Hai-Quan Mao is a Professor of Materials Science and Engineering at Johns Hopkins University, with a joint appointment in the Biomedical Engineering Department (School of Medicine). He directs the Institute for NanoBioTechnology (INBT) and leads the Translational Tissue Engineering Center. His research focuses on biomaterials, regenerative engineering, and immunoengineering, particularly developing nanomaterials for therapeutic delivery and tissue regeneration. Mao holds 35 U.S. patents, co-founded two biotech companies, and received prestigious awards including National Academy of Inventors Fellow and NSF CAREER Award. Education: BS in Chemistry (1988) and PhD in Polymer Chemistry (1993) from Wuhan University. Postdoctoral training at Johns Hopkins (1995–1998), followed by roles at Johns Hopkins Singapore (1999–2003) before joining the Whiting School faculty. Research emphasizes nanofiber scaffolds for liver/nerve regeneration, DNA/lipid nanoparticle engineering for gene therapy, and artificial lymph node matrices for immunotherapy. His lab translates biomaterials innovations into clinical applications, with NIH-funded projects addressing cancer, malaria, and tissue damage. Awards include over 60 provisional patents, multiple Johns Hopkins translational awards, and Thalheimer Awards for research. He serves as associate editor of Biomaterials and editorial board member of major journals. Lab activities include scalable nanoparticle manufacturing, machine learning for material design, and collaborations with industry/clinical partners. Recent work includes lipid nanoparticle optimization for mRNA vaccines and exosome-based therapies for Crohn’s disease.
