Dr. Ling's research focuses on biomaterials, lipid nanoparticle-based mRNA delivery, blood–brain barrier targeting, endothelial biology, and therapeutic strategies for neuroinflammation and CNS diseases. His current work aims to develop antibody-targeted nanoparticle platforms for brain endothelial delivery and to explore mRNA- and RNA-based approaches to modulate BBB dysfunction, oxidative stress, and inflammatory signaling.
