Seaweed Chemistry, Marine Drug Discovery & Development Marine organisms hold the "blue code" for human health. Marine carbohydrates play a pivotal role in materials science, chemistry, medicine, and biology. Based on this background, I am specialized in the discovery, preparation, isolation, purification and structural characterization of bioactive polysaccharides and oligosaccharides derived from marine algae. My research focuses on the immunomodulatory, antiviral and neuroprotective activities of algal carbohydrates, as well as their structure–activity relationships and molecular mechanisms. I am committed to high-value utilization of marine algal resources and innovative carbohydrate drug development in collaboration with industrial partners, contributing to national health strategies and the sustainable blue economy. I am eager to pursue international collaborations through diverse channels to jointly explore the structure, bioactivity, and ecological roles of algal polysaccharides.
