Dr Rodda’s major research work to date has been in developing strategies to control surface interactions between engineered materials and biological molecules. These are of interest in diverse applications, including in studies of implantable cell scaffolds, cell microenvironments to support and direct stem cell development, low-fouling coatings and biosensors. Previous work has examined both the synthesis and application of novel materials, particularly polymers. He has also previously worked in the development of systems for the detection of biomolecules in complex samples, and in characterising cell responses (particularly neural and stem cells) to biomaterials both in vitro and in vivo. His most recent projects are examining new methods for detecting biomolecules, in particular focusing on the analysis of cell-free DNA for genotyping of cancer.
