Kam W. Leong

Samuel Y. Sheng Professor of Biomedical Engineering (in Systems Biology)

Kam W. Leong’s research explores how cell–biomaterial interactions can be harnessed for therapeutic applications. For over three decades, his team has advanced biomaterials, drug delivery, and gene therapy through molecular and materials engineering.

A central focus has been the development of multifunctional nanoparticles capable of delivering small molecules, proteins, antigens, and diverse nucleic acids, including siRNA, mRNA, and plasmid DNA. These platforms are applied to drug, gene, and immunotherapy, with particular emphasis on enabling nonviral gene editing in vivo.

Another central theme is the modulation of inflammation. His group proposed cationic biomaterials as nucleic acid scavengers to reduce aberrant innate immune activation, a mechanism implicated in autoimmune and chronic inflammatory diseases. This approach has produced nanomaterials that attenuate inflammation in sepsis, cancer, periodontitis, and metabolic disorders. In regenerative medicine, his work revealed how nanoscale and topographical cues regulate stem cell fate and reprogramming. Building on these findings, his laboratory developed scaffolds with integrated functions, such as controlled release of anti-inflammatory agents or scavenging of damage-associated molecular patterns, to enhance tissue repair. To enable translation, his team also developed flash nanocomplexation, an automated, continuous process that produces nanoparticles with uniform properties and can integrate membrane coatings to guide biodistribution. Together, these efforts advance therapeutic delivery, inflammation modulation, and regenerative repair.

Leong graduated with a B.S. from the University of California, Santa Barbara, followed by a Ph.D. from the University of Pennsylvania, both in Chemical Engineering. His publication record includes around 600 manuscripts and 60 issued patents. Leong's contributions have been recognized by his election to the USA National Academy of Engineering, the National Academy of Inventors, and the National Academy of Medicine. Recent awards include the Society for Biomaterials' Founders Award (2022), the IEEE-EMBS Career Achievement Award (2023), and the IEEE Biomedical Engineering Award (2024). Leong has been serving as the Editor-in-Chief of the journal Biomaterials for the past decade.
