Anna Ermund is a senior researcher at the University of Gothenburg, a position she has held since 2015. She received her PhD in experimental clinical pharmacology in 2008 and has done a postdoc at Cornell University before joining Professor Gunnar C. Hansson and the Mucin Biology Group in 2010. Dr. Ermund has published several papers on mucus properties in the intestine, the most recent about the beneficial effect of a calcium chelator drug on the attached mucus in cystic fibrosis. Recently she has started to work on characterizing the mucociliary clearance system in the airways in health and disease and brought forth some new concepts for how the airway mucus system works. This is what will be presented and discussed at the NACFC.
