Complex biological fluids & interfaces, nanoscale diagnostics & therapeutics, lung diseases

Our research is focused on using nanotechnology and bioengineering as tools to broaden understanding of the lung airway microenvironment in order to develop state-of-the-art diagnostic and therapeutic approaches. These efforts are built on our group’s expertise in designing novel measurement schemes and bioengineered models, capable of shedding new light on previously unstudied aspects of the lung airways. The nature of this work requires an interdisciplinary and collaborative approach where we work closely with basic and clinical scientists in order to successfully work towards our research goals. Specific areas of interest in our laboratory include:

  • Lung airway mucus clearance in health & disease
  • Host-pathogen interactions in respiratory infections (e.g. influenza)
  • Engineering mucin biomaterials for biology & medicine
  • Overcoming biological barriers to drug & gene delivery
