Associate Professor

Specialty Areas:

Regulation of mucin secretion in lung diseases. Delivery of therapeutic oligonucleotides to the lung. Targeting of therapeutic molecules to the airway epithelium.

Research Focus:

Dr. Kreda’s research focuses on identifying signaling molecules/pathways that regulate airway mucin secretion. The main goal is to uncover potential targets of clinical interest to control abnormal luminal mucus accumulation in lung diseases. Her lab has developed and optimized in vitro and in vivo models of lung diseases with excessive mucus production and quantitative assays for therapeutic drug testing and evaluation of mucin production in airway epithelia.

Dr. Kreda’s lab also studies mechanisms of delivery of therapeutic molecules in the lung. The main goal is to develop novel and efficacious delivery strategies of therapeutic nucleic acids in obstructive lung diseases. The Kreda lab is currently involved in designing an efficacious oligonucleotide-based therapeutic approach to correct cystic fibrosis mutations in patients resilient to modulator therapies (Press release June 2021). The lab uses state-of-the art technologies and patient-oriented models for precision medicine approaches.

Funding sources for Dr. Kreda’s lab include Cystic Fibrosis Foundation, National Institutes of Health (NIH), NCTraCS (the NIH CTSA at UNC-CH), Initos Pharmaceuticals, AstraZeneca, and Forest Research Institute (now AstraZeneca). Her lab has successful collaborations with scientists from academic and pharmaceutical institutions to develop and test novel drugs for their potential therapeutic use in obstructive lung diseases.
