Prof Gui Changfeng, chair professor and head of the Department of Mathematics in the Faculty of Science and Technology at the University of Macau (UM), has been elected as a fellow of the American Association for the Advancement of Science (AAAS). He is the only scholar in Macao to receive this prestigious honour this year. AAAS is an esteemed scientific society. The fellowship, which is a lifetime honour, awarded to Prof Gui is not only a testament to his research achievements but also an international recognition of his outstanding contributions to the global scientific community.

The American Association for the Advancement of Science (AAAS) is a widely-recognised scientific society, with over 100,000 members worldwide. Its publication, Science Magazine, is widely recognised as the premier international scientific journal. Since 1874, the AAAS Council has annually selected outstanding scientists from its worldwide membership based on their academic impact and scientific contributions. The scientists selected are conferred with the title of AAAS Fellow, which is a lifetime honour that recognises their exceptional achievements.

Prof Gui was previously elected as an inaugural fellow of the American Mathematical Society (AMS) and a fellow of the Simons Foundation in recognition of his significant contributions to the study of partial differential equations. He has also received many awards, including the Research Achievement Award of the Pacific Institute for the Mathematical Sciences, the André Aisenstadt Prize in Mathematics from the Centre de Recherches Mathématiques, the Best Paper Award from the IEEE Signal Processing Society, and the Overseas Cooperation Fund of the National Natural Science Foundation of China.

Prof Gui was the Dan Parman Endowed Distinguished Chair in Applied Mathematics at the University of Texas at San Antonio. In 2006, he was selected as a Chang Jiang Scholar Chair Professor by the Ministry of Education of China. His main research interests include non-linear partial differential equations and image analysis and processing. He has solved many of the world’s challenging mathematical problems. In addition, Prof Gui has published nearly a hundred papers in leading international journals, including Annals of Mathematics, Inventiones Mathematicae, and Communications on Pure and Applied Mathematics.

澳門大學科技學院數學系主任及講座教授桂長峰當選美國科學促進會（American Association for the Advancement of Science, AAAS）會士，是今屆澳門地區唯一獲此殊榮的學者。桂長峰獲全球權威科學學術組織頒授終身榮譽，不僅是對他於科學研究成就的讚譽，也是對其在科學界卓越貢獻的認可。

美國科學促進會是全球廣受認可的科學學術組織，有十多萬名會員遍佈世界各地。該會出版的《科學》雜誌（Science Magazine），被公認為最佳國際科學期刊。自1874年起，美國科學促進會委員會每年都根據學術影響及科學貢獻從全球眾多會員中選出優秀科學家，並授予美國科學促進會會士這項終身榮譽，以表彰他們的非凡成就。

此外，桂長峰因其在偏微分方程研究的傑出貢獻，過去曾當選美國數學學會首屆會士（AMS Fellow）、西蒙斯基金會會士（Simons Foundation Fellow），也曾獲加拿大太平洋數學研究所研究成果獎、加拿大蒙特利爾數學研究中心Aisensdadt獎、IEEE信號處理協會最佳論文獎、中國國家自然科學基金海外合作基金（海外傑青）等。

桂長峰曾任美國德州大學聖安東尼奧分校丹．帕爾曼應用數學冠名講座教授；2006年入選國家教育部長江學者講座教授。他的主要研究領域為非綫性偏微分方程、圖像分析和處理，解決了眾多世界數學難題。他曾在國際頂級期刊如《Annals of Mathematics》、《Inventiones Mathematicae》、《Communications on Pure and Applied Mathematics》等發表近百篇論文。
