The best candidates for research in my laboratory have an interest in the
evolution of the immune response to pathogens, and training in immunology
and genetics. Previous research experience in molecular biology is a valuable
asset.
Undergraduates are encouraged to pursue summer studentships and Honours research projects in my lab provided they have taken the Introductory Immunology course INTD 371 or equivalent. Summer research projects will depend on obtaining NSERC or AHFMR support, so a GPA of 8 on the 9 scale is required.
Publications
Our research interest is in the evolution of the immune system. Very recently we reviewed the progress in identifying the effectors and receptors involved in innate immunity in lower vertebrates. Previously, I reviewed the revolution molecular approaches were having on the study of the evolution of the immune system.

Characterization
of the immune system of trout.
This work has a practical application
in contributing to our understanding of immune defense against an intracellular
pathogen causing Whirling Disease that is presently decimating wild stocks
of rainbow trout.

Identification
of naturally occurring null HLA alleles.
We discovered that a single stop codon in frame resulted in the complete degradation of the messenger RNA encoding the allele. Since these mutations arise in tumors and in the population, we characterized the effect of point mutations throughout the gene.

Immunogenetic
defects of ducks.
We determined that ducks have genetic defects in their two main antibody genes. The IgY gene (the avian IgG homologue) contains an additional exon that is used in making a truncated antibody lacking the Fc region. This truncated antibody cannot participate in the normal effector functions of the IgG antibody. Our characterization of the duck immunoglobulin locus revealed that the IgA gene is reversed in the locus. While this would potentially make class switching difficult, we did demonstrate that IgA is expressed in the appropriate tissues. These defects make the duck particularly susceptible to infections.
