Research Focus
My research focuses on studying disorders of the diaphragm and other breathing muscles. The respiratory muscles pump air into and out of the lungs, and when these muscles are defective this can lead to respiratory failure and even death. Some disorders of the respiratory muscles are genetic in origin. This is the case for muscular dystrophies and another inherited disease we are studying called Pompe disease. In other patients, weakness of the respiratory muscles is not genetically determined but instead acquired due to another illness. This is especially problematic in critically ill individuals who become dependent upon mechanical ventilation in the intensive care unit, due to a condition called Ventilator-induced diaphragmatic dysfunction. We are investigating the cellular and molecular mechanisms which contribute to these diseases, with a strong emphasis on relating these changes to the overall physiologic function and strength of the muscles. Our primary goal is to develop novel therapies that will help to reverse and/or prevent the development of respiratory muscle weakness and failure in patients.
