He was selected by the program of “Tianjin Thousand Young Talents Plan” on the year of 2017. He published over 30 peer reviewed SCI papers, 3 book chapters and 1 book. He also served as a member of editor board for 2 international journals.

Research Interests

My research mainly is focused on the structural, functional and nutritional relationships of carbohydrate polymers and dietary fibers.

The specific research goals are to a) understand the fermentability of dietary fiber and phenolic compounds in GI tract; b) target bioactive polysaccharides possessing immune-modulatory effects. For a), both in vitro and in vivo fermentation methods will be applied. Various types of phenolic compounds and various structures of dietary fibers (oligosaccharide and polysaccharides) from post-harvest food product will be targeted. The hypotheses are: 1) the variation in structural features of phenolic and dietary fiber could modify colonic microbiota in distinct manners and result in distinct short chain fatty acid profile. 2) Due to the different dietary habit, the original sources of colon microbiota from different parts of the world/different nationality will be different, which will lead to different fermentability for both dietary fiber and phenolic compounds. For b) Previous researches indicated that glucomannan from dendrobium officinal, α-glucan from ganoderma lucidum, β-glucan from cordyceps sinensis, and pectin from American ginseng all demonstrated immune-modulatory activities, while the overall structures are different. The objectives are to find their structural similarity among all the immune-modulatory polysaccharides and to bridge the gap between structure and bioactivities. The hypothesis is that the special group together with the conformation of polysaccharides could trigger the receptor in the immune cell, which contributes to the immune-modulatory effects of these polysaccharides. Both cell culture and the animal trial will be applied to this research.
