Research Interests

My research aims to understand the molecular mechanisms of pulmonary inflammation and how it resolves. Specifically, I investigate transcriptional gene regulation, macrophage-lung structural cell interactions, and the role of extracellular vesicle cargo in ARDS pathophysiology.

  • Peptide inhibitors to target Calcineurin-NFATc3 signaling.
  • Extracellular vesicles in ALI/ARDS.
  • PU.1- DNA binding interactions.
  • Metabolites of arachidonic acid in inflammation.
