Creative and Activities:
Intellectual Property:

1) US Patent 7,592,322: "RNAi modulation of RSV, PIV and other respiratory viruses and uses thereof ".

Our research in RNA interference (RNAi), particularly in antiviral RNAi and nasal delivery, has received international acclaim. Our first paper in this area was the "All-time most accessed paper" (Click here: for many years. Our second paper, which came out in Nature Medicine, forms the basis of the Patent and our Licensing Agreement with Alnylam (Cambridge, MA), currently the largest RNAi Company. Of note, the Scientific Advisory Board of Alnylam includes major leaders in the RNA area (Bartel, Tuschl, Harlow, Sharp, Schimmel, Zamore) (Click here for the joint Alnylam-USA Press Release: In fact, this is now a top-priority project in Alnylam's drug development pipeline and has successfully completed Phase 2 clinical trial. If eventually approved, this will be the first antiviral RNAi in the pharmacy.
This work has been featured on NOVA Science Now (in PBS) as one of the landmark discoveries in Medicine (Click here:

2) US Patent 5,831,069: "Antisense oligonucleotides against nonstructural proteins NS1 and NS2 of respiratory syncytial virus and uses thereof".
Research Interests:
Suppression of innate immunity by RNA viruses; Interactions between host and Toxoplasma gondii; RNA interference in lower eukaryotes.
