Dr. Boyang Zhang is an Assistant Professor of Chemical Engineering at McMaster University. His lab uses advanced biofabrication techniques to build human micro-tissue models for predictive drug discovery and to construct functional macro-tissues for tissue regeneration in patients. He talks about building microfluidic devices for biological applications and using machine learning to study organoid morphology. He also talks about his team's high-throughput system for vascularizing tissue spheroids and his experience starting a company to commercialize this technology.
