaries. Its two-tier structure of 「研究院 + 研究中心」 ("research institute + research centre") allows large-scale cross-disciplinary projects (at the institute tier) to coexist alongside more focused thematic research (at the centre tier), avoiding the loss of cohesion that can come with oversized organisations. HKU's ZIRI and various institutes at HKUST each have their own emphases; PAIR's advantage is how it complements PolyU's tradition of applied, technology-oriented work and its accumulated strengths in manufacturing, design, and the health sciences.

# VII. Placing PAIR within PolyU's Research Landscape

The relationship between PAIR and PolyU's other research pillars can be understood as follows:

• State Key Laboratories (ultra-precision machining, climate adaptation for coastal cities): long-term, deep cultivation in specific domains at the national level (see state-key-laboratories.md);
• Spaceflight instrumentation (sampling systems, Mars cameras): individual flagship engineering achievements (see aerospace-and-space.md);
• PAIR: the cross-disciplinary platform that integrates all the above laterally, organised around common problems.

If the State Key Laboratories and aerospace achievements are the "points" of PolyU's research, PAIR is the platform that connects those points into a "surface." It represents the direction in which PolyU's research is evolving: from isolated breakthroughs to a platform-based, cross-disciplinary approach aligned with regional strategy.
