Our group’s research involves investigation of structure-function correlation of redox active metal and cofactor bound peptides which have been related to several diseases like Alzheimer’s disease and type 2 diabetes. We use various spectroscopic tools to investigate the geometric and electronic structures of these active sites to gain insight into their reactivities. Of particular interest are the interactions of these aberrant species with other biological molecules and pathways that are physiologically relevant to a particular pathology.
