I became interested in biology and genetics while pursuing my undergraduate degree in Molecular Biology and Biotechnology at McMaster University in Hamilton , Ontario , Canada . During my Ph.D. training at the University of Toronto, under the supervision of Dr. Tony Pawson (http://pawsonlab.mshri.on.ca), my research focused on understanding the role of modular protein domains in the regulation of protein kinase based signal transduction pathways. My interests in protein kinase signaling and the role of modular domains as building blocks to assemble multiprotein regulatory complexes brought me to the Dr. Gabriel Nunez's laboratory for my postdoctoral studies. Here I am interested in understanding the molecular mechanisms by which the intracellular Nod-like family of innate immune receptors (NLRs) regulate inflammation, cell death, and host defense. The modular domain architecture of this family is highly conserved across vertebrates and is commonly used to further subclassify NLR family members. One subclass of NLRs initiates a cascade of downstream kinases culminating in the regulation of critical transcriptional regulators such as the NF-kB family while another subclass plays an important role in the regulation of the inflammatory protease, Caspase-1. Clinically the deregulation of several members of the Nod-like family of receptors has been implicated in a variety of human inflammatory disorders.
