01 / RESEARCH
From molecular programming to carrier engineering and microfluidic formulation, we develop delivery systems across multiple length scales.
We design peptide and lipopeptide building blocks, control their programmed assembly, and develop the resulting structures as delivery carriers for drugs, nucleic acids and bioactive molecules.
We develop lipid- and peptide-enabled delivery systems for mRNA, siRNA and small-molecule therapeutics, with emphasis on carrier architecture, targeting and biological performance.
We use microfluidic flow, interfacial effects and oscillatory shear to reprogram delivery-carrier architecture, control spatial organization and hierarchical loading, and enable reproducible, scalable manufacturing.

PRINCIPAL INVESTIGATOR
Professor
Drug delivery engineer working at the interface of peptide programming, carrier engineering and microfluidic formulation.
Lei Zhang received his bachelor's and PhD degrees from Nanjing Tech University. During his doctoral studies, he spent four years as a jointly trained doctoral researcher at the University of Waterloo, and subsequently conducted postdoctoral research at the University of Waterloo and McMaster University. He has more than ten years of study and professional experience in Canada.
The group pursues interdisciplinary research across bioengineering, pharmaceutics and food science under the theme of “Peptide+”. Research spans peptide and lipopeptide design and assembly, microfluidic delivery systems, mRNA/siRNA and drug delivery, and the delivery of functional-food and bioactive components.
He has published more than 60 SCI-indexed papers, including 38 as corresponding author; a representative study has been accepted by Nature Biomedical Engineering. He has filed 19 international and Chinese invention-patent applications, including 6 granted patents. His academic service includes editorial roles across drug delivery, biomaterials and food biotechnology journals.
Our current students bring together backgrounds in pharmacy, food science and engineering, biology and medicine, and bioengineering.
