Biography

Dr. Hartmut Grasemann graduated from University of Essen medical school in Germany in 1992. Following his initial training in paediatrics and a post doctoral training in biochemistry he came to the Brigham and Women’s Hospital in Boston, Harvard Medical School for a research fellowship in respiratory medicine. He returned to Germany in 2000 to complete his paediatric training at the Children’s Hospital in Essen, where he was appointed Assistant Professor in 2002 before joining the Division of Respiratory Medicine at SickKids in 2005.

Research

Dr. Grasemann’s research interest is predominantly focused on airway inflammation in Cystic Fibrosis (CF) and specifically on the role of L-arginine / nitric oxide (NO) metabolism in lung and airways diseases. Work from his research laboratory has also largely contributed to the understanding airway narrowing and hyper responsiveness in asthma. His research program is translational in nature, as he’s working with patients, but also with research tools such as animal models or cultured cells, that allows him to take observations from a patient population to a model and then back to the patient. He’s collaborating with clinical researchers but also other basic scientists inside and outside the University of Toronto.
