Work is in progress in the following areas:

• Investigating the mechanism of release from polymeric delivery systems with concomitant microstructural analysis and mathematical modeling
  
  
• Studying applications of these systems including the development of effective long-term delivery systems for insulin, anti-cancer drugs, growth factors, gene therapy agents and vaccines

• Developing controlled release systems that can be magnetically, ultrasonically, or enzymatically triggered to increase release rates

• Synthesizing new biodegradable polymeric delivery systems which will ultimately be absorbed by the body

• Creating new approaches for delivering drugs such as proteins and genes across complex barriers in the body such as the blood-brain barrier, the intestine, the lung and the skin

• Researching new ways to create tissue and organs including creating new polymer systems for tissue engineering

• Stem cell research including controlling growth and differentiation

• Creating new biomaterials with shape memory or surface switching properties

• Angiogenesis inhibition
