Research interests

  • Respiratory physiology and the treatment of respiratory diseases;
  • Application of computational fluid dynamics (CFD) to quantify respiratory airflow and its role in the pathophysiology of respiratory diseases, such as nasal obstruction, obstructive sleep apnea, chronic sinusitis, and subglottic stenosis;
  • Virtual surgery planning to improve surgical outcomes for patients with nasal airway obstruction;
  • Optimizing the properties of inhaled medications (sprays, nebulizers, inhalers) to maximize the dose delivered to specific sites in the respiratory tract (e.g., paranasal sinuses, vocal folds);
  • Systems biology;
  • Mathematical models of ion transport in respiratory epithelia to understand airway surface liquid (ASL) regulation, and particularly ASL dehydration in cystic fibrosis (CF) patients.
