I am interested in the effects of parasites on physiological trade-offs. Do parasites select for increased investment in immune function? Do hormones coordinate life history characteristics and immune investment? Does exposure to different parasites in different habitats contribute to differentiation of populations?
My graduate work on dark-eyed juncos asks if parasites or immune function can explain some of the population differences that have been found in hormone levels. I did preliminary field work in VA at the Mountain Lake Biological Station, and in 2012 I worked in CA comparing the UCSD and Laguna Mountain populations.
