Research Interests

Current research interests investigate improved methods of vascularization (blood vessel growth) for tissue engineering and wound healing.   This involves approaches that create human blood vessel networks in the laboratory for transplantation into animal models.   Our group is further implementing this concept of pre-vascularization in a liver tissue engineering model where liver organoids are grown in the Laboratory for implantation into mice with liver disease. We are also examining if human endothelial cells demonstrate improved survival when implanted as multicellular spheroids rather than as single cells.
