Professor Han has been engaged in research in the field of bioactive components and quality control of traditional Chinese medicine (TCM) for 30 years. His current research interests focus on the chemical analysis, quality control, and biological activity of herb polysaccharides. His research team newly found the third bioavailability approach for orally dosed polysaccharides, via which polysaccharides can enter intestinal lymphatic route though M cell transport, thereafter directly contact various cells and organs. He has published over 200 SCI papers (with 40 as the first author), accumulating more than 9,000 citations, and a Google Scholar H-index of 59. He holds 29 patents, with 18 licensed, and has been ranked among the top 2% of scientists globally since 2020.
