If you look at parasite infections in nature, there's a huge amount of variation in who gets sick, and how sick he/she/they get. What ecological and evolutionary factors underlie this variation in the outcome of parasite infection? How does parasite fitness relate to how sick it makes its host? These are questions I address using experiments in host-parasite systems such as the Asian Tiger mosquito and it's protozoan parasite Ascogregarina taiwanensis, the Cabbage Looper moth and it's viral parasite AcMNPV, and the tent caterpillar and it's NPV. These days, for better or for worse, I spend most of my time chasing after our preschooler, potty-training our infant, and chasing after referees to review manuscripts for the new journal I help run, called Evolutionary Applications. Thank goodness I don't need to potty-train reviewers too. Check it out at www.evolutionaryapplications.org. Judy, I'll publish a paper again some day, I promise!
