Prof. Jun Xu graduated with an M.Sc. degree in Chinese Medicinal Science from the University of Macau in 2010. He obtained his Ph.D. degree in Pharmacognosy from Hong Kong Baptist University in 2015. Afterwards, he received postdoctoral training and then served as a Research Assistant Professor at the School of Chinese Medicine of HKBU. He was appointed as an Assistant Professor at HKBU in 2022.

His research has generated over 70 articles in academic journals and is financially supported by several government funding agencies, including the Hong Kong General Research Fund (GRF), the National Natural Science Foundation of China (NSFC), and the Hong Kong Innovation and Technology Fund (ITF). Prof. Xu serves as an Editor or Young Editorial board Member for iMeta, Phytochemical Analysis, Journal of Pharmaceutical Analysis, and Chinese Medicine, and is a peer reviewer for over 20 academic journals.

許軍教授先後取得澳門大學中藥學理學碩士學位和香港浸會大學生藥學博士學位，于2022年獲聘為香港浸會大學助理教授，目前在香港浸會大學中醫藥學院教學科研部擔任博士生導師。

在浸大任職期間， 許軍教授成功獲得多項特區政府及其他學校外部資助，其中包括作為首席研究員參與的6個項目，分別來自優配研究金（GRF）、國家自然科學基金（NSFC）和創新及科技基金（ITF）。在科研產出方面， 他已在同行評審期刊上發表70多篇論文，H指數為29。此外， 許軍教授擔任iMeta、Phytochemical Analysis、Journal of Pharmaceutical Analysis和Chinese Medicine等期刊的編輯或青年編委，並擔任20餘種學術期刊的同行評審員。

Prof. Xu was among the first researchers to reveal the detrimental impact of sulphur fumigation on the quality of Chinese medicines. His subsequent research led to a groundbreaking approach to inspecting sulphur-treated Chinese herbal medicinal products through a new chemical marker. This enabled an advance in the safety assurance of Chinese medicines that ultimately delivers substantial benefits to consumers worldwide. The approach was awarded the Gold Medal at the 4th Asia Exhibition of Innovations and Inventions.

Prof. Xu’s achievements include the pioneering discovery of the synergistic efficacy of multi-component interactions in Chinese medicines. This breakthrough has fuelled his investigation into the intricate structure-property relationship between Chinese medicinal components and gut microbiota. These research outcomes highlight the necessity of considering multi-components, particularly polysaccharides—which have often been overlooked—as crucial chemical markers for the quality control of Chinese medicines. Prof. Xu established a quality control method focusing on polysaccharides, which is being adopted by several domestic and international Chinese medicine enterprises, thus underscoring the practical relevance and wide-reaching influence of his contributions.

許軍教授的主要研究方向是建立完善的中藥質量控制體系，以確保其安全性和有效性。他是首批揭示硫熏對中藥質量影響的研究人員之一，並開創性地開發了一種新的化學標記物來檢測硫熏中藥產品，從而推動了中藥安全性的提升，最終將惠及全球消費者。該成果榮獲第四屆亞洲創新與發明展覽會金獎，並被本港多家電視臺媒體報道。

同時， 許軍教授也建立了以多糖為核心的質量控制方法，開創性地發現了中藥多組分相互作用的協同效應。這一突破性進展推動了他對中藥成分與腸道菌群之間複雜的結構-性質關係的研究。這些研究成果凸顯了將多組分（尤其是常被忽視的多糖）作為中藥質量控制重要化學標記物的必要性。目前，這些研究方法已被國內外多家中藥企業採用。
