I received my undergraduate degree and my Ph.D. in Biochemistry from the National University of Ireland, Galway and my postdoctoral training at UC San Francisco.
My research is focused on detection and characterization of proteolytic enzymes involved in infectious diseases. Our research utilizes a mass spectrometry based platform technology to uncover the global proteolytic activity in complex biological samples such as extracts from pathogenic fungi, bacteria and worms. Using this technology, we have uncovered novel proteolytic activities in Schistosoma mansoni, Pseudogymnoascus destructans and Mycobacterium tuberculosis. In addition, we have designed potent inhibitors of the Plasmodium falciparum proteasome. Our group is highly collaborative and we routinely generate substrate specificity profiles of endo- and exo-peptidases that have been isolated from diverse organisms that includes ticks, crustaceans and worms.
