Professor Charles Roth received a 5-year NIH award for $1 million to support his project entitled "Efficient and Selective Delivery of Antisense Oligonucleotides". The research project, which involves a collaboration with Professor Joachim Kohn (Chemistry), includes the development of a family of ligand-bearing, polymeric materials for delivery of nucleic acids to cells, and their use in identifying and overcoming rate-limiting steps to delivery.
