Brief Biography

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.

- lung disease in sickle cell patients

Future Research Interests

Recent work from our group has demonstrated alterations in nitric oxide metabolism with potential detrimental effects on multiple aspects of obstructive airway diseases. These involve increased activity of arginase, an enzyme competing with nitric oxide synthases for the common substrate L-arginine. Furthermore, we found evidence that L-arginine deficiency contributes to both decreased NO formation and airway obstruction in patients with cystic fibrosis. Future research will focus on identifying the underlying mechanisms resulting in increased arginase activity and L-arginine deficiency in airway obstruction.
