Xi (Charlie) Ren was trained as a developmental biologist during his graduate study focusing on the vascular and hematopoietic systems. Moving from vascular development to vascular engineering, he joined the Laboratory for Organ Engineering and Regeneration at Massachusetts General Hospital and Harvard Medical School as a Postdoctoral Research Fellow in 2012. He became Instructor in Surgery at Harvard Medical School in 2016. During this time, he developed systematic strategies for engineering functional vasculature based on decellularized organ scaffolds. He joined the faculty of the Department of Biomedical Engineering at Carnegie Mellon University in 2017.
