Research of Prof. Yi-Qing Ni’s Team Published on Nature Communications

A recent study by Dr E Deng, CEE Research Fellow, and Prof. Yi-Qing Ni, Chair Professor of CEE, has been published in Nature Communications. The article, titled “Tropical Cyclone Rainfall Extends Inland”, explores the global landward extension of tropical cyclone rainfall and its implications for inland flood risk. The study demonstrates that tropical cyclone rainfall has extended inland globally from 1980 to 2023. Along the continental coasts of the Northern Hemisphere, the landward extent of tropical cyclone heavy rainfall has increased at a rate of 3.8 ± 1.8 km per decade (95% CI). Observations and model simulations suggest that nearshore sea-surface temperature warming is closely linked to this extension. Coastal urbanization may further enhance this trend. As coastal cities continue to extend inland, the landward extension of tropical cyclone heavy rainfall could exacerbate inland population exposure and potential flood risk. Nature Communications is an open access, multidisciplinary journal dedicated to publishing high-quality research in all areas of the biological, health, physical, chemical, Earth, social, mathematical, applied, and engineering sciences. Papers published by the journal aim to represent important advances of significance to specialists within each field. This research is supported by the Research Grants Council Theme-based Research Scheme (Grant No. T22-501/23-R). Review the full article: https://www.nature.com/articles/s41467-026-70647-1

Dr Yong Tao Secures Grant from PROCORE - France/Hong Kong Joint Research Scheme 2025/26

Congratulations to Dr Yong Tao, Research Assistant Professor of CEE, for securing HK$61,200 from the PROCORE - France/ Hong Kong Joint Research Scheme 2025/26 introduced by the Research Grants Council (RGC) and the Consulate General of France (CGF) in Hong Kong. Under the scheme, Dr Tao will collaborate with Prof. Roland J.M. Pellenq, Director of Research at CNRS, French National Centre for Scientific Research, for 2 years. Dr Tao’s research project, titled “Cementitious Optimization Against Seawater Threats (COAST)”, aims to enhance the long-term durability of concrete infrastructure in harsh marine environments. By combining experimental research at PolyU with advanced computational modeling at CNRS, the research team will investigate the fundamental degradation mechanisms of cementitious materials under seawater attack. Ultimately, the project seeks to develop predictive durability models and engineer next-generation, resilient cement formulations, directly contributing to global decarbonization and sustainability goals in the construction sector. The PROCORE scheme is designed to promote high-quality research collaboration between Hong Kong and France. It provides one to two year travel grants to support researchers from both sides in conducting joint studies, exchanging expertise, and distributing new research outcomes. We extend our heartfelt congratulations to Dr Tao and we look forward to seeing the impactful research outcomes generated through this international collaboration. For more details about the funding results of the PROCORE, please visit: https://www.ugc.edu.hk/eng/rgc/funding_opport/fr_hk_jrs/funding_results/frhk2526.html
