Host-parasite interactions

Parasites have shaped the evolution of vertebrate host immune systems. The major histocompatibility complex (MHC) represents one of the best-studied gene regions of the vertebrate immune system and is crucial for effective adaptive immune response. Understanding how diversity is maintained at this gene region furthers our understanding of natural selection and antagonistic coevolution.

Mate choice

Mating preferences and kin recognition for individuals with specific immune gene (MHC) profiles can provide direct and indirect fitness benefits. Such preferences can also maintain diversity at these immune genes. How MHC genotypes are signaled between kin and potential mates is an outstanding question.

Comparative insights

I am interested in understanding the generality of parasite-mediated selection and sexual selection driving immune gene variation in nature. This requires a macroevolutionary perspective.
