My group's research spans the areas of homogeneous catalysis, polymer science, inorganic and organic chemistry, and the design of biodegradable macromolecules for biomedical materials. Our group's recent efforts are focused on developing new molecular strategies for generating artificial materials that can mimic the extraordinary structural, functional and biological properties of natural macromolecules. Collaborative efforts with the Wender and Levy groups have led to a new class of degradable RNA delivery agents. Charge-Altering Releasable Transporters, are a class of amphiphilic oligomers derived from degradable cations that are effective for the complexation, delivery and release of RNA, both in cell culture and live animals.
