Welcome to the Biomedical Polymer Science Laboratory. We are interested in understanding the interactions of materials and the cells. Our current proejcts focus on using polymers to control the local release of therapeutic molecules and the influence of polymers on cellular phenotype, particularly macrophage polarization.

This website is constantly under construction and will be changing constantly (or at least I'd like it to...). Please return often for updates and news. Please contact Dr. Gemeinhart ( to report any broken or misdirected links.
