The lungs are a delicate, yet, vital organ for which serious disease can be extremely dangerous. According the WHO, 3 of the top 10 leading causes of death are related to the lungs. Mucus is a natural substance produced by the body for lubrication, digestion, foreign object removal and other tasks. Too much mucus, however, can cause problems with breathing and obstruction of the airways – a feature of highly deadly diseases like COPD.  At the Freeman Lab, our goal is to develop the safest and most effective ways to reverse the effects of mucus airway obstruction.
