Dr. Spencer is interested in the underlying mechanisms and functional consequences of heparan sulfate proteoglycan interference in various disease pathways, including age-related macular degeneration, glaucoma, emphysema, Alzheimer’s disease, and diabetes. Her quantitative approach to these problems is based on a combination of biochemical, biophysical, and computational techniques.
In a current project on glaucoma, she is using in vitro testing to examine the feasibility of protecting the optic nerve from elevated pressure by modifying the mechanical properties of the extracellular matrix through injections of replacement materials (proteoglycans, growth factors, etc.). She is also involved in the development of an innovative computational technique for predicting patterns of domain organization within a population of heparan sulfate chains that could lead to new strategies in understanding heparan sulfate-protein interactions and to new drugs for those interactions associated with disease.
