Research Interests

I am interested in the evolution of immunity, focusing on the chicken MHC.

Among our discoveries are the

1. existence of single dominantly-expressed chicken class I and class II molecules which determine the immune response to pathogens and vaccines,

2. importance of co-evolution between polymorphic genes that lead to the expression of a single class I molecule, and

3. presence of lectin-like (NK) receptor and CD1 genes suggesting they were present in the primordial MHC.

I continue to explore the

1. roles of chicken MHC molecules in resistance to pathogens and response to vaccines,

2. roles of polymorphism and co-evolution for MHC genes involved in antigen presentation, and

3. ramifications of our findings for the evolutionary history of the MHC.

My long-term plans include whole genome studies in chickens, development of chickens as a system with a smooth transition between field and laboratory for study of natural pathogens in a natural host, and work on other vertebrates.
