Research Interests

  • Lung Epithelial Cell Biology
  • Innate host defense in context of pulmonary infection and inflammation
  • Ubiquitin proteasome pathway

Current Research

My current research projects are being performed with guidance and support from Dr. Rama Mallampalli’s lab, where I am acquiring additional expertise in cell and molecular biology techniques. I am interested in how lung epithelial cells respond to respiratory viral infections and innate immune response in the lungs.
