Research Interests:Metalloproteases and their Inhibitors
My research deals with the biochemistry of zinc metalloproteinases and their inhibitors. I am currently investigating the interaction between the serralysins, a family of bacterial metalloproteinases, and their endogenous inhibitors. I am also interested in the biochemistry of the matrix metalloproteinases.
