Heyu Ni

Scientist, CBS Centre for Innovation; Professor, Departments of LMP, Physiology, and Medicine, UofT. Platform Director for Hematology, Cancer and Immunological Diseases, St. Michael's Hospital

Expertise: platelet biology and immunology, autoimmune thrombocytopenia, fetal and neonatal alloimmune thrombocytopenia, intravital microscopy to evaluate in vivo events following blood product transfusion

Dr. Heyu Ni is a CBS scientist in the Centre for Innovation and Professor in the Departments of LMP, Physiology, and Medicine at the UofT.
