Hang Xiao

Hang Xiao is an Associate Professor in the College of Natural Sciences at the University of Massachusetts Amherst, with a research focus at the intersection of nutritional science, food chemistry, and gut microbiota research. His work primarily investigates the health implications of food bioactives, particularly polysaccharides and other compounds derived from mushrooms, plants, and marine sources, with emphasis on their effects on gut health and inflammatory conditions.

Dr. Xiao's research interests center on the food-gut axis, with particular expertise in how dietary components interact with the gut microbiome to influence health outcomes. His laboratory employs in vitro gastrointestinal models, animal studies, and clinical approaches to investigate how food bioactives modulate gut barrier function, immune responses, and microbial ecology. Much of his recent work focuses on mushroom polysaccharides, citrus flavonoids, and other plant-derived compounds and their effects on inflammatory bowel disease, metabolic health, and gut microbiota composition. His research bridges fundamental food chemistry with translational nutritional science, aiming to develop evidence-based dietary strategies for improving gut health.

Analysis of Dr. Xiao's recent publications reveals a strong thematic focus on gut microbiota interactions with dietary components, particularly examining how food bioactives modulate microbial metabolism and host responses in inflammatory conditions. His work spans from fundamental characterization of food components to applied studies on their health effects, with increasing attention to sustainable food systems and waste valorization. The research employs diverse methodologies including in vitro digestion models, animal studies of colitis, metabolomics, and microbiome analysis.

Dr. Xiao maintains an active research program with numerous collaborations both within UMass Amherst and with international institutions. His laboratory appears to involve multiple graduate students and postdoctoral researchers, as evidenced by the pattern of co-authorship across numerous publications. While specific grant information is not provided in the available text, the volume and diversity of his research outputs suggest substantial external funding support for his work in nutritional science and food chemistry.

Based on publication patterns, Dr. Xiao likely leads a research group focused on food-gut interactions, with laboratory facilities supporting in vitro digestion modeling, microbiome analysis, and food component characterization. His work appears to bridge basic food science with clinical applications, suggesting collaborations with medical researchers and potential translational pathways for dietary interventions targeting gut health.
