Our lab focuses on how the extracellular environment directs stem cell behavior for endogenous and exogenous lung tissue regeneration. We use a multidisciplinary approach using advances in materials science (polymer design and synthesis), manufacturing (e.g. 3D bioprinting), and endogenous and iPSC-derived lung stem cells to construct these new models.
The main areas of interest of the lab are:
-
Design and use of biologic (acellular) and synthetic scaffolds in diverse manufacturing approaches to bioengineer new lung tissue for transplantation.
-
Understand the role of the extracellular matrix in directing lung stem cell behaviour in vivo and ex vivo during regeneration (normal and pathologic)
-
Build and validate new models of human lung tissue and chronic lung disease to reduce animal usage and for use as drug discovery and therapeutic screening platforms
