Research Interests

  • My laboratory pursues basic and clinical research topics in molecular imaging and nanotechnology. We design novel methods, hardware, and software for clinical and molecular imaging with ultrasound and MRI. Cross disciplinary nanomedicine research is conducted with many collaborators. Current areas of research interest include:
  • 1. Development of molecularly targeted peptide nanostructures for control of gene function by delivery of oligonucleotides and mRNA to modulate inflammatory diseases.
  • 2. The design of theranostic biocompatible perfluorocarbon nanostructures for quantitative magnetic resonance imaging and delivery of pharmaceutical agents in atherosclerosis and heart failure.
  • 3. The design and synthesis of protease-activatible nanostructures for therapeutic use in metastatic cancer and atherosclerosis.
  • 4. The development of nanostructures that restore cellular autophagy in diseases such as muscular dystrophy and heart failure.
